Identifying Your Computer

In most instances, the best way to identify your computer is by the model/type number. The model/type number indicates the various features of the computer, such as the type of microprocessor or whether the computer is a desktop or minitower. You can find this number on the small label on the front of your computer. An example of a model/type number is 6282-54A.

Throughout this book, however, your computer is identified by the number of drive bays offered with these models. If your computer has three drive bays, it is referred to as the 3-bay design. If your computer has four drive bays, it is referred as the 4-bay design. These naming conventions are used only where it is appropriate. Instructions without these naming conventions apply to all computer models.

3-Bay Design

With the cover on, bay 2 in the 3-bay design is not visible. This bay is intended for a hard disk drive, which does not have accessible media such as a CD-ROM drive or diskette drive. The 3-bay design has two expansion slots for adapters, as shown in the rear view below.

The integrated Ethernet is a Plug and Play device that has built-in support for Wake on LAN and a viewable MAC (media access control) address for your computer. (See “System Management Settings” on page 64 for more information.) Device drivers for the Ethernet subsystem are provided on the Ready-to-Configure CD that comes with your computer. If your computer has IBM-preinstalled software, the device drivers are already installed on the hard disk drive. For instructions on connecting a network cable to your computer, refer to Setting Up Your Personal Computer.

System Management Features

Your computer has features that make it possible for a network administrator to manage and control it remotely over a network. These features are:

 Enablement for LANClient Control Manager software  Capable of using remote program load (RPL) and dynamic host configuration

protocol (DHCP)

 Enablement for Wake on LAN  Primary startup sequence and automatic power on startup sequence  Enablement for POST/BIOS updates over a network  Desktop Management Interface (DMI) BIOS and DMI software

For information on these features, refer to “Using System Management Features” on page 32 and “System Management Settings” on page 64.

Audio Support

In some models, an audio adapter is preinstalled. The audio adapter is Sound Blaster compatible and provides a musical instrument digital interface (MIDI) for connecting optional game controls or electronic musical devices. Also, three ports are provided for connecting powered speakers, an audio input device such as a portable CD-ROM, and a microphone.

ISA Bus

Your computer has an industry standard architecture (ISA) bus, which is one of the most widely used and successful input/output (I/O) buses available. The ISA bus is popular because so many adapters and devices have been designed and marketed for it.

Chapter 1. Your IBM Personal Computer 3

PCI Bus

Your computer also has a peripheral component interconnect (PCI) bus. PCI is an advanced bus standard designed to keep up with performance improvements of microprocessor buses and advanced peripheral devices. The PCI bus adds to the capability of the ISA bus, speeding up the exchange of information among the microprocessor and peripheral devices within your computer system.

Expansion with Adapters

By installing adapters, you can expand the capabilities of your computer and take advantage of a variety of peripheral devices and applications. Your computer uses a riser card for connecting adapters to the ISA bus or PCI bus.

High-Capacity Hard Disk Drives

Your computer comes with a hard disk drive that has an enhanced integrated drive electronics (EIDE) interface. The hard disk drive is a SMART (self-monitoring, analysis and reporting technology) drive capable of predicting potential problems. When used with the proper software applications, the SMART hard disk drive protects data and improves reliability.

CD-ROM Drive

In some models, a CD-ROM drive is preinstalled. A CD-ROM (compact disc read-only memory) drive plays back or reads information from a CD providing quick access to large amounts of information. A compact disc can store more than 650 MB of data, such as the large files needed for audio, full-motion video, and animated graphics.

Parallel Port

Your computer has one parallel port. The parallel port is most often used to communicate with a parallel printer, but it can also be used with other parallel devices.

The parallel port can operate in several different modes. The default mode for your computer is standard parallel port (SPP). However, your computer also supports the extended capabilities port/enhanced parallel port (ECP/EPP) modes. For more information, see “Changing Parallel Port Settings” on page 51.

4 Using Your Personal Computer

Serial Ports

Your computer has two standard, 16550-UART serial ports that can be used to connect devices such as modems and printers.

The Universal Serial Bus (USB) interface is based on a new technology that adds more diversity and capabilities to personal computers. Two USB connectors are provided so you can take advantage of new USB devices as they become available.

The USB interface incorporates Plug and Play technology which allows you to install devices that configure automatically. Also, you can install and remove devices without having to shut off your computer. In addition, an option called a hub enables you to plug in more than one device at a time. A hub converts a single USB connector into multiple ports where USB devices can be attached.

Note: Your computer does not support a keyboard or mouse attached to the USB

port.

Ease-of-Use Features

Using the computer is easier with features such as Plug and Play technology, diagnostic programs, and system management features.

Support for Plug and Play technology is built into the system board of your computer. This allows you to add Plug and Play adapters that are self-configuring, provided that the requested resources are not already in use. In most cases, Plug and Play technology eliminates having to manually configure a device by setting switches or jumpers or by setting ISA legacy resources.

If you have a problem with your computer, a diagnostic program called QAPlus/PRO helps determine if a hardware component is causing the problem. QAPlus/PRO and other operating system-specific diagnostic programs are included on the Ready-to-Configure CD that comes with your computer.

Note: Create the QAPlus/PRO diskette as soon as possible, so that you will be

ready to diagnose a problem if one should occur.

If your computer is properly connected to a network, you can take advantage of advanced system management features, such as Wake on LAN, RPL, and DHCP. For more information, see “Using System Management Features” on page 32.

Chapter 2. Arranging Your Workspace

To get the most from your computer, arrange both the equipment you use and your work area to suit your needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation, and the location of electrical outlets also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few guidelines to help you find a position that suits you best.

Sitting in the same position for a long time causes fatigue. A good chair can make a big difference. The backrest and seat should adjust independently and provide good support. The seat should have a curved front to relieve pressure on the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor and your wrists in a neutral, comfortable position. Try to keep a light touch on the keyboard and your hands and fingers relaxed. You can change the angle of the keyboard for maximum comfort by adjusting the position of the keyboard feet.

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to 24 in.), and position it so you can view it without having to twist your body.

Lower Back Support

Seat Height

Viewing Distance

Glare and Lighting

Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources. Place the monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or blinds to block the sunlight. You might have to adjust the Brightness and Contrast controls on the monitor as the room lighting changes throughout the day.

Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare.

Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth moistened with a nonabrasive liquid glass cleaner.

Air Circulation

Your computer and monitor produce heat. The computer has a fan that pulls in fresh air and forces out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the computer and monitor so that nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is not blowing on someone else.

Electrical Outlets and Cable Lengths

The location of electrical outlets and the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your computer.

When arranging your workspace:

 Avoid the use of extension cords. When possible, plug the computer power

cord directly into an electrical outlet.

 Keep power cords and cables neatly routed away from walkways and other

areas where they might get kicked accidentally.

For more information about power cords, see “Power Cord Notice” on page 131.

