Help with 7970 flashing bios?

[borley]

Hi i seemed to be haveing problems with my bios on my Gigabyte 7970 stock 1000/1375, i use to be able to run at 1150/1650 stock voltage, the voltage is unlocked as its a rev1.
Well it wouldn't let me flash the same version bios just to see if that helps using Gigabyte own utility.
Anyway i came across the Auttomatic GHZ upgrade bios tried that and it works 1050/1500 but it displays no voltage.
So i thought i would try the original bios from gigabyte again with Atiwinflash but i get that common subsystem id mismatch.
Some people say i can use ATIFLASH but im not sure how to use that could someone explain i did read about it ages ago and forgot, something to do with makeing a bootable USB.
Thanks

You need to put Atiwinflash and the bios you want to flash on a bootable USB. Then you boot into dos using the USB and type 'atiwinflash -f -p 0 [bios name, eg. newbios.rom]'.

Well i seem to have worked it out i flashed my bios with the exact one from the gigabyte site using Atiflash on a usb, at first it wouldnt work that also came up with a mismatch.
so googled and the ods command -f worked instead of -fs as said in the tutorial to force it.
Is it write that you can only flash 1 bios?
because for some unknown reason i had problems with both bios not keeping my clocks so i nee to flash them both realy, also i heard if you move the bios switch while the card is on that copies the bios over?
Thanks

You typed that just as i was typing i dont know why in the turtorial it said -fs and it doesnt have to be a bin or rom my file ends .f2 and worked
This is where i got my bios from the exact same model and revision

mine is the bottom bios, as you can see there are newer ones are they for newer cards like different revisions as i can't see and documents saying what the different bios do,change etc?
Thanks

No, just flipping the switch won't copy the BIOS from postion to the other.

I am pretty sure you can re-flash the write protected BIOS if you unlock it first.

Make sure the switch is in the posistion of the BIOS you want to flash. From your bootdisk type:

atflash -unlockrom 0

Then flash your BIOS as usual. When done:

atiflash -lockrom 0

To relock it.
