Undo BIOS update on ASUS motherboard?

[Eversmann06]

I recently got an SSD and installed windows 7 on it. Everything went fine and I started installing drives for my graphics card and such. Mind you that I had this motherboard for the last 2 years with no problems what so ever. So after all the drivers had been installed. I decided to check the Asus site to see if there were any updates for my motherboard. There was an update for the Bios which I downloaded the ROM. I have the M5A99X EVO (not r2.0) so it came with the AI Suite II. Using the AI Suite II, I used its Bios update software. It flashed successfully and I restarted the computer. After the computer restart what normal happens is that it shows the Asus logo 3 times then boots windows. When I restarted it froze at the 2nd Asus screen. I waited for a whole 10 minutes thinking it was updating or something. Then I turned off the and reset the CMOS by removing the battery. After that it worked but whenever a 2nd hard drive is plugged in or my external hard drive is plugged into the USB port. It freezes at the 2nd or 3rd Asus screen. I really regret updating the Bios and was wondering if I could please revert back to my previous Bios version.

As long as you are able to re-flash you can always just download the version you had before and install that.

So if I were to download the ROM of the previous version I had, I could flash to it? It would be a downgrade instead of an upgrade.

yes, technically a downgrade but if it fixes your problems do it

Yes. You probably wouldn't notice a difference between the two if the latest version worked properly anyways.
