Troubleshooting BIOS Problems
The BIOS is a set of program routines that gives the workstation its fundamental
operational characteristics. Many problems with your workstation can be solved by
updating (flashing) the BIOS (Basic Input Output System).
NOTE It is recommended that before you make any modifications to the BIOS you take note of
the system setup.
Updating The BIOS
The latest system BIOS (standard flash operation) for your workstation can be
downloaded from HP’s Support Web site at:
www.hp.com/go/workstationsupport .
Instructions on updating the BIOS are supplied with the downloaded BIOS files and a
BIOS flash utility.
Restoring BIOS Default Settings
Suspected hardware errors may be caused by BIOS and configuration issues. If the BIOS
settings are suspected to be wrong, do the following steps to restore the BIOS to its
default setting:
1. Press F2 while the initial HP logo is displayed immediately after restarting the
workstation to access the Setup program.
2. Press F9 to load the default settings from the Setup program.
3. Set the “Reset Configuration Data” to Yes in the Main menu.
