2.1.3 AFUDOS utility
The AFUDOS utility allows you to update the BIOS le in DOS environment using
a bootable oppy disk with the updated BIOS le. This utility also allows you to
copy the current BIOS le that you can use as backup when the BIOS fails or gets
corrupted during the updating process.
Copying the current BIOS
To copy the current BIOS le using the AFUDOS utility:
1. Copy the AFUDOS utility (afudos.exe) from the motherboard support CD to
the bootable oppy disk you created earlier.
2. Boot the system in DOS mode, then at the prompt type:
afudos /o[lename]
where the [lename] is any user-assigned lename not more than eight
alphanumeric characters for the main lename and three alphanumeric
characters for the extension name.
Main lename Extension name
A:\>afudos /oOLDBIOS1.rom
• Make sure that the oppy disk is not write-protected and has at least
1024KB free space to save the le.
• The succeeding BIOS screens are for reference only. The actual BIOS
screen displays may not be same as shown.
The utility returns to the DOS prompt after copying the current BIOS le.
3. Press <Enter>. The utility copies the current BIOS le to the oppy disk.
