Flash 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 Intel. A 64 KB user
block is available for user ROM code or custom logos. The flash ROM also contains initialization
code in compressed form for onboard peripherals, like SCSI, NIC and video controllers. It also
contains support for the rolling single-boot BIOS update feature.
The complete ROM is visible, starting at physical address 4 GB minus the size of the flash ROM
device. The Flash Memory Update utility loads the BIOS image minus the recovery block to the
secondary flash partition, and notifies the BIOS that this image should be used on the next
system re-boot. Because of shadowing, none of the flash blocks are visible at the aliased
addresses below 1 MB.
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.

Rolling BIOS and On-line Updates

The Online Update nomenclature refers to the ability to update the BIOS while the server is
online and in operation, as opposed to taking the server out of operation while performing a
BIOS update. The rolling BIOS nomenclature refers to the capability of having two copies of
BIOS: the current one in use, and a second BIOS to which an updated BIOS version can be
written. When ready, the system can roll forward to the new BIOS. In case of a failure with the
new version, the system can roll back to the previous version.
