Flash Architecture and 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 64KB user
block is available for user ROM code or custom logos. The flash ROM also contains initialization
code in compressed form for onboard peripherals, such as 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.
A 16KB 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.
6.6.1
Flash Update Utility
Server platforms support a DOS-based firmware update utility. 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 utility and strings
Embedded device option ROMs
OEM binary area
Microcode updates
6.6.1.1
Flash BIOS
The BIOS flash utility is compatible with EFI, DOS, Microsoft* Windows* 2000 / 2003 / XP, and
Linux operating environments.
An
afuXXX
AMI Firmware Update utility (such as
afudos
,
afuwin
,
afulnx,
or
afuefi
) is
required for a BIOS update.
The format and usage of the
afuXXX
utility is as follows:
afuXXX /i<ROM filename> [/n] [/p[b][c]] [/r<registry_path>] [/s]
[/q] [/h]
/n
- don't check ROM ID
/pbc -
b - Program Boot Block
c - Destroy System CMOS
/r
- registry path to store result of operation (afuwin only)
/s
- Leave signature in BIOS
/q
- Silent execution
/h
