2-4 Chapter 2: BIOS setup
2.1.3 AFUDOS utility
The AFUDOS utility allows you to update the BIOS 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 DVD to
the bootable oppy disk you created earlier.
2. Boot the system in DOS mode, then at the prompt type:
afudos /o[lename]
The [lename] is any user-assigned lename which consists of no more than
eight alphanumeric characters for the main lename and three alphanumeric
characters for the extension name.
A:\>afudos /oOLDBIOS1.rom
• Ensure that the oppy disk is not write-protected and has at least 1024KB
free space to save the le.
• The BIOS screens in this section are for reference only. The actual BIOS
screen displays may not be the same as shown.
(2) Enter the BIOS Setup utility, and then go to the Tools menu. Select EZ
Flash 2 and press <Enter> to enable it.
You can switch between drives by pressing
<Tab> before the correct le is
found. Then press <Enter>.
4. When the correct BIOS le is found, EZ Flash 2 performs the BIOS update
process and automatically reboots the system when done.
• This function can support devices such as USB ash disks and oppy disks
with
FAT 32/16
format and single partition only.
• Do not shut down or reset the system while updating the BIOS to prevent
system boot failure!
