4.1.3 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:
• 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.
1. Copy the AFUDOS utility (afudos.exe) from the motherboard support DVD 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.
A:\>afudos /oOLDBIOS1.rom
Main filename Extension name
3. Press <Enter>. The utility copies the current BIOS file to the floppy disk.
A:\>afudos /oOLDBIOS1.rom
