5. At the prompt, “Please Enter File Name for NEW BIOS: _”, type in the BIOS file name that you downloaded from the ASUS website, then press <Enter>. EZ Flash will automatically access drive A to look for the file name that you typed.
2.1.2 Using AFLASH to update the BIOS Creating a bootable disk AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup.
BIOS revision will solve your problems. Careless updating may result to more problems with the motherboard! 1. Download an updated ASUS BIOS file from the Internet (WWW or FTP) (see ASUS CONTACT INFORMATION on page viii for details) and save to the boot floppy disk you created earlier.
