2.1.4 Using ASUS EZ Flash to update the BIOS
The ASUS EZ Flash feature allows you to easily update the BIOS without having to
go through the long process of booting from a diskette and using a DOS-based
utility. The EZ Flash is built-in the BIOS firmware so it is accessible by simply
pressing <Alt> + <F2> during the Power-On Self Tests (POST).
To update the BIOS using ASUS EZ Flash:
1. Visit the ASUS website (www.asus.com) to download the latest BIOS file for your
motherboard. Save the BIOS file to a floppy disk.
2. Reboot the system.
3. To launch EZ Flash, press <Alt> + <F2> during POST to display the following.
4. Insert the floppy disk that contains the BIOS file. If all the necessary files are
found in the floppy disk, EZ Flash performs the BIOS update process and
automatically reboots the system when done.
