ASUS P4B533-M motherboard user guide
4-1
4.1 Managing and updating your BIOS
It is recommended that you save a copy of the motherboard’s original
BIOS to a bootable floppy disk in case you need to reinstall the original
BIOS later.
4.1.1 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> right after the Power-On Self
Tests (POST).
Follow these steps to update the BIOS using ASUS EZ Flash.
1. Download the latest BIOS file from the ASUS website (see ASUS
contact information on page x). Save the file to a floppy disk.
2. Reboot the computer.
3. To use EZ Flash, press <Alt> + <F2> right after POST to display the
following screen.
Write down the BIOS file name on a piece of paper. You need to type
the exact BIOS file name at the EZ Flash screen.
4. Insert the disk that contains the new BIOS file into the floppy drive. You
will receive the error message, “WARNING! Device not ready.” if you
proceed to step 5 without the disk in the drive.
The BIOS information in the above screen is for reference only. What
you see on your screen may not be exactly the same as shown.