20 Using Your Personal Computer

Starting Your Computer

Note: If your computer is configured correctly, it can be started remotely over a

network. For more information, see “Wake on LAN” on page 69.

1. Turn on all devices connected to the computer.

2. Press and release the power switch on your computer. This starts the computer, and the following actions occur:

a. The IBM logo appears centered on the screen. b. The power-on self-test (POST) is performed. You can recognize this by

looking for the increasing number in the upper-left corner of the screen. This number is the amount of memory being tested by POST. When the number stops, the memory is tested and POST is complete.

If POST detects a problem, you hear multiple beeps (or no beep) and an error message appears on the screen. Write down any error code numbers and descriptions, and see “Solving POST Problems” on page 74 and “POST Error Message Charts” on page 77 for more information. (If you do not hear a beep during POST, refer to “Troubleshooting Charts” on page 96. You might need to have your computer serviced.)

c. The computer allows you to enter the Configuration/Setup Utility program

(by pressing F1) or run a fast POST (by pressing Esc). These options are shown in the lower-left corner of the screen.

3. If the computer is not password protected, you hear a beep, and the first screen of the operating system or application program appears.

If the computer is password protected, a prompt is displayed for entering either the power-on or administrator password. If both a power-on and an administrator password have been set, you must type either password at the password prompt. (Refer to “Using Passwords” on page 53 for instructions on setting and using passwords.) Type your password at the prompt and press Enter. The first screen of the operating system or application program appears.

Models with integrated Ethernet have special factory settings that affect the primary startup sequence. If your model comes with integrated Ethernet, the computer tries to perform a remote program load (RPL) of the operating system. If RPL is unsuccessful, several messages might appear and then your computer loads the operating system from the hard disk drive. For more information on these factory settings, see “Network-Enabled Startup Sequence” on page 66. For information on the messages that might appear, see “Error Messages Specific to the Integrated Ethernet” on page 107.

Chapter 3. Operating Your Computer

Shutting Down Your Computer

When you are ready to turn off your computer, follow the shutdown procedures for your operating system to prevent the loss of unsaved data or damage to your software programs. See your operating system documentation for instructions.

In some operating systems, you can set up the computer to automatically turn off after the operating system has shut down. If you have not selected this setting, you must manually turn off the computer by pressing and releasing the power switch.

Important

If you plan to restart your computer, do not use Ctrl+Alt+Del while the operating system is running. Instead, follow the shutdown procedure for your operating system, turn off the computer by pressing and releasing the power switch, wait a few seconds until all the status-indicator lights are off, and then follow the procedures in “Starting Your Computer” on page 21.

22 Using Your Personal Computer

Using a Mouse

A mouse is a device that you use to point to and select objects on the monitor screen. The mouse that comes with your computer attaches with a cable to the mouse port on the back of the computer. For information on connecting the mouse, see Setting Up Your Personal Computer.

Note: Optional mouse devices might connect to the computer through a serial port.

A mouse device cannot be connected through the USB port.

With a mouse, you can move the pointer on the screen. If you have never used a mouse before, it might feel a bit awkward at first. However, with a little practice, the mouse movements will seem natural.

To set up the mouse, place the mouse beside the keyboard on a flat surface or mouse pad. A mouse pad is a flat, smooth foam-rubber pad available at most computer stores. The mouse has a ball on the bottom, so working on a flat, smooth surface is important. Most operating systems allow you to configure the mouse buttons for either right-hand or left-hand operation. When a two-button mouse is configured for right-handed user, the left button is used for most tasks. When a two-button mouse is configured for a left-handed user, the right button is used for most tasks. For more information, see your operating system documentation.

To use the mouse, slide it from side to side and forward and backward over a flat surface. When you see an item that you want to select on the screen, simply move the pointer to that item (this is called pointing), and press and release either the left or right button on the mouse (this is called clicking).

To learn how to use the mouse with the software in your computer, see the documentation accompanying the software. Some programs support only one mouse button, others support two, and some support three. Despite the differences, some terms are fairly standard throughout the industry.

Point Move the mouse so the pointer is on the object you want. Click Press and release the mouse button once. Double-click Rapidly press and release the mouse button twice. Drag Point to an object, press the mouse button, and hold it down as you

move the mouse to relocate the object.

Drop After dragging an object to a new location, release the mouse button.

Chapter 3. Operating Your Computer 23

Using a Diskette Drive

You can use 3.5-inch diskettes in the diskette drive of your computer. If you want to use 5.25-inch diskettes, you must install a 5.25-inch diskette drive. (Refer to Installing Options in Your Personal Computer for instructions on installing optional diskette drives.)

The information that follows will help you identify and use 3.5-inch diskettes.

Identifying Diskettes

The labeling on 3.5-inch diskettes is not consistent among manufacturers. Some diskettes are labeled with the letters DD or HD to identify the diskette type; other diskettes might not be labeled. However, the appearance of the lower-right corner of a 3.5-inch diskette always can be used to identify the diskette type, as shown in the following illustrations.

Handling and Storing Diskettes

Inside the protective diskette case is a flexible disk with a magnetic-sensitive coating. This disk can be damaged by heat, dust, a magnetic field, or even a fingerprint. Use the following guidelines when handling and storing diskettes.

 Data is stored on the magnetic surface of the diskette. On 3.5-inch diskettes,

this surface is protected by a plastic cover. If the cover is damaged, do not use the diskette. A damaged diskette might damage the diskette drive.

 A protective slide on the top of a 3.5-inch diskette covers part of the magnetic

surface. The diskette drive moves this slide to read data from or write data to the diskette. Do not move this slide, because fingerprints and dust can cause loss of data.

Top

Protective Slide

3.5 Diskette

2.0 MB capacity

 Never touch the magnetic disk itself.  Keep diskettes away from magnets or devices that create a strong magnetic

field, such as electric motors and generators. Diskettes are sensitive to magnets found in television sets, telephones, stereo speakers, and other such items. A magnetic field can erase the data on your diskettes. Do not set diskettes on the monitor or use magnets to attach notes to your computer.

 Do not store diskettes at high temperatures, low temperatures, or in direct

sunlight. Temperatures ranging from 4° to 53°C (39° to 127°F) are acceptable for

3.5-inch diskettes. Keep diskettes away from heat. The plastic outer covering might warp, damaging the diskette.

Chapter 3. Operating Your Computer 25

Labeling Diskettes

Before using a diskette, label it so that you can identify the data stored on it. Labels usually come in the package with the diskettes. Diskette labels can become a problem if you do not apply them correctly. Loose edges or an excessive buildup of labels can prevent the diskette from being inserted or ejected.

To prevent this problem, take the following precautions:

 Remove an old label before you apply a new one.  Apply labels carefully to ensure that all edges are secure.  Apply labels only to the front of diskettes. Do not place a label where it

interferes with the protective slide or covers an opening in the protective diskette case.

