4.1.2 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 al-
lows 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 1024 KB 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
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 alpha-
numeric 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
