NSTALLING THE OPERATING SYSTEM

Depending on the model, Microsoft Windows 95, 98, or Microsoft Windows NT is preinstalled on the computer and will be configured automatically the first time the computer is turned on.

CAUTION:

successfully installed. Doing so may cause errors and may prevent the operating system from installing properly.

CAUTION:

PROCESS IS COMPLETE. Turning off the computer during the installation process might damage the software that runs the computer.

Do not add optional hardware devices to your computer until the operating system is

Once the automatic installation has begun, DO NOT TURN OFF THE COMPUTER UNTIL THE

1.1 Microsoft Windows 95 or 98

The first time the computer is turned on, Microsoft Windows is automatically installed. This takes approximately 5 to 15 minutes, depending on the system hardware configuration. At the beginning of the installation process, the user is prompted to select the appropriate language for the operating system. Read and follow the instructions that appear on the screen to complete the installation.

When the Welcome to Windows screen is displayed, Internet Explorer is installed and the installation process is completed.

1.2 Microsoft Windows NT Workstation 4.0

The first time you turn on your computer, Microsoft Windows NT Workstation is automatically installed for you. This takes approximately 30 minutes, depending on the system hardware configuration. At the beginning of the installation process, the user is prompted to select the appropriate language for the operating system. Read and follow the instructions that appear on the screen to complete the installation.

1.2.1 Installing Windows NT Workstation 4.0 over a Network

Network installation is used primarily for installing or upgrading Microsoft Windows NT Workstation over a local area network. It can also be used to install additional drivers or files with Windows NT.

✎

This installation method should be used to deploy Windows NT using a distribution share point over a network connection.

This capability does not imply the grant of a site license for Microsoft Windows NT Workstation and should only be used to install the operating system on computers for which the appropriate software license has already been obtained.

Deskpro Service Reference Guide

1-1

The initial Windows NT installation (completed when the computer is first turned) on creates an I386 directory. This directory and its subdirectories provide the Compaq-specific integration of Windows NT for the computer model. This image, license permitting, can be used as a distribution share point to deploy Windows NT over a network connection.

To use a distribution share point to install or upgrade Windows NT, see the Windows NT Resource Kit and its documentation.

1.2.2 Installing or Upgrading Device Drivers

To install hardware devices such as a printer, a display adapter, or network adapter after the Windows NT installation is completed, Windows NT needs access to the appropriate software drivers for the devices.

The I386 directory and its subdirectories provide the Compaq-specific integration of Windows NT for the computer model and include device drivers supported by Windows NT.

When prompted for the I386 directory on the Windows NT CD, replace the path specification with C:\I386 or use the browse button of the dialog box to browse the computer for the I386 folder. This points Windows NT to the appropriate drivers and allows installation of the device to be completed.

1.2.3 Creating an Emergency Repair Diskette

✎

After installing Microsoft Windows NT, Compaq recommends that you create an Emergency Repair Diskette. Using one blank, formatted diskette, complete the following steps:

1. Click Start Æ Compaq Information Center Æ Create Emergency Repair Diskette.

2. Read and follow the instructions that appear on the screen. A set of boot diskettes should also be created. These diskettes are required to start the computer

should the Emergency Repair Diskette be needed. To create boot diskettes, you need three blank, formatted diskettes.

1. Click Start Æ Compaq Information Center Æ Create Boot Diskettes.

2. Read and follow the instructions that appear on the screen.

The following section applies only to computers equipped with a diskette drive.

1.2.4 Using the Emergency Repair Diskette

✎

To use the Emergency Repair Diskette if the computer is not equipped with the LS-120 drive, insert the first boot diskette in the diskette drive and restart the computer. Follow the instructions displayed on the screen.

To use the Emergency Repair Diskette if the computer is equipped with the LS-120 drive, follow the instructions below:

1. Restart the computer using the Microsoft Windows NT Boot Disk 1.

The following section applies only to computers equipped with a diskette drive.

1-2

2. Press the F6 key when the message “Setup is inspecting your computer’s hardware

configuration…” appears on your screen.

3. When asked if you want to specify a storage device, press S and select the Compaq

ATAPI/IDE/LS-120 Controller from the list.