Inserting and Removing Diskettes

Important

Always make certain that the diskette drive is empty before inserting a diskette. If the diskette eject button is flush with the front of the computer, a diskette can be inserted. If the diskette eject button is not flush with the computer, a diskette is already inserted.

To insert a 3.5-inch diskette, hold the diskette with the label facing up and insert the end with the protective slide first. Push the diskette into the diskette drive until the diskette clicks into place. The diskette eject button pops out.

To remove the diskette, press the eject button and slide the diskette out of the drive. Do not remove the diskette while the in-use light is on.

Write Protecting Diskettes

It is possible to accidentally format a diskette or unintentionally write data to it. Important information can be written over or lost. For this reason, it is a good idea to write protect important diskettes. You can read data from a write-protected diskette, but you cannot erase or change the data.

Most 3.5-inch diskettes have a write-protect switch that can be used to prevent data from being written to or erased from the diskette. If a 3.5-inch diskette does not have a write-protect switch, it is permanently write protected.

The write-protect switch is located on the back of 3.5-inch diskettes.

 To allow writing to the diskette, slide the switch so the write-protect window is

covered.

 To prevent writing to the diskette, slide the switch so the write-protect window

Formatting Diskettes

You can buy diskettes either formatted or unformatted. Formatted diskettes are ready to use; unformatted diskettes must be formatted by your operating system before you can use them. The format operation checks a diskette for defects and prepares it for storing data. If data is already stored on the diskette, the format operation writes over it, and the data is lost.

Chapter 3. Operating Your Computer 27

The operating system FORMAT command specifies how to format a specific type of diskette.

Important

Always format diskettes to their correct capacity. Failing to do so might cause unreliable results. Differences such as magnetic coatings, the thickness of the diskette material, and the recording technique used all affect the formatting operation. Refer to your operating-system documentation for detailed information on formatting diskettes.

The following table shows diskette types, their formatted capacities, and the drive type that can be used with each diskette.

3.5-Inch Diskette Type Formatted Capacity

1 MB (MF2DD) 720 KB 1.44 MB 2 MB (MF2HD) 1.44 MB 1.44 MB

Drive Type

Notes:

1. MF2DD = Mini-floppy, two-sided, double density

2. MF2HD = Mini-floppy, two-sided, high density

3. If you are using DOS, use FORMAT A: /F:720 to format a 1 MB diskette in a

1.44 MB drive.

Copying Diskettes

If you are using DOS, you can copy one or more files to or from a diskette using the COPY command. Groups of files can be copied faster using the XCOPY command. Both COPY and XCOPY can copy files to different types of diskettes. For duplicating a diskette, use the DISKCOPY command. DISKCOPY requires that both the source diskette (the diskette you copy from) and the target diskette (the diskette you copy to) be the same type.

Refer to your operating-system documentation for more information on copying diskettes.

28 Using Your Personal Computer

Using a CD-ROM Drive

Some models have a preinstalled CD-ROM drive. CD-ROM (compact disc read-only memory) technology offers quick access to enormous amounts of information. A compact disc can store more than 650 MB of data, such as the large files needed for audio, still and full-motion video, and still and animated graphics. A CD-ROM drive can play back or read from a CD, but it cannot write information to it. CD-ROM drives use industry-standard, 12 cm (4.75-inch) CDs.

Follow these guidelines when using a CD-ROM drive:

 Do not place the drive where there is:

– High temperature – High humidity – Excessive dust

– Excessive vibration or sudden shock – An inclined surface

– Direct sunlight

 Do not insert any object other than a CD into the drive.  Before moving the computer, remove the CD from the drive.

The following illustration shows the controls and status indicator for a preinstalled CD-ROM drive.

Wiping the CD in a circular direction might cause loss of data.

 Do not write or stick paper on the CD.  Do not scratch or mark the CD.  Do not place or store the CD in direct sunlight.  Do not use benzene, thinners, or other cleaners to clean the CD.  Do not drop or bend the CD.

Loading a CD

To load a CD into the CD-ROM drive:

1. Press the Eject/Load button. The tray slides out of the drive. (Do not manually force the tray open.)

2. Place the CD in the tray with the label facing up. If you have placed your computer in a vertical position using the optional floor stand, extend the two CD-retainer clips on the lower side of the CD-ROM drive tray to keep the CD in position as you open and close the drive.

3. Close the tray by pressing the Eject/Load button, or by gently pushing the tray forward. When the tray is closed, the indicator light on the front of the drive will activate to indicate that the drive is in use.

4. To eject the CD, press the Eject/Load button. When the tray slides out, carefully remove the CD.

5. Close the tray by pressing the Eject/Load button, or by gently pushing the tray forward.

Note: If the tray does not slide out of the drive when you press the Eject/Load

button, insert the pointed end of a large paper clip into the emergency eject hole located above and to the left of the CD-ROM indicator light.

If you have installed a CD-ROM drive yourself and need additional information about the drive, refer to the documentation that comes with the CD-ROM drive.

30 Using Your Personal Computer

Using Audio Features

If your computer comes with a preinstalled audio adapter, it is Sound Blaster compatible and capable of playing and recording sounds.

The device drivers for the preinstalled audio adapter are preinstalled on the hard disk drive. If you install this adapter as an option, use the device drivers on the Ready-to-Configure CD.

If you connect an optional device to the audio adapter, follow the manufacturer's instructions (device drivers might also be required). Contact the manufacturer for information on the necessary device drivers.

The following ports are available on the audio adapter:

 Game/MIDI (musical instrument digital interface) port for connecting a game

control or a musical device such as an electronic keyboard.

 Line in port for connecting musical devices such as a portable CD-ROM or

stereo.

 Line out port for connecting powered speakers. Your audio system requires a

set of speakers connected to the line output in order to hear audio from the adapter. These speakers must be powered (with a built-in amplifier). In general, any powered speakers designed for use with personal computers might be used with your audio adapter. These speakers are available with a wide range of features and power output.

 Microphone in for connecting a microphone.

GAME/MIDI OUT LINE IN MIC

An electronic device connected to the Game/MIDI port might require an optional adapter cable. For more information, refer to the documentation that comes with the electronic device.

Chapter 3. Operating Your Computer

Using System Management Features

This section is intended primarily for network administrators. It describes features of your computer that make it possible for a network administrator to remotely manage and control your computer.

The BIOS (basic input output system) of your computer supports an interface called Desktop Management Interface (DMI). DMI is a mechanism for gathering information about the hardware and software in your computer to enable network administrators to remotely monitor and control computers in a network environment. DMI can be used to remotely track many types of information about computers, including serial numbers, memory attributes, product-specific characteristics of installed peripherals, and operating system configuration information. This information can be accessed using a DMI browser. DMI browsers are provided by all major operating systems and all major LAN management packages, including TME 10 NetFinity, Intel LANDesk, and Microsoft SMS.

