[QUOTE=mikeyakame;3663860]You can't period. Only way to go back to older bios is through ms dos flashing tool AFUDOS and you have to boot from MSDOS floppy/flash drive to do that.

I used the Asus update tool to downgrade the bios.Just open it up and choose options in the drop down menu.Then click next, put a check mark in BIOS downgradable.Click next again.Now choose update bios from a file and click next.Then it will work.
