How to recover a corrupt BIOS on Crosshair V

post #1 of 3
Thread Starter 
so i FOUND this http://www.xtremesystems.org/forums/showthread.php?276706-Recovering-CHVF-from-bad-bios-flash-help


I tried to flash a new splash screen on my system through the MY logo crap on the AI SUITE... Warning this may brick your system!!! well. about 90% through the flash my system suddenly started running super super slow... as if the cpu was bogged down 100 % by some program.. I couldn't even use the mouse or keyboard anymore. I saw the the AI suite program closed, so my only option was to shut down the system.. Boom it was bricked. IF I would turn it on and let it sit for about 2 minutes, a prompt would appear saying something like " BIOS recovery warning" " looking for c5f.rom" then it sayd something about inserting the recovery cd, or a usb device with c5f.

I tried to insert the motherboard cd and reboot, but nothing happened.

Then I called ASUS.. and they were -negative 100% help. the guy said I need to RMA my board. I asked him at least 5 times if he was certain, and if he could ask anyone else if there was something I could do.. The end result was I told him Im not RMA ing my board through asus, Ill do Newegg.

Then used GOOGLE and found the link that I posted in the beggining of the thread.

SO .. What I did was: Insert my Asus motherboard cd that I got with the board, unplug all USB devices except LEAVE one keyboard attached. Then I unplugged all hard drives. I tried it again and it failed. Then I plugged my cd-rom drive into the sata port that was the farthest one to the bottom, and farthest one to the back of the board (not the port that is by itself).

Rebooted and then it loaded a recovery... I was able then navigate the cd and select the cf5.rom file, and flash the bios...

I then rebooted, and re flashed the current bios :1102"


all good now!!!

hope this helps one of you suckers trying to change your splash screen , or anyone who has a interrupted flash !

Nice, I was going to say stick the ROM on a USB stick of CD and see if the recovery can re-flash itself.

My friend just had a bad bios flash and this saved us quite a bit. However for those trying via a flash drive there is a trick to it. I found on other forums that you could do it via ROG Connect port however many refer to a button. This is what we did and it did work.

These instructions refer to a CrossHair V Formula (not one of the more expensive versions)
1) Make sure your flash drive is formatted as FAT32
2) Put the latest ROM file on the drive and name it C5F.ROM
3) Insert the flash drive into the ROG Connect port. Make to disconnect any other USB devices you have connected.
4) Ensure that the ROG Connect switch on the motherboard is set in the OFF position. This will allow the drive to get power during boot.
5) Boot the system and wait. The system may reboot but you will get video once it is done.
(If the drive has an activity light on it you should hear it beep shortly after the system beep)

If you didn't have a keyboard connected it will indicate one wasn't found and it will prompt you to press F1 to recover bios settings.

6) Enjoy!

P.S. - ASUS support had told us that we would need a new flash chip prior to finding this recovery method.