The Wake on LAN feature can be used by a network administrator to turn on your computer from a remote location. When Wake on LAN is used in conjunction with network management software, such as LANClient Control Manager and TME 10 NetFinity (provided on the Ready-to-Configure CD that comes with your computer), many types of functions, such as data transfers, software updates, and POST/BIOS flashes can be performed remotely on your computer and other Wake on LAN-enabled computers linked to your network. These functions can be done after hours and on weekends, which saves time and increases productivity since users are not interrupted during normal working hours. Refer to “Wake on LAN” on page 69 for further information.

Other features such as remote program load (RPL) and dynamic host configuration protocol (DHCP) also allow a network administrator to remotely control your computer. If you use remote program load in conjunction with LANClient Control Manager software, you can use a feature called Hybrid RPL. Using LANClient Control Manager, you set up your computer by installing hybrid images (or files) on the hard disk drive. Then, each time the computer starts from the network, LANClient Control Manager recognizes your computer as a Hybrid RPL client and a bootstrap program is downloaded to your computer. This bootstrap program is small and helps prevent network congestion. Working off the hybrid images, the bootstrap program initiates the startup process from the hard disk drive of your computer. An advantage to Hybrid RPL is that the network load associated with standard RPL is avoided. For more information on these two features, refer to “RPL and DHCP” on page 65.

32 Using Your Personal Computer

Updating the POST/BIOS

POST/BIOS is the basic layer of software built into every IBM computer. POST (power-on self-test) is a set of tests and procedures that is performed every time you turn on your computer. The BIOS (basic input output system) is a layer of software that translates instructions from other layers of software into electrical signals that the computer hardware can understand. Also included in the POST/BIOS is the Configuration/Setup Utility program, which enables you to view and change the configuration and setup of your computer.

In the past, the POST/BIOS was contained in a read-only memory (ROM) module on the system board. If you wanted to update POST routines, BIOS instructions, and the Configuration/Setup Utility program, you had to disassemble the computer and replace modules, or you had to replace the system board. Now, a module called electrically erasable programmable read-only memory (EEPROM, also referred to as flash memory) has replaced the ROM module on the system board. You can easily update POST information, the BIOS code, and the Configuration/Setup Utility program in your computer from an update diskette. This procedure is often referred to as flashing the POST/BIOS.

If your computer is properly connected to a network, you can update the POST/BIOS over the network. For further information, refer to “Update POST/BIOS from Network” on page 69.

As part of the continuing work to improve quality, IBM might make changes and enhancements to the POST/BIOS. When updates are released, they are available via download files on the World Wide Web (http://www.pc.ibm.com) or through the PC Company Bulletin Board Service (see “Using Electronic Support Services” on page 109). Instructions for using POST/BIOS updates will be available in a README file included in the download files.

Chapter 4. Taking Care of Your Computer

This chapter provides guidelines for the proper handling and care of your computer.

Basics

Here are some basic points about keeping your computer functioning properly:

 Keep your computer in a clean, dry environment. Make sure it rests on a flat,

sturdy surface.

 Do not place items on top of the monitor or cover any of the vents in the

monitor or computer. These vents provide air flow to keep your computer from overheating.

 Keep food and drinks away from all parts of your computer. Food particles

and spills will make the keyboard and mouse sticky and unusable.

 Do not get the power switches or other controls wet. Moisture can damage

these parts and cause an electrical hazard.

 Always disconnect a power cord by grasping the plug, not the cord.

Cleaning Your Computer

It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free operation.

CAUTION: Be sure to turn off the computer and monitor power switches before cleaning the computer and monitor screen.

Computer and Keyboard

Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer.

36 Using Your Personal Computer

Replacing the Battery

Your computer has a special type of memory that maintains the date, time, and the settings for built-in features, such as serial- and parallel-port assignments (configuration). A battery keeps this information active when you turn off the computer.

The battery requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An error message is displayed when you turn on the computer.

Refer to “Lithium Battery Notice” on page vii of this publication and Installing Options in Your Personal Computer for information about replacing the battery.

If you replace the original lithium battery with a heavy-metal battery or a battery with heavy-metal components, be aware of the following environmental consideration: batteries and accumulators that contain heavy metals must not be disposed of with normal domestic waste. They will be taken back free of charge by the manufacturer, distributor, or representative to be recycled or disposed of in a proper manner. For further information on battery disposal, call IBM at 1-800-IBM-4333 (1-800-426-4333) in the U.S. For information outside of the U.S., contact your IBM reseller or marketing representative.

Chapter 4. Taking Care of Your Computer 37

Moving Your Computer

CAUTION:

 Do not move your computer while it is on. Always turn off the computer

before you move it.

 Do not risk injury by moving or lifting the computer by yourself. Ask

another person to help you.

Normal shipping and handling can cause loss of data from a hard disk. If your computer has a hard disk drive, take the following precautions:

1. Back up all files and data from the hard disk. Operating systems can vary in the way they perform backup procedures. Some

operating systems save only data files, while others make copies of application program files and data files. Refer to your operating system documentation for information about software backup.

2. Remove all media (diskettes, compact discs, tapes, and so on) from the drives.

3. Turn off the computer and all attached devices. Your hard disk drive automatically parks the read/write heads in a nondata area. This process prevents damage to the hard disk.

4. Unplug the power cords from electrical outlets.

5. Note where you have attached your cables to the rear of the computer; then remove them.

6. If you saved the original shipping cartons and packing materials, use them to pack the units. If you are using different cartons, cushion the units to avoid any damage.

46 Using Your Personal Computer

Changing Monitor Settings

Your computer has a graphics controller. SVGA is a video standard for displaying text and graphic images on a monitor screen. Like other video standards, SVGA supports a variety of video modes. Video modes are different combinations of resolution, refresh rate, and color defined by a video standard for displaying text or graphics.

SVGA provides higher-resolution graphics, faster refresh rates, and more colors than previous video standards, such as video graphics array (VGA). At the same time, SVGA supports all standard VGA modes.

To get the best possible image on your screen and to reduce or eliminate flicker, you might need to reset the resolution and refresh rate of your monitor. Refer to your operating system documentation for further information on monitor settings.

Important

Before you change any monitor settings, be sure to review the information that comes with your monitor. Using a resolution or refresh rate that is not supported by your monitor might cause the screen to become unreadable and damage the monitor. The information that comes with your monitor usually includes the resolutions and refresh rates that the monitor supports. If you need additional information, contact the manufacturer of the monitor.

To minimize screen flicker and jitter, set your monitor for the highest noninterlaced refresh rate that the monitor supports. If your monitor complies with the VESA Display Data Channel (DDC) standard, it is probably already set to the highest refresh rate that the monitor and graphics controller can support. If you are not sure if your monitor is DDC-compliant, refer to the documentation provided with the monitor.

