5.1.3 ASUS EZ Flash utility
The ASUS EZ Flash feature allows you to update the BIOS without having
to go through the long process of booting from a floppy disk and using
a DOS-based utility. The EZ Flash utility is built-in the BIOS chip so it is
accessible by pressing <Alt> + <F2> during the Power-On Self Tests
(POST).
4. Insert the floppy disk that contains the BIOS file to the floppy disk
drive. When the correct BIOS file is found, EZ Flash performs the BIOS
update process and automatically reboots the system when done.
To update the BIOS using EZ Flash 2:
1. Download the latest BIOS file from ASUS website (www.asus.com), or
obtain it from the support CD.
2. Save the BIOS file to a floppy disk, then boot the system from floppy
disk.
