5-4 Chapter 5: BIOS setup
5.1.3 AFUDOS utility
The AFUDOS utility allows you to update the BIOS file in DOS environment using
a bootable floppy disk with the updated BIOS file. This utility also allows you to
copy the current BIOS file 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 file using the AFUDOS utility:
1. Copy the AFUDOS utility (afudos.exe) from the motherboard support CD to
the bootable floppy disk you created earlier.
2. Boot the system in DOS mode, then at the prompt type:
afudos /o[filename]
where the [filename] is any user-assigned filename not more than eight
alphanumeric characters for the main filename and three alphanumeric
characters for the extension name.
Main filename Extension name
A:\>afudos /oOLDBIOS1.rom
• Make sure that the floppy disk is not write-protected and has at least
1024KB free space to save the file.
• 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 file.
3. Press <Enter>. The utility copies the current BIOS file to the floppy disk.
A:\>afudos /oOLDBIOS1.rom