To change the monitor settings, select Devices and I/O Ports and then Video Setup from the Configuration/Setup Utility program menu.

2. If 2 MB of memory is required for the video mode, an optional 1 MB of memory must be installed in the system board.

Some application programs require video device drivers to use SVGA modes. If your computer has IBM-preinstalled software, the video device drivers are included and instructions are provided online. If your software is not preinstalled, the video device drivers are on the Ready-to-Configure CD.

Some application programs provide their own video device drivers to take advantage of SVGA modes. These device drivers are installed through a setup program built into the application program. Setting up these applications to operate in SVGA modes might be confusing because terminology for these modes is not consistent throughout the industry. If you are uncertain about the terminology used by your application program, refer to the documentation that comes with the application for additional information.

Changing Serial Port Settings

If you add a serial adapter or use special hardware or software that causes a configuration conflict, you might need to change the serial port settings. The serial port can use any of the following settings:

 The four available port addresses are (in hex): 3F8, 2F8, 3E8, 2E8.  The two recommended IRQ assignments are: IRQ 4 and IRQ 3. You can also use

IRQ 9, IRQ 10, IRQ 11, IRQ 14, and IRQ 15, but these settings might not work with some operating systems and applications.

To change the serial port settings:

1. Start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility Program” on page 39).

2. Select Devices and I/O Ports from the Configuration/Setup Utility program menu.

3. Select Serial Port Setup.

4. Use the arrow keys to select the settings for Serial Port A Address or Serial Port A IRQ.

5. Press Esc to return to the Configuration/Setup Utility program menu.

6. Before you exit from the program, select Save Settings from the Configuration/Setup Utility program menu.

7. To exit from the Configuration/Setup Utility program, press Esc and follow the instructions on the screen.

Note: For more information on the serial ports, see Understanding Your Personal

Computer.

50 Using Your Personal Computer

Changing Parallel Port Settings

If you add a parallel adapter or use special hardware or software that causes a configuration conflict, you might need to change the parallel port settings.

The parallel port can operate in several different modes. The default mode for your computer is SPP (standard parallel port). However, your computer also supports the ECP/EPP (extended capabilities port/enhanced parallel port) mode. ECP/EPP has two advantages over SPP. When your computer is in ECP/EPP mode, you can print documents faster than when the computer is in SPP mode, and you can attach devices other than printers, such as communication and storage devices, to the parallel port. You can set modes of operation for the parallel port using the Configuration/Setup Utility program.

The parallel port can use any of the following settings:

 The three available port addresses are (in hex): 3BC, 378, and 278.  The two available IRQ assignments are: IRQ 7 and IRQ 5.

To change the parallel port settings:

1. Start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility Program” on page 39).

2. Select Devices and I/O Ports from the Configuration/Setup Utility program menu.

3. Select Parallel Port Setup.

4. Use the arrow keys to select the settings.

5. Press Esc to return to the Configuration/Setup Utility program menu.

6. Before you exit from the program, select Save Settings from the Configuration/Setup Utility program menu.

Note: For more information on the parallel port, see Understanding Your Personal

Computer.

Chapter 5. Using the Configuration/Setup Utility Program 51

Changing Plug and Play Control Features

If you are installing a Plug and Play adapter or other device and experience problems, you might need to change certain settings in Plug and Play Control in the Configuration/Setup Utility program.

Note: If you experience any error message related to Plug and Play adapters or

devices, see “POST Error Message Charts” on page 77 for complete information on solving the problem.

A setting that might affect the way a Plug and Play adapter behaves is the Address Decode setting. Most Plug and Play adapters use 16-bit address decoding (this is the default setting for Address Decode.). Some Plug and Play adapters have not fully implemented this addressing scheme. If you are experiencing problems with a Plug and Play adapter, changing the address decoding to 10-bit might fix the problem. Conversely, if you are experiencing an 1852 error message, changing the address decode setting to 16-bit might fix the problem.

Another setting that affects any type of Plug and Play device is the Plug and Play Operating System setting. If you install a Plug and Play adapter or device and experience a 185x error messages, and your computer will be loading a Plug and Play-compliant operating system, set this value to Yes.

Note: Check your operating system documentation to determine if it supports this

function.

The 185x error messages occur because the computer is unable to configure all adapters and devices in the system due to conflicting resource assignments. Selecting Yes allows the configuration of Plug and Play devices to be performed by the operating system.

To change Plug and Play control settings, select Advanced Setup and then Plug and

Play Control. The next menu displays Address Decode and Plug and Play Operating System.

52 Using Your Personal Computer

Using Passwords

Two types of password protection are available to help you secure your computer and the information you store in it. The power-on password feature deters unauthorized persons from gaining access to the information stored in your computer. The administrator password feature helps prevent unauthorized persons from accessing the Configuration/Setup Utility program and changing the setup of your computer. If you are responsible for maintaining the settings of several computers, you might want to set an administrator password.

Other password security features might be available through your operating system or network.

Power-On Password

You do not need a power-on password to use your computer, but setting this type of password deters unauthorized persons from using your computer. When a power-on password is set, you must type the password at the password prompt that appears as the computer starts.

When you set the power-on password, you can choose one of three password prompt modes:

On In On mode, you are prompted for the power-on password when you

turn on the computer. Until the correct password is entered, the computer will not run the CONFIG.SYS or AUTOEXEC.BAT instructions, the operating system will not start, and the keyboard will remain locked. If you have a mouse connected to the mouse port, it also will remain locked. If you have a mouse connected to a serial port, it will be activated when the computer is started, regardless of whether a password is set.

Off In Off mode (also referred to as Unattended Start mode), you are not

prompted to enter your power-on password when you turn on the computer. The computer will run the CONFIG.SYS and AUTOEXEC.BAT instructions and start the operating system. However, if you have a mouse connected to the mouse port, refer to the following text box.

CONFIG.SYS and AUTOEXEC.BAT do not exist with some operating systems, such as Windows NT.

Chapter 5. Using the Configuration/Setup Utility Program

Important Information for Mouse Users

This information applies only to those who have a mouse connected to the mouse port; a serial mouse is not affected by the Off mode.

The Off mode prevents the computer from detecting that a mouse is attached. Because the mouse device driver will not be loaded automatically through the CONFIG.SYS or AUTOEXEC.BAT files in this mode, an error message that the mouse port is disabled will appear and the computer will halt. To enable the operating system to load without displaying the error message, read the information below that applies to your operating system.

If you are using OS/2, do one of the following before enabling the Off mode:

 Set the CONFIG.SYS file so the operating system does not stop on

a device-driver error. To do this, put the command "PAUSEONERROR=NO" near the top of the CONFIG.SYS file.

 Remove the mouse driver statement from the CONFIG.SYS file.

