BIOS Upgrade Utility

All servers have BIOS software in a flash (ROM) chip located on the main logic

board. This BIOS initializes hardware and boots the operating system when the

server is turned on. The BIOS also provides access to other services such as a

keyboard and disk drives.

You can upgrade the server's BIOS to future releases by executing the BIOS

upgrade utility (PHLASH.EXE) located in the BIOS upgrade kit. PHLASH.EXE and

BIOS upgrades are available on the Internet.

CAUTION:

A crisis recovery diskette should be created

before upgrading the server BIOS.

Also, when upgrading the BIOS, you must remove any video

expansion boards and enable the onboard VGA. In the rare

event that you might need to use the Crisis Recovery Diskette,

the server will require that the onboard VGA be used in this

mode.

Two switches and one BIOS option affect the result of executing the PHLASH.EXE

program:

BIOS Protection (SW1-1

) — This switch, located on the main logic board,

must be set to

Normal(off)

before you can upgrade the server’s BIOS.

Recovery Mode Switch (SW1-2)

— This switch, located on the main logic

board, must be set to

Recovery

so the server BIOS can enter “Recovery

Mode.”

System BIOS Flash (BIOS option)

— This BIOS option must be set to

Enable BIOS Upgrade

before you can upgrade the server’s BIOS.

If you are having trouble flashing the server’s BIOS, refer to Chapter 13,

“Troubleshooting.”