4. When asked again if you want to specify a storage device, press the Enter key. Follow the rest of

the installation procedures as outlined in the operating system documentation from Microsoft.

1.3 Registering the Computer

The computer should be registered with Compaq. Registration establishes a record of ownership and gives the user an opportunity to receive product announcements, updates, and other communications periodically. To register one machine, just visit Compaq’s Web site at www.compaq.com/products/registration and follow the instructions that appear on the screen. To register more than one machine, either telephone in the information or enter the units one at a time on the Compaq Web site.

3.3 Fault Notification and Recovery

Fault Notification and Recovery features combine innovative hardware and software technology to prevent the loss of critical data and minimize unplanned downtime.

When a fault occurs, the computer displays a Local Alert message containing a description of the fault and any recommended actions. You can then view current system health by using Compaq Insight Personal Edition. If the computer is connected to a network managed by Compaq Insight Manager or other SNMP-based management products from Compaq Management Solutions Partners, the computer also sends a fault notice to the network management application.

3.3.1 Processor Fault Prediction and Prefailure Warranty

When the processor encounters an excessive number of error checking and correcting (ECC) cache memory errors, the computer displays a Local Alert Message. This message contains detailed information about the faulty processor, allowing you to take action before you experience non-correctable cache memory errors. The Prefailure Warranty allows you to replace these processors, free of charge, before they actually fail. Processors with ECC cache memory are available on select Compaq personal computers.

Deskpro Service Reference Guide

3-7

3.3.2 SMART Hard Drive Fault Prediction

The SMART hard drive monitors hard drive activity to predict failures and, in some cases, fix faults before failures occur. Fault prediction and failure indication parameters, such as abnormal variations in spinup and seek times, or non-correctable read and write errors, are tracked to determine the hard drive condition. Should these errors become significant, the computer displays a warning message. The warning gives you time to back up the hard drive and replace it prior to experiencing downtime or loss of data. The Prefailure Warranty for SMART hard drives allows you to replace these drives, free of charge, before the drives fail.

SMART hard drives are compliant with the Small Form Factor Committee Specification for SelfMonitoring, Analysis, and Reporting Technology (SMART). SMART is the industry standard technology, pioneered by Compaq and originally called IntelliSafe, that allows you to prevent data loss and minimize downtime, in concert with Compaq Insight Management Agents.

3.3.3 Drive Protection System

The Compaq Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in select Compaq Deskpro computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive replacement. When Compaq Deskpro Computers are built, each installed hard drive is tested using DPS and a permanent record of key information is written onto the drive. Each time DPS is run, test results are written to the hard drive. You can use this information to help diagnose conditions that caused you to run the DPS software.

3.3.4 Ultra ATA Integrity Monitoring

Ultra ATA Integrity Monitoring monitors the integrity of data as it is transferred between an Ultra ATA hard drive and the system’s core logic. If the computer detects an abnormal number of transmission errors, the computer displays a Local Alert message with recommended actions. An alert is also sent over the network to the system administrator.

3.3.5 ECC Fault Prediction and Prefailure Warranty

When the computer encounters an excessive number of error checking and correcting (ECC) memory errors, the computer displays a Local Alert message. This message contains detailed information about the errant memory module, allowing you to take action before you experience non-correctable memory errors. The Prefailure Warranty for ECC memory modules allows you to replace these modules, free of charge, before the modules actually fail. ECC memory modules are optional on all Compaq personal computers.

✎

To use this feature, you must replace the standard DIMMs with ECC DIMMs.

3.3.6 Surge-Tolerant Power Supply

An integrated surge-tolerant power supply provides greater reliability when the computer is hit with an unpredictable power surge. This power supply is rated to withstand a power surge of up to 2000 volts without incurring any system downtime or data loss.

Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote Compaq desktop personal computers, directly from the centralized network management console. Enabling the system administrator to perform this task remotely, on multiple computers, results in a consistent deployment of and greater control over Compaq desktop ROM images over the network. It also results in greater productivity and lower total cost of ownership.