If you are using Windows 95, do the following:

 When the computer is started and the mouse port disabled error

message appears, enter either your power-on or administrator password to enable the keyboard. Then use the keyboard to put a checkmark in the "Do not display this message in the future" checkbox.

Once the operating system starts in the Off mode, the keyboard will remain locked. If you have a mouse connected to the mouse port, it also will remain locked.

Although you are not prompted to type a password in this mode, you can type either your power-on or administrator password anytime after POST has completed, even after the operating system has loaded. If you type a password, the keyboard will unlock, but the mouse connected to the mouse port will remain disabled.

The Off mode is useful for network servers and other computers that operate unattended. If a power failure occurs, the computer will automatically restart and resume operating in this mode when power is restored, without operator intervention.

54 Using Your Personal Computer

Dual In Dual mode, the startup behavior of the computer depends on whether

the computer is started from the computer power switch or by an unattended method, such as a modem, timer, or Wake on LAN.

If you start the computer by using the power switch, the computer operates the same as it does in the On mode. Refer to page 53 for further information.

If the computer is started by an unattended method, such as remotely over a LAN, the computer operates the same as it does in Off mode. Refer to page 53 for further information.

Note: Even though the mouse and keyboard are not active, the system

can still be managed remotely by network management software, such as TME 10 NetFinity or Intel LANDesk.

If both a power-on and administrator password are set, you can type either of the passwords at the password prompt that appears as you start your computer. However, if you want to change any settings in the Configuration/Setup Utility program, you must type your administrator password at the password prompt that appears when you try to access the Configuration/Setup Utility program. If you type your power-on password at this prompt, you will be able to view limited information in the Configuration/Setup Utility program, but you will not be able to change any settings.

The password does not appear on the screen as you type it. If you type the wrong password, you receive a screen message telling you so. If you type the wrong password three times, you must turn off the computer and start again. When you type the correct password, the keyboard and mouse will unlock, and the computer will begin normal operation.

Using Advanced Power Management Features

Your computer comes with built-in energy-saving capabilities. You can view and change energy-saving settings using the Advanced Power Management menu in the Configuration/Setup Utility program. This section describes the Advanced Power Management features in your computer and provides instructions for using these features.

Important

If a device, such as a monitor, does not have power-management capabilities, it can be damaged when exposed to a reduced-power state. Before you make energy-saving selections for your monitor, check the documentation that comes with your monitor to see if it supports Display Power Management Signaling (DPMS).

Automatic Hardware Power Management Features

With Automatic Hardware Power Management, you can have the computer, microprocessor, and monitor (if the monitor supports DPMS) go into reduced-power states if they are inactive for a certain length of time.

There are three levels of power management. For each level, you can specify the amount of time that the computer must be inactive before the power management options you select begin to take effect. For Level 1, you can select 5 minutes to 4 hours; for Level 2, you can select 10 minutes to 5 hours; and for Level 3, you can select 15 minutes to 6 hours. At each level, you can define the amount of energy savings by specifying values for the following options.

 System Power: With this option, you can select On if you want the computer

to remain on, or Off if you want the computer to shut down.

 Processor Speed: With this option, you can set your microprocessor to run at 1,

10, 25, or 50 percent of its internal clock speed, or you can disable the microprocessor entirely. Any computer activity returns the microprocessor to full speed.

System Management Settings

This section, which describes how to configure the network interface in your computer, is intended primarily for network administrators. For further information on the system management capabilities of your computer, refer to “Using System Management Features” on page 32.

The Configuration/Setup Utility program includes settings that can be enabled and disabled to configure the network interface in your computer. These settings are:

 Ethernet support

 Remote program load (RPL) and dynamic host configuration protocol (DHCP)  Automatic power on startup sequence  Wake on LAN  Update POST/BIOS from network

If you have an integrated Ethernet subsystem, you can also view the media access control (MAC) address for your computer in the Configuration/Setup Utility program. To access the MAC address, select Devices and I/O Ports from the Configuration/Setup Utility program menu, and then select Ethernet Setup. You can view but not change the MAC address setting.

Instructions for accessing the other system management settings in the Configuration/Setup Utility program follow.

Ethernet Support

This setting is used to enable or disable the integrated Ethernet controller in your computer. The setting is enabled by default.

If you do not use the integrated Ethernet, disable the Ethernet Support setting. By doing this, you free up system resources that can be used for optional adapters.

To access the Ethernet Support setting, select Devices and I/O Ports and then

Ethernet Setup from the Configuration/Setup Utility program menu. Note: The serial number for the system board integrated Ethernet is 10000000. You

might need this information if you install optional network adapters.

64 Using Your Personal Computer

RPL and DHCP

Remote program load (RPL) enables your computer to start directly from a server over a LAN that has been configured for RPL. Network-management software, such as LANClient Control Manager, is required to take advantage of RPL.

Dynamic host configuration protocol (DHCP) makes it possible for a DHCP server

on your intranet

to assign an internet protocol (IP) address to your computer so that a boot image can be remotely loaded. DHCP can be used by network-management software such as Intel LANDesk Configuration Manager.

Models with an integrated Ethernet subsystem are enabled to use RPL and DHCP as selected through the Configuration/Setup Utility program. A model without the integrated Ethernet can also use these features, but only if it is equipped with an optional network adapter that has built-in read-only memory (ROM) support for RPL or DHCP. See the documentation that comes with the optional adapter for more information.

If you install an optional network adapter with those models that have integrated Ethernet, disable Ethernet Support if you want to use the RPL or DHCP features of the optional adapter. See “Ethernet Support” on page 64 for information on disabling the integrated Ethernet subsystem.

To enable or disable RPL or DHCP, complete the following steps:

1. Start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility Program” on page 39).

2. Select Devices and I/O Ports from the Configuration/Setup Utility program menu, and then select Ethernet Setup.

3. Set Ethernet Support to Enabled.

4. Under Network Boot, use the arrow keys to select RPL or DHCP. (Select Disabled if you do not want to start an operating system from the network.)

5. Press Esc until you return to the Configuration/Setup Utility program menu.

6. Select Start Options, and then select Startup Sequence. You must include the Network setting somewhere in your startup sequence.

An intranet is a network within an organization that provides services similar to those provided by the

Internet, but that is not necessarily connected to the Internet.

Chapter 5. Using the Configuration/Setup Utility Program

7. Refer to “Exiting from the Configuration/Setup Utility Program” on page 43 for instructions on saving your settings and exiting from the Configuration/Setup Utility program.

Note: When you are using the RPL and DHCP features, you might encounter error

messages specific to the integrated Ethernet subsystem. If this happens, record the error message and report the problem to your network administrator. Also, information about these error messages is documented in “Error Messages Specific to the Integrated Ethernet” on page 107.

