4.2 BIOS Update Utili
ty
The flash ROM contains system initialization routines, the BIOS Setup Utility, and runtime
support routines. The exact layout is subject to change, as determined by BIOS. The flash
ROM also contains initialization code in compressed form for onboard peripherals, like
SCSI, NIC and video controllers. The complete ROM is visible, starting at physical address
4 GB minus the size of the flash ROM device.
A 16-KB parameter block in the flash ROM is dedicated to storing configuration data that
controls the system configuration (ESCD). Application software must use standard APIs to
access these areas; application software cannot access the data directly.
BIOS Update Utility
Server platforms support DOS-based, Windows-based and Linux-based firmware update
utilities. This utility loads a fresh copy of the BIOS into the flash ROM.
The BIOS update may affect the following items:
The system BIOS setup utility and strings
Onboard video BIOS, RAID BIOS, and other option ROMS for the devices embedded
on the server board
Memory reference code
Microcode updates