FailSafe Boot Block ROM

The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash failure, for example, if a power failure occurs during a ROM upgrade. The Boot Block is a flashprotected section of the ROM that checks to validate the system ROM each time power to the system is turned on.



If the system ROM is valid, the system starts normally.



If the system ROM fails the validation check, the FailSafe Boot Block ROM provides enough support to start the system from a ROMPaq diskette, which will program the system ROM with a valid image.

Because there is no video or hard drive support from the Boot Block ROM, the keyboard lights communicate information. When the Boot Block detects an invalid system ROM, the system sounds a series of beeps (one long and three short) and flashes the three keyboard lights.

To recover the system after hearing the FailSafe Boot Block beeps, complete the following steps:

1. Remove any diskettes from the diskette drive and turn off the power.

2. Insert a ROMPaq diskette into the diskette drive.

3. Turn on power to the system. If a setup password has been established, the Caps Lock light will turn on.

4. Enter the setup password. If the system successfully starts from the diskette and successfully reprograms the ROM, then

the three keyboard lights will turn on. A “rising tone” series of beeps also signals successful completion.

3.4.4 Replicating Original Setup

This procedure gives an administrator the ability to easily copy one setup configuration to other computers of the same model. This allows for faster, more consistent configuration of multiple computers. To replicate your setup:

1. Access the Computer Setup Utilities menu.

2. Click File Æ Save to Floppy. Follow the instructions on the screen.

3. To replicate the configuration, click File Æ Restore from Floppy, and follow the instructions on the screen.

3.4.5 Dual-State Power Button

In Windows 95 or Windows 98, the power button can function either as an on/off switch or as a suspend button. The suspend feature does not turn off power altogether, but instead causes the computer to enter a low-power standby. This allows you to quickly power down without closing applications and to quickly return to the same operational state without any data loss.

To change the power button’s configuration, complete the following steps:

1. Access the Computer Setup Utilities menu.

2. Select Power Æ Energy Saver Options. Set the power button configuration to either Advanced or Minimal Energy Saver, or Disabled, as desired.

2.1.2, “Using Computer Setup Utilities.”

3. Select File Æ Save Changes and Exit.

After configuring the power button to function as a suspend button (Energy Saver mode), press the power button to put the system in a very low power state (suspend). Press the button again to quickly bring the system out of suspend to full power status. To completely turn off all power to the system, press and hold the power button for four seconds.

✎

If you have selected the “Blink LED during Energy Save” option in Computer Setup, the power-on light will blink once every second while the computer is in suspend. Refer to Section 2.1.1, “Using Computer Setup Utilities” for more information.

3.4.6 Power Management

Use the Timeouts option under the Power menu in Computer Setup to enable, customize, or disable standby timeouts. This feature shuts down certain components of the computer when they are not in use, saving energy without having to shut down the computer.

✎

When using Windows 95 or Windows 98, disable monitor timeouts in Computer Setup first, then establish the settings in Windows, to avoid potential conflicts.

Use Display Properties to establish, modify, or disable Power Management settings for the monitor. To access Display Properties, right-click on the Windows Desktop, then choose Properties.

ARD DRIVES

Compaq Computer Corporation uses IDE hard disk drives that conform to two different primary/secondary implementations. These are Conner mode and ATA-compatible mode. These two modes are incompatible with one another.

Device 0/Device 1 Relationship

A device 0/device 1 relationship exists when there are two hard drives connected to a single port. In this situation, one drive must be designated as the device 0 or primary drive and the other as the device 1, or secondary drive. This designation is necessary because both drives cannot work simultaneously.

SMART

The SMART IDE hard drives for the Compaq Deskpro Personal Computers have built-in drive failure prediction that warns the user or the network administrator of an impending failure or crash of the hard drive.

Automatic Soft-Drive Types

An automatic soft-drive type is a mechanism where the system ROM and Computer Setup automatically build a soft-drive type to provide support for IDE hard drives that are not in the hard drive parameter table.

The soft-drive types are assigned according to the table below:

Drive Hard Drive Type Controller

0 1

For hard drives that are greater than 528 MB, the system automatically translates the hard drive parameter for DOS by logically halving the cylinders and doubling the heads. This allows DOS to access greater than 528 MB. The translated hard drive parameters are put into the hard drive parameter table in the shadow RAM copy of the system ROM. When using any operating system other than DOS, you must use F10 Setup to set up the hard drive parameter table without translation.

