5.1.3 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 filename 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.

A:\>afudos /oOLDBIOS1.ROM

• Make sure that the oppy disk is not write-protected and has at

least 600 KB free space to save the le.

• The succeeding BIOS screens are for reference only. The actual BIOS

screen displays may not be exactly the same as shown.

• This function can support devices such as USB ash disk, or oppy

disk with FAT 32/16 format only.

• Do not shut down or reset the system while updating the BIOS to

prevent system boot failure!

4. When the correct BIOS file is found, EZ Flash 2 performs the BIOS

update process and automatically reboots the system when done.

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.
