2. download the older BIOS version you want to flesh, unzip and save it to C:\
3. start Asus Update, go to Options and select 'BIOS downgradeable" and save
4. choose "update BIOS from file" and point to the BIOS file that you downloaded
5. after it finishes, reboot and MAKE SURE that you correctly clear the CMOS!! (might have to wait for 10 or more minutes)
(if you dont do this you'll have problems on POST)
I succesfully use it to revert to 311 "best" OC bios so far!
good luck!
I have done this and it works fien on this and my X38 Maximus. However What about if using the AfuDOS method w/ switches? I noticed the current ROMs are too big for the floppy even though manuals calls for min of 1024kb, and files shows as 2mb.

The question then, is how do I make a Sony Memory Stick Pro Duo bootable to run Afudos to back up old BIOS or flash back to stable final? Do I use the real FDD and direct to USB (my PSP w/ MS pro duo)?