Hard Drive

This section identifies some quick checks for hard drive-related problems. The information provided by the diagnostics tests includes: error code, system serial number,

drive serial number, drive model, and drive firmware revision. Specific details of the drive failure are not included.

When you run the diagnostics, the test results are stored in a log. After completing the test, you can print this log to a local printer or save it to a file. Alternatively, before running the test, you can configure the test options to send the results to a local printer or file.

Solutions for some typical hard drive problems are presented in the following table:

Problem Possible Solution

Hard drive error occurs. Hard disk has bad sectors or has failed. Use a utility to locate and

block usage of bad sectors. If necessary, reformat the hard disk.

Disk transaction problem. Either the directory structure is bad or there is a problem with a file. In

Windows 95 and 98, run ScanDisk. Click Start Æ Programs Accessories Æ System Tools Æ ScanDisk.

In Windows NT, right click Start, click Explore, and select a drive. Select File Æ Properties Æ Tools. Under Error-checking, click Check Now.

Drive not found. 1. Cable could be loose. Check cable connections.

2. The system may not have automatically recognized a newly installed device. See reconfiguration directions in the “Hardware Installation Problems” section. If system still does not recognize the new device, check to see if the device is listed within Computer Setup. If it is listed, the probable cause is a driver problem. If it is not listed, the probable cause is a hardware problem.

3. Check drive jumper settings. If the drive is a secondary drive that has just been installed on the same controller as the primary drive, verify that the jumpers for both drives are set correctly.

F-6

Nonsystem disk message. 1. The system is trying to start from a diskette that is not bootable.

Remove the diskette from the diskette drive.

2. The system is trying to start from the hard drive but the hard drive may have been damaged. Insert a bootable diskette into the diskette drive and restart the computer.

3. Diskette boot has been disabled in Computer Setup. Run Computer Setup and enable diskette boot.

Second Ultra ATA hard drive does not perform optimally.

Troubleshooting Without Diagnostics

The cable is not compatible with the drive type. Reinstall the second Ultra ATA hard drive using an 80-conductor cable.

Hardware Installation

You may need to reconfigure the computer when you add or remove hardware, such as an additional diskette drive. If you install a Plug and Play device, Windows 95 and 98 automatically recognizes the device and configures the computer. If you install a non-Plug and Play device, you must reconfigure the computer after completing installation of the new hardware. In Windows 95 and 98, select the Add New Hardware icon in the Control Panel and follow the instructions that appear on the screen. To reconfigure the computer in Windows NT Workstation 4.0 after installing new hardware, use the utility provided with the hardware.

Problem Possible Solutions

A new device is not automatically recognized as part of the computer system.

1. The computer needs to be reconfigured to recognize the new device. Follow the reconfiguration instructions above. If system still does not recognize the new device, but the device is listed within Computer Setup, use Computer Setup to address any resource conflicts.

2. When the system advised you of changes to the configuration, you did not accept them. Reboot the computer and follow the instructions for accepting the changes.

3. A Plug and Play board may not automatically configure when added if the default configuration conflicts with other devices. Use Windows 95 or 98 Device Manager to deselect the automatic settings for the board and choose a basic configuration that doesn’t cause a resource conflict. You can also use Computer Setup to reconfigure or disable devices to resolve the resource conflict.

4. The cables for the new external device are loose or the power cables are unplugged. Check all cables, and check that pins in the cable or connector are not bent down.

5. The power switch for the new external device is not turned on. Turn off the computer, turn on the external device, and then turn the computer on to integrate the new device with the computer.

6. If the drive is a secondary drive that has just been installed on the same controller as the primary drive, verify that the jumpers for both drives are set correctly.

Network

Some common causes and solutions for network problems are listed in the following table. These guidelines do not discuss the process of debugging network cabling.

Problem Possible Solution

The Remote Wakeup feature is not functioning.

1. The feature is not available when using an AUI network connection; use an RJ-45 network connection.

2. Remote Wakeup is not enabled. Use the network control application to enable Remote Wakeup.

Network driver does not detect network controller.