Network-Enabled Startup Sequence: If your computer is equipped with the

integrated Ethernet subsystem, the settings for the primary startup sequence have been factory-changed to support network-management software, such as LANClient Control Manager. If your computer is properly configured, you can use these settings to perform a remote program load each time your computer is started.

Note: These factory settings are not the default settings for your computer. If the

default settings are ever restored, the factory settings will be erased. (For the default settings, see “Default Settings for the Startup Sequence” on page 68.) If the default settings are loaded, you can always change these settings back to the values shown in the table below.

To view or change any of the startup sequence settings, select Start Options from the Configuration/Setup Utility program menu, and then select Startup Sequence. The primary startup sequence is the first group of startup devices that you see. The factory settings for these devices are listed below.

First Startup Device Diskette Drive 0 Second Startup Device Network (RPL) Third Startup Device Hard Disk Drive 0 Fourth Startup Device Disabled

As the above settings imply, once your computer is started (and there is no flash diskette loaded in the diskette drive), the computer tries to perform an RPL over a network. When this happens, the following message appears on the screen.

Press "Home" key to cancel RPL

If your computer is properly connected to a LAN, RPL will continue to run until it is successful or until you cancel it by pressing the Home key. If your computer is

Although RPL does not show up in this menu, this is the action (remote program load) that is taking

place when the second startup device is accessed. You can change this setting in the Ethernet Setup menu, under Network Boot. See “RPL and DHCP” on page 65 for more information.

66 Using Your Personal Computer

not connected to a LAN or if you cancel RPL, the computer accesses the third startup device, the hard disk drive, and attempts to load the operating system. Note that if you have enabled DHCP under Network Boot (in Ethernet Setup menu) instead of RPL, the following message also appears on the screen each time a network boot occurs.

Press "Spacebar" to Boot from Network

If your computer is properly connected to a LAN, you must press the spacebar to invoke DHCP. If the computer is not connected to LAN or if you cancel RPL by pressing the Home key, the computer bypasses DHCP and accesses the third startup device.

Important

If you do not plan to use the integrated Ethernet subsystem, disable it. For more information, see “Ethernet Support” on page 64. If you disable the integrated Ethernet, the RPL or DHCP message will not appear on the screen each time you start the computer.

If you see an error message associated with RPL or DHCP, refer to “Error Messages Specific to the Integrated Ethernet” on page 107 for more information.

Chapter 5. Using the Configuration/Setup Utility Program 67

Default Settings for the Startup Sequence: The default settings for the startup

sequence of your computer are shown below. Default settings differ between those computers that have integrated Ethernet and those computers that do not. To view or change any of the startup sequence settings, select Start Options from the Configuration/Setup Utility program menu, and then select Startup Sequence.

Automatic Power On Startup Sequence

When your computer is turned on remotely, the Automatic Power On Startup Sequence determines the order of the startup devices. The startup device is the device that will be used to load the operating system. The settings for the Automatic Power On Startup Sequence are used in conjunction with the automatic power on features in your computer, such as Serial Port/Modem Ring Detect, Wake on Alarm, and Wake on LAN.

To access the Automatic Power On Startup Sequence settings, select Start Options from the Configuration/Setup Utility program menu, and then select Startup

Sequence.

Wake on LAN

This setting is used to enable or disable the IBM-developed Wake on LAN feature, which makes it possible for your computer to be powered on remotely by a network administrator. Remote network-management software must be used to support Wake on LAN. Examples of such software are LANClient Control Manager and TME 10 NetFinity.

To access the Wake on LAN setting, select Advanced Power Management, and then select Automatic Power On from the Configuration/Setup Utility program menu.

Note: To use Wake on LAN with an optional network adapter, the adapter must

support Wake on LAN and be properly configured.

Update POST/BIOS from Network

When this feature is enabled, the POST/BIOS in your computer can be updated remotely by a network administrator. If you have set an administrator password for your computer, it does not have to be entered by the network administrator. Network management software is required in order to take advantage of this feature.

To access this setting, select System Security from the Configuration/Setup Utility program menu, and then select POST/BIOS Update.

Chapter 6. Solving Problems

Computer problems can be caused by hardware, software, or user error (for example, pressing the wrong key). Using the diagnostic aids discussed in this chapter, you might be able to solve such problems yourself or gather helpful information you can pass on to a service technician.

You can check the hardware by following the procedures in this chapter. You can also use the diagnostic programs provided with your computer (see “Diagnostic Programs” on page 104 for a description of these programs).

If the hardware checks out OK, and you have not made a user error, you might have a software problem. If you suspect that you have a software problem and your computer came with IBM-preinstalled software, refer to About Your Software and the operating system documentation that comes with your computer. If you have installed software applications yourself, consult the documentation that comes with the software.

Error Messages

Error messages that appear on the screen might be text, numeric, or both. There are several types of error messages:

 POST error messages

Messages that appear when POST finds problems with the hardware during startup or when a change in the hardware configuration is found. POST error messages are 3-, 4-, 5-, 8-, or 12-character alphanumeric messages and include brief explanations (except I999XXXX errors).

For more information about what caused an error message to appear and what action to take, refer to “Solving POST Problems” on page 74 and “POST Error Message Charts” on page 77.

 Software-generated error messages

Messages that appear if a problem or conflict is detected by the application program, the operating system, or both. Error messages for operating-system and other software problems are generally text messages, but they also can be numeric messages. For information about these software error messages, refer to the information that comes with the operating system or application program, or both.

 Diagnostic error messages

Messages that appear if a hardware problem is detected by a diagnostic test program. The messages present text information that can be used to identify a failing part.

 Integrated Ethernet-specific error messages

Messages that appear if a problem arises with the integrated Ethernet and the RPL or DHCP environments. These messages are specific to the integrated Ethernet controller and software code of your computer.

72 Using Your Personal Computer

Power-On Self-Test

Each time you turn on your computer, it performs a series of tests that check the operation of the base computer. This series of tests is called the power-on self-test (POST).

POST does the following:

 Checks basic system-board operations  Checks the memory operation  Compares the current system configuration with that established by the

Configuration/Setup Utility program

 Starts the video operation  Verifies that the diskette drives are working  Verifies that the hard disk drive and the CD-ROM (if installed) are working

As POST starts, numbers showing the amount of memory being tested appear in the upper-left corner of the screen until the total amount of memory in the system is reached. Options for running a fast POST or accessing the Configuration/Setup Utility program appear in the lower-left corner of the screen.

Note: The amount of available memory shown might be somewhat less than

expected because of basic input/output system (BIOS) shadowing in random access memory (RAM).

If POST finishes without detecting any problems, you will hear one beep and the first screen of your operating system or application program appears (if you have not set a power-on password). If you have set a power-on password, a password prompt appears. You must enter your password before the first screen of your operating system or application program will appear. (For further information on using passwords, refer to “Using Passwords” on page 53.)

