BIOS Update
To update the EFI image in DOS to a newer release, use the EFI binary image and a
BIOS update utility. One utility that can be used is the AFUDOS BIOS update utility,
also referred to as a BIOS flash utility, with a command line interface for MS-DOS.
This utility is available through AMI and can be accessed here.
4.1.1
Windows
Copy the AFUWIN.EXE executable file to any storage location accessible by the host
system and then run AFUWIN in a Windows DOS environment command prompt.
Basic Usage:
AFUWIN <BIOSROMIMAGE>.ROM /P (XXXX is the BIOS version to be flashed)
Your keyboard and mouse will be suspended during the burn process.
You can alternatively use the GUI version (see AMI documentation)
4.1.2
MS- DOS
Copy the AFUDOS.EXE executable file to any storage location accessible by the host
system and then run AFUDOS in a DOS environment command prompt.
Basic Usage:
AFUDOS <BIOSROMIMAGE>.ROM /P /C (XXXX is the BIOS version to be
flashed)
AFUDOS ROMFILE.ROM /P /B /N /C
for EFI BIOS update. These two versions are not cross compatible. Using afudos.exe
