operating system for the computer model and include device drivers supported by Windows
2000.
When prompted for the I386 directory on the operating system 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.

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.
2.1 Power-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 3.1for information
on setting, deleting, or bypassing the password.

DriveLock* Allows you to assign or modify a master or user password for
select IDE hard drives (not supported on SCSI hard drives).
When this feature is enabled, the user is prompted to provide
one of the DriveLock passwords during POST. If neither is
successfully entered, the hard drive will remain inaccessible
until one of the passwords is successfully provided during a
subsequent cold-boot sequence.
✎This selection will only appear when at least one drive that
supports the DriveLock feature is attached to the system.
This feature is supported on select models only. See the Desktop
Management Guide for more information.
Master Boot
Record Security*
Allows you to enable or disable Master Boot Record (MBR)
Security.
When enabled, the BIOS rejects all requests to write to the MBR
on the current bootable disk. Each time the computer is
powered on or rebooted, the BIOS compares the MBR of the
bootable disk to the previously saved MBR. If changes are
detected, you are given the option of saving the MBR on the
current bootable disk, restoring the previously-saved MBR, or
disabling MBR security. You must know the setup password if
one is set.
✎Disable MBR Security before intentionally changing the
formatting or partitioning of the current bootable disk.
Several disk utilities (such as FDISK and FORMAT) attempt to
update the MBR.
If MBR Security is enabled and disk accesses are being
serviced by the BIOS, write requests to the MBR are rejected,
causing the utilities to report errors.
If MBR Security is enabled and disk accesses are being
serviced by the operating system, any MBR change will be
detected by the BIOS during the next reboot, and an MBR
Security warning message will be displayed.
Save Master Boot
Record*
Saves a backup copy of the Master Boot Record of the current
bootable disk.
✎Only appears if MBR Security is enabled.
Restore Master
Boot Record*
Restores the backup Master Boot Record to the current bootable
disk.
✎Only appears if all of the following conditions are true:
MBR Security is enabled.
A backup copy of the MBR has been previously saved.
The current bootable disk is the same disk from which the
backup copy of the MBR was saved.
ÄRestoring a previously saved MBR after a disk utility or
operating system has modified the MBR may cause the data
on the disk to become inaccessible. Only restore a previously
saved MBR ifyou are confident that the current bootable
disk’s MBR has been corrupted or infected with a virus.
*Option supported on select models.
