Setup Utilities and Diagnostics Features
Setup Utilities (F10) and diagnostic features provide information needed about the computer system when contacting Customer Support. These tools can also be used to:
■Change factory default settings and to set or change the system configuration, which may be necessary when you add or remove hardware.
■Determine if all of the devices installed on the computer are recognized by the system and functioning properly.
■Determine information about the operating environment of the computer.
■Solve system configuration errors detected but not automatically fixed during the Power-On Self-Test (POST).
■Establish and manage passwords and other security features.
■Establish and manage energy-saving timeouts.
All features identified in this chapter may not be available on all HP products.
2.1Power-On Self-Test (POST)
POST is a series of diagnostic tests that runs automatically when the system is turned on. POST checks the following items to ensure that the computer system is functioning properly:
■Keyboard
■Memory modules
■Diskette drives
■All IDE and SCSI mass storage devices
■Processors
■Controllers
If the Power-On Password is set, a key icon appears on the screen while POST is running. You will need to enter the password before continuing. Refer to Chapter 3, Section 3.2 for information on setting, deleting, or bypassing the password.
If POST finds an error in the system, an audible and/or visual message occurs. For POST error messages and their solutions refer to Appendix C, “POST Error Messages.”

3.1Software Updating and Management
3.1.1 Dual-State Power Button
With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, the power button can function either as an on/off switch or as a suspend button. The suspend feature does not completely turn off power, 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.Left click on the Start Button, then select Control Panel > Performance and
Maintenance > Power Options.
2.In the Power Options Properties, select the Advanced tab.
3.In the Power Button section, select the desired power button setting.
After configuring the power button to function as a suspend button, 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.
ÄCAUTION: Do not use the power button to turn off the computer unless the system is not responding; turning off the power without operating system interaction could cause damage to or loss of data on the hard drive.
3.1.2Power Management
Power Management is a feature that saves energy by shutting down certain components of the computer when they are not in use, saving energy without having to shut down the computer.
With Advanced Configuration and Power Interface (ACPI) enabled for Windows XP, timeouts (the period of inactivity allowed before shutting down these components) can be enabled, customized, or disabled using the operating system.
1.In Windows XP, left click on the Start Button, then select Control Panel > Performance and Maintenance > Power Options.
2.In the Power Options Properties, select the Power Schemes tab.

3.2 Security
3.2.1 Password Security
The power-on password prevents unauthorized use of the computer by requiring entry of a password to access applications or data each time the computer is turned on or restarted. The setup password specifically prevents unauthorized access to Computer Setup, and can also be used as an override to the power-on password. That is, when prompted for the power-on password, entering the setup password instead will allow access to the computer.
A network-wide setup password can be established to enable the system administrator to log in to all network systems to perform maintenance without having to know the power-on password, even if one has been established.
3.2.2 Establishing a Setup Password Using Computer Setup
Establishing a setup password through Computer Setup prevents reconfiguration of the computer (use of the Computer Setup (F10) utility) until the password is entered.
1.Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the Computer.
2.Press the F10 key as soon as the monitor light turns green. Press Enter to bypass the title screen, if necessary.
If you do not press the F10 key at the appropriate time, you must turn the computer off, then on again, and press the F10 key again to access the utility.
3.Select Security, then select Setup Password and follow the instructions on the screen.
4.Before exiting, click File > Save Changes and Exit.
3.2.3Establishing a Power-On Password Using Computer Setup
Establishing a power-on password through Computer Setup prevents access to the computer when power is turned on, unless the password is entered. When a power-on password is set, Computer Setup presents Password Options under the Security menu. Password options include Password Prompt on Warm Boot. When Password Prompt on Warm Boot is enabled, the password must also be entered each time the computer is rebooted.
1.Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart the Computer.
2.Press the F10 key as soon as the monitor light turns green or the computer starts to boot. Press Enter to bypass the title screen, if necessary.
If you do not press the F10 key at the appropriate time, you must turn the computer off, then on again, and press the F10 key again to access the utility.

