5900XT destroyed by bios flash?

[Winnoc]

Hi, i was doinga bios flash of my 5900xt to 5950ultra, and it worked pretty good. I then decided to go flash it back, and as it was writing the old bios back to saveold.rom the power went out.



I tried to reboot, and the card causes 3 different computers not to post anymore.

Is there a way i can still flash a good bios back in that card?


(tried the autoexec trick but it won't do it)

maybe try replacing the cmos on that card it possible. Or get a new bios chip from somewhere. Avaibalble cheap. 1-2$

One thing I dont understand is that why did you flash the card back when it was working fine as 5950 ultra?

boot with a PCI video card while the AGP card is in your system. This should allow you to do it. You may need to boot first with the PCI card only so you can config the mobo bios to boot from PCI first. Otherwise it might keep trying to boot from AGP when you have both cards in.

Once you boot from PCI, you should be able to flash the AGP card.

With newer video cards you can;t sure plop a new BIOS on them so thats not going to work. You have 2 options. 1 is to just do a a blind flash which you'll have to search around for a good tutorial site for or 2 is what Cheetag said. Boot with a PCI video card in and flash the AGP card like that.

Exactly. Same as the autoexec trick, except you can see what's going on.

If it renders a system unPOSTable as soon as you plug it in, well, you've fux0r3d your card and need to go buy a gF6800.

Yeah, well i didn't try the bios options to go for the pci card first.

Guess that's my last hope.

Got a MSI 6800 128MB ordered allready, and i'll get it tomorrow, so if it works i can do my second gaming pc with that "revived" leadtek5900xt.


And yes, it was running great as a 5950ultra, just had to clock down the memory fsb a bit.

Theres a possibility he fried his card and tried to flash it back to original bios to RMA it.
If this is not the case, I really don't understand why else you would want to flash it "slower" than you had it if it was working perfectly. And you have probably read tons of threads about what we think of folks who do this. So you use the excuse of, "I just wanted to see the performance difference.". When you know what the performance difference is already from going from 5900XT 128 to a pseudo 5950U 128.
I'm not getting this. So that just needed saying.

Other than that, a PCI vid card is your only hope of recovering your 5900XT's bios.
