Hi guys,

I recently bought a Sabertooth x79 mb, which installed with the a very earlier factory bios, 0607 or version number like that. My problem is that I couldn't have my e5 2687w CPU works with that bios, I need to upgrade the mb bios to 4502 for support that CPU.

So, I think the right way to do that is firstly upgrade the bios to .CAP bios format by use the ASUS BIOS Converter and also to the 2002 version. However, since I couldn't boot my system, the only method I have is to use the USB BIOS Flashback function to make that work. So I copied the BIOS Converter .ROM to usb disk, renamed the file and plugged usb into the flashback usb slot and then pressed the flash button. Everything works fine until this step:

"After the system reboots twice, the .CAP conversion process is done."

How the hell am I supposed to do that? Since I couldn't have my system boot, and that's exactly why I flash the bios. Does anyone have any idea how to make that work? It's driving me crazy.

Thanks in advance.