If POST detects a problem, you will hear multiple beeps or no beep. In most cases, an error code appears in the top left corner of the screen, and in some cases a description of the error is displayed beside the code. (Note that the screen will sometimes display multiple error codes and descriptions.) For more information about what caused an error message to appear and what action to take, refer to “Solving POST Problems” on page 74 and “POST Error Message Charts” on page 77.

If you do not hear a beep during POST, refer to “Troubleshooting Charts” on page 96. You might need to have your computer serviced.

Chapter 6. Solving Problems 73

Solving POST Problems

If you receive an error message during the power-on self-test (POST), completing the steps outlined in this section might enable you to resolve the problem.

Note

If you have just added, removed, or changed the location of a device and you receive an error message, follow the procedure on page 44. If this does not eliminate the error message, proceed with the following instructions.

1. Write down all error code numbers and descriptions that appear on the screen as you start your computer. (Note that a single problem can cause several error messages to appear. When you correct the cause of the first error message, the other error messages probably will not appear on the screen the next time you turn on your computer.)

2. If you have set a power-on password, a password prompt appears. If you have set both power-on and administrator passwords, you can type either of the passwords at the password prompt. However, if you think you might need to change any settings in the Configuration/Setup Utility program, you must type your administrator password at the password prompt. If you type your power-on password, you will be able to view error codes and error code descriptions displayed on the POST Startup Errors screen, and you will also be able to view limited information in the Configuration/Setup Utility program. However, you will not be able to change any settings.

3. In the case of most errors, the Configuration/Setup Utility program starts automatically so that you can attempt to identify and correct the problem. When the Configuration/Setup Utility program starts, a screen labeled POST Startup Errors appears. (Note that the POST Startup Errors screen does not appear immediately. You must wait approximately one minute.) If the POST Startup Errors screen does not appear, proceed to step 6.

4. At the POST Startup Errors screen, select Continue if you want to access the Configuration/Setup Utility program menu. Select Exit Setup if you want to exit the Configuration/Setup Utility program. (See the Important text box in step 5 for information on exiting the Configuration/Setup Utility program without making any changes to current settings.) To select an item, press Up Arrow (↑) or Down Arrow (↓) to highlight the item, and then press Enter.

74 Using Your Personal Computer

5. If you selected Continue in step 4, the Configuration/Setup Utility program

menu appears on the screen. You will see a pointer next to any menu items that are malfunctioning or that have been changed since the last time you turned on your computer. If you did not knowingly make a change to a flagged menu item, there is likely a malfunction in that item. If you made a change, continue here. If you did not make a change, go to step 5e.

To use the Configuration/Setup Utility program, do the following:

a. Select the menu item that is flagged (or that you wish to view) by pressing

Up Arrow (↑) or Down Arrow (↓), and then press Enter.

b. A new menu specific to the item that you selected appears. Press Left

Arrow (←) or Right Arrow (→) to toggle between choices for a menu item. (Note that each menu item has a Help screen. To view the Help screen, select the menu item, and then press F1.)

c. When you have finished viewing and changing settings, press Esc to return

to the Configuration/Setup Utility program menu.

d. Before you exit from the program, select Save Settings. When you exit

from the Configuration/Setup Utility program menu (see step 5e), your operating system will start automatically (unless there is an unresolved problem with the IDE hard disk drive).

Important

If you did not change any settings in the Configuration/Setup Utility program, note the following:

 You will get an error message if you exit from the

Configuration/Setup Utility program without saving settings. Your operating system will not start, but the computer will automatically restart. When the computer restarts, you will get a POST error message, and then the Configuration/Setup Utility program will again start automatically.

 You will not get an error message if you select save the settings and

exit the Configuration/Setup Utility program. Your system will save all settings as they currently appear in the Configuration/Setup Utility program and your operating system will start (unless there is an unresolved problem with an IDE device).

e. To exit from the Configuration/Setup Utility program, press Esc and follow

the instructions on the screen.

 A hard disk or other IDE drive (such as an IDE CD-ROM drive) was

added or removed, but the changes to the Configuration/Setup Utility program have not yet been saved. Refer to page 44 for further information and instructions on saving the configuration.

 A hard disk or other IDE drive was added, but the master/subordinate

(slave) setting on the drive is improperly set.

 The power or IDE cable is disconnected or not fully seated.  A hard disk drive is failing.

Action: Verify that the Configuration/Setup Utility program correctly reflects the number of IDE drives installed (hard disk drives, CD-ROM drives, and so on). For more information, refer to Chapter 5, “Using the Configuration/Setup Utility Program” on page 39.

If the information is correct, save the settings, exit from the Configuration/Setup Utility program, and restart the computer.

If the information is not correct, do the following.

1. Exit from the Configuration/Setup Utility program without saving the settings.

2. Verify that the power cable and IDE cable are fully seated into the drive connectors, and the IDE cable is fully seated into the connector on the system board.

3. If you just added a new drive, verify that the drive you added has the master-subordinate (slave) setting set correctly. If the new drive is the only drive attached to the IDE cable, it must be set as the master. If it is the second drive on the IDE cable, it must be set as the subordinate.

Note: If you installed two new drives on the same cable, ensure that

one is set as a master and one is set as a subordinate.

See the instructions that came with your new drive for the jumper locations and settings.

4. Restart the computer. If the 1762 error message appears again, verify that the IDE drive information in the Configuration/Setup Utility program is correct. If it is correct, save the information and restart the computer. If the information is still incorrect, you might have a failing drive. Have the computer serviced.

1800 A PCI adapter has requested a hardware interrupt that is not available.

Action:

1. Make sure that all ISA legacy adapters are set correctly in the Configuration/Setup Utility program. If the hardware interrupt settings are not correct, change and save the settings. Setting the resources used by ISA legacy adapters to Not available enables the Plug and Play function to configure around the legacy adapters.

For background information on PCI, ISA, Plug and Play, and legacy (non-Plug and Play) adapters, refer to Installing Options in Your Personal Computer and Understanding Your Personal Computer. For information about required interrupt resource settings for ISA legacy adapters, refer to the documentation that comes with these adapters. For instructions on using the Configuration/Setup Utility program, see Chapter 5, “Using the Configuration/Setup Utility Program” on page 39.

2. Make sure that switches on all ISA legacy adapters are set correctly. For information about switch settings, refer to the documentation that comes with the ISA legacy adapters.

3. If all hardware interrupts are being used by ISA legacy adapters, you might need to remove an ISA legacy adapter to make an interrupt available to the PCI adapter you want to install. For instructions on removing adapters, see Installing Options in Your Personal Computer.

Note: If you remove an ISA legacy adapter, set the hardware interrupt

used by the removed adapter to Available before installing another adapter.

4. If you have other PCI or Plug and Play adapters installed, you might need to remove one of these adapters to make an interrupt available to the PCI adapter you want to install.

If the problem cannot be isolated and corrected, have the computer serviced.
