Has anyone with this board updated to the new F5 bios? I been reading on other forums that it no good and has killed some boards.

I can confirm that the F5 BIOS for the X48T that was released a few days ago will brick your machine. Do not under any circumstances attempt to flash your BIOS to this version.

I tried to flash from F4 to F5 this morning using their @BIOS utility downloaded that same morning. I had an endless stream of errors (something along "Alloc kernel errors" ). The flash was totally corrupt. After a reboot and a bit of work (resetting CMOS, etc) I was able to recover to a working BIOS automatically.

I then made a second decision to re-attempt a flash to F5 using their FLASHSPI utility and a DOS boot disc. The flash completed successfully, but the machine would not POST. It entered a re-start loop with a long error beep. Resetting CMOS, taking out the battery for 30 minutes... nothing helped. Putting the recovery CD into the CD drive didn't help (apparently part of the Quad-BIOS recovery process involves BIOS images stored on the HDD or CDROM).

Anyways... I am livid! Going to RMA Monday morning and raise some hell with Gigabyte, especially if they give me any grief about BIOS flashing not being under warranty. I just spent $330 on their enthusiast-level board.. I demand satisfaction. This is completely inexcusable.

Got the same problem... quad bios is a fraud
creepster if you find a solution plz post it
Im still looking for a solution

I have found no solutions. From all of the forums I have read that deal with this issue, none have found any fixes. It seems that the only solution is to RMA the board to have it re-flashed under a warranty repair.

Assuming you are in the US, go to the US support page and submit an RMA request.

My RMA was issued within 1 hour.

I am really upset at how badly Gigabyte screwed this up. Call them up at 1-626-854-9338 and let them know you are mad too. Ask them to expedite your repair. It is completely inexcusable how they would release a BIOS that would kill so many motherboards on the spot. We did everything right and we got screwed over. Make sure they don't give you any flak about the BIOS flash not being recommended. This is a $300+ "enthusiast" board that is marketed towards people who flash BIOSes. They can't hide behind the statement that BIOS flashing isn't recommended and that we are taking a risk. I'll gladly accept the risk and the consequences if I flash the wrong BIOS or something, but when they release a bad BIOS... they need to stand behind their product and go out of their way to make things right.

Good luck.

I UNBRICKED IT!!!

It is for a different motherboard, but the flash device is exactly the same!

I tried this last night without success (till 3am ), but today I tried it again, and managed to get my backup BIOS to flash the main BIOS!!!

I had EVERYTHING disconnected (especially disconnect the HD, it tries loading a backup from there and keeps failing when it manages to boot).
Take your BIOS battery out, only keep 1 DIMM of RAM, the GFX card and a keyboard.
Keep trying to short circuit the pins in the picture of the main bios, you may get odd results, but if you don't give up you may just revive your board with F4!!!

Method that worked for me is to short circuit the pins a bit after power on.
I can't take any responsibility if you totally nuke your board, but I'm pretty sure this method is safe (as long as it is done correctly), because at times I would short circuit the pins like no tomorrow (believing there is nothing that can be done to save it). So if mine survived, I'm pretty positive yours will do.



Try to spread the word regarding this, so people don't have to pay for a new mobo!

I wish you all luck in unbricking your motherboards and thanks all for the support!!!

Someone has tested the new bios F5 put out the July 25?
Thank You
