2.1.4 AFUDOS utility The AFUDOS utility allows you to update the BIOS file in DOS environment using a bootable floppy disk. 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. • Ensure that you prepare two floppy disks: the bootable floppy disk and the floppy disk containing the AFUDOS utility and the latest BIOS file. • Ensure that the floppy disk is not write-protected and has at least 1072KB to save the AFUDOS and BIOS files. • The succeeding BIOS screens are for reference only. The actual BIOS screen displays may not be the same as shown. Updating the BIOS file To update the BIOS file using the AFUDOS utility: 1. Insert the bootable floppy disk into the floppy disk drive to boot the system in DOS mode. 2. Replace the bootable floppy disk and insert the floppy disk that contains the AFUDOS utility and the latest BIOS file. • Obtain the AFUDOS utility (afudos.exe) from the bundled support DVD and the latest BIOS file from the ASUS website at www.asus.com. • We recommend that you write the BIOS filename on a piece of paper. You will need to key in the exact BIOS filename at the DOS prompt later. 3. At the DOS prompt, key in afudos /i[filename] where [filename] is the BIOS file in the floppy disk. A:\>afudos /iM3N78SE.ROM Press . Do not shut down or reset the system while updating the BIOS to prevent system boot failure! 5. The utility returns to the DOS prompt after the BIOS updating process is completed. Reboot the system from the hard disk drive. 2-4 Chapter 2: BIOS information
