UnOfficial Asus Rampage II Extreme Thread

[trt740]

If you can't boot into DOS and use old style downgrade then I suggest you do the following :

1-Log into BIOS and force boot from BIOS 2
2-Backup BIOS 2 to BIOS 1
3-force boot with BIOS 1 which well be the same old version of BIOS 2
4- update BIOS 1 with 1504

I cannot use that procedure because I accidental copied the 1639 bios to both bios chips. I tried Afudos but the bios won't fit on a floppy and I tried using it with a usb drive that I made it bootable and it says bad file name when I type afudos /ibiosname

it appears that once I go over 4.0ghz the 1639 bios is over clocking my PCIE slot and effecting my video card. It tried setting the bus manually to 101 but it acts the same as the default 100. My screen goes crazy
