BIOS

3.2. BIOS Update Utility

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 stor-
ing 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, including the recovery code, setup util-

ity and strings.
Onboard video BIOS, RAID BIOS, and other option

ROMS for the devices embedded on the server board.
Memory reference code.

Microcode updates.

ME Firmware

Recovery Mode
Recovery process can be initiated by setting the recovery
jumper. BIOS would detect the recovery jumper set and start to
execute recovery code.
The BIOS consists of three parts, the Main BIOS Section, the
NVRAM Section, and the Boot Block Recovery Section. The
Main BIOS Section and the NVRAM Section will be updated
during recovery process, but the Boot Block will be preserved.
A BIOS recovery can be accomplished from a USB mass stor-
age device that includes the BIOS image file S2J_BIOS.CAP.
