5.1.1 ASUS EZ Flash utility

accessible by pressing <Alt> + <F2> during the Power-On Self Tests

(POST).

To update the BIOS using EZ Flash:

1. Visit the ASUS website (www.asus.com) to download the latest BIOS

file for the motherboard and rename the same to

P5R8L.BIN.

2. Save the BIOS file to a flash disk/floppy disk, then restart the system.

3. Press <Alt> + <F2> during POST to display the following.
