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:
Main lename Extension name
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.

• Make sure that the oppy disk is not write-protected and has at least
1024KB free space to save the le.