Ultra ATA Drive Guidelines and Features
4.1Ultra ATA Jumpers
Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on factory pre installed, replacement, or option drives. With cable-select, the drive is configured as either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
If you purchase a third-party hard drive, refer to the documentation included with the drive kit to ensure proper cable installation and configuration.
All drives on a controller channel need to have their jumpers either in the cable-select mode or have the individual drive jumper installed on the appropriate Master (Drive/Device 0) or Slave (Drive/Device 1) position.
4.2Ultra ATA Cables
When installing a second device on either the primary or secondary controller, you must use an industry standard 80-conductor Ultra ATA cable for optimal performance. These cables have a maximum length of 18 inches and a maximum distance of 6 inches between the two devices for a two-drive cable.
Drives operating at speeds faster than those of the Ultra ATA-33 devices require industry-standard 40-pin, 80-conductor cables to maintain the higher data transfer rates possible with the improved technology.
When using Ultra ATA-133, -100, -66, and slower -33 drives in the same system, each drive will operate at its appropriate data transfer rate.
4.2.1 Cable Layout
The faces of industry-standard cable connectors are color coded for easy recognition:
■System board connector = blue face
■Device 0 connector = black face
■Device 1 connector = gray face
The color code of an industry-standard cable is valid only if the drive’s jumper is in the cable-select position.

On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system board connector and the Drive/Device 1 connector is always the closest to the system board connector.
Some cables may be labeled “Drive 0” instead of “Device 0” and “Drive 1” instead of “Device 1”.
4.3Drive Installation Guidelines
Most computer system boards have two ATA (IDE) controller channels with a dedicated connector for each controller. One controller is designated as the primary and the other as the secondary controller.
Each of the two controllers can have up to two devices attached to it. Each computer system may therefore have a maximum of four ATA/ATAPI drives. All drives are connected to these controllers using an industry-standard 80-conductor cable.
The industry standard 1.44 MB diskette drive has its own separate channel and is not included as a part of the maximum four drives.
Any drive attached to a controller must have a drive designation. If only a single drive is connected to a controller and its jumper is in the cable-select position, it is designated as the Master Drive (Drive/Device 0) by its attachment to the Drive/Device 0 cable position. If two cable-selected drives are connected to a single controller, one will be designated by its attachment to the cable as the Master (Drive/Device 0) and the other as Slave (Drive/Device 1).
For optimal performance of a computer system, all drives need to be attached to the ATA controllers in a specified sequence. This sequence is determined by the device class of the drives and by specific attach sequence rules.

General Attach Guidelines
■The lower the device class number, the faster the device and the more bandwidth required.
■Drives installed in the Device 0 positions on both the primary and secondary controllers receive the greatest possible bandwidth.
■The bootable ATA hard drive should always be installed on the primary controller in the Device 0 position.
4.3.2Attach Sequence Rules by Class Priority
Drives should be attached in the sequence shown for optimum performance starting at position 1.

The lowest class drive - bootable hard drive recommended. |
|
|
2 |
If only two drives, the last drive goes here; otherwise the lowest class of the |

remaining drives. |
|
|
3 |
If only three drives, attach the final drive here. If a fourth drive exists, attach the |
|
lowest class drive here. |
|
|
4 |
If there is a fourth drive, attach the final drive here - the drive with the highest |
|
class number of all devices. |
*If there are three or more devices, two or more of which are hard drives, two hard drives should be attached to the primary controller first before following the General Attach Sequence Rule.
The rules allow for:
■Keeping the hard drive on a separate controller channel maximizes drive performance until a fourth device is added.
■Keeping the hard drives and removable media drives on separate controller channels maximizes compatibility.
■Keeping the hard drive and the writable optical drive on separate controller channels maximizes optical drive reliability.

4.3.4Additional Drive Application Notes
■When replacing a hard drive, the replacement should be of the same type (Ultra ATA -33, -66, or -100) as that being removed to retain the same level of performance.
■When Ultra ATA and SCSI hard drives are mixed in the same system, the Ultra ATA drive will become the boot drive unless the boot order is changed in Computer Setup (F10 Setup).
4.4 SMART
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers have built-in drive failure prediction that warns the user or network administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.