Network status link light does not turn on or flashes.

Diagnostics reports a failure. 1. The cable is not securely connected or is attached incorrectly.

Network controller is disabled. Run Computer Setup and enable network controller.

1. No active network is detected. Check cabling and network equipment for proper connection.

2. Network connection is not set up properly. Use the network control application to verify that the device is working properly.

3. System is configured for AUI connection; link LED does not apply to AUI connections.

4. Network driver is not properly loaded. Reinstall network drivers.

5. System cannot autosense the network. Disable autosensing capabilities and force the system into the correct operating mode.

Ensure that the cable is securely attached to the network connector and that the other end of the cable is securely attached to the correct device.

2. There is a problem with the cable or a device at the other end of the cable. Ensure that the cable and device at the other end are operating correctly.

3. The network controller is defective. Replace the controller or the system board.

4. Network controller interrupt is shared with an expansion board. Under the Computer Setup Advanced menu, change the resource settings for the board.

F-10

Diagnostics passes, but the computer does not communicate with the network.

Troubleshooting Without Diagnostics

1. Network drivers are not loaded, or driver parameters do not match current configuration. Make sure the network drivers are loaded and the driver parameters match the configuration of the network controller.

2. The network controller is not configured for this computer. In Windows 95, 98, or Windows NT, select the Network icon at the Control Panel.

3. Network controller interrupt with an expansion board. Under the Computer Setup Advanced menu, change the resource settings for the board.

Problem Possible Solution

Network controller stopped working when an expansion board was added to the computer.

1. Network drivers are not loaded or driver parameters do not match the current configuration. Make sure that the drivers are loaded and that the driver parameters match the configuration of the network controller.

2. The cable is not securely connected or is attached incorrectly. Ensure that the cable is securely attached to the network connector and that the other end of the cable is securely attached to the correct device.

3. Network controller interrupt is shared with an expansion board. Under the Computer Setup Advanced menu, change the resource settings for the board.

4. Network drivers were accidentally deleted when the drivers for the new expansion board were installed, or the files containing the network drivers are corrupted. Reinstall the network drivers, using backup diskettes.

Network controller stopped working without apparent cause.

Cannot connect to the network server when attempting Remote System Installation.

1. The files containing the network drivers are corrupted. Reinstall the network drivers, using backup diskettes.

Resolving Audio Hardware Conflicts

Hardware conflicts occur when two or more peripheral devices contend for the same signal lines or channels. Conflicts between the audio interface and another peripheral device may be due to the settings of the base I/O addresses, interrupts, or DMA channels. The audio interface typically has the following settings:

Item Setting

Base I/O address 220H FM Synthesizer I/O address 388-38Bh Interrupt IRQ 5 8-bit DMA Channel 1

To resolve hardware conflicts:

Change the hardware settings of your audio card or the peripheral card in your system if the

1. peripheral card is using the audio interface setting. You can change settings for integrated audio using Computer Setup.

If you are unsure of the settings of the peripheral cards, you can isolate the source of the

2. problem by temporarily removing all cards and other essential cards such as the disk controller. After that, add the cards back one at a time until the card that is causing the conflict is found.

Problem Possible Solution

Sound does not come out of the speaker.

Software volume control is turned down electronically, or CD-ROM volume control on the front or back of the computer is turned down.

Double click on the speaker icon located on the taskbar, then set the volume by adjusting the volume slider.

Troubleshooting Using Compaq Intelligent Manageability Features

The Local Alert Pop-Up Dialog notifies you of an impending or actual hardware failure. If the computer is connected to a network and the Compaq Insight Management Agents are installed and configured, an Simple Network Management Protocol (SNMP) trap (message) is sent to the specified SNMP-compliant management application.

The Local Alert Pop-Up Dialog also tells you the steps you need to take prior to a hardware failure to avoid loss of data and damage to the computer. The system administrator can create a customized action message that might include contact telephone or pager numbers.

To close the Local Alert Pop-Up Dialog, click the Close button. To retrieve fault information after closing the dialog, run Compaq Insight Personal Edition.
