After much trial and error I have finally worked out how to add UEFI Gop to a 7950/7970 bios<br><br>
I tested this because my powercolor 7950 has 2 bios, 1 normal and 1 boost but only boost bios had uefi gop, so after some comparing and some failed attempts I have successfully added uefi gop to my non boost bios!!<br><br><br>
So does anyone want to supply me with their bios and I can add uefi gop to it for testing??<br><br>
My idea with this thread is first some initial testing then if all goes well I will write up a how to so everyone can do it for themselves<br><br><br>
So if anyone wants to put their bios on here for me to add uefi gop I will give it a try, please note though to make a back up of your bios before flashing my modded bios and I recommend only those with dual bios to test just in case I will not be the blame for problems and bricked cards so flash at your own risk.<br><br><br>
If posting a bios for me to edit please let me know the exact card that the bios has come from (link to the makers website of it if you can) and also let me know the stock core and memory clock. Without this I cannot help<br><br><br><br><br>
Here are some tested and working bios:<br><br><br>
PowerColor 7950 PCS+ Stock Clocks with UEFI (Mod By Me) 800MHz core:<br>

I have an MSI Radeon 7950 with Twin Frozr III and it is pretty solid as it is, OC of 1200/1575. Will this BIOS increase my overclocking headroom or is it purely to say you can. I haven't really had issues with my BIOS, it is voltage unlocked and everything. Also it is the 7950 PCB (aka boost edition) not the 7970 PCB version. Basically, what can this BIOS mod do for me?<br><br>
Also my motherboard actually has errors (sometimes boots then hangs or just boots and black screens) booting with my card sometimes, I know UEFI GOP can sometime solve this on motherboards with fastboot and CSM like mine. I'm willing to try anything that will fix this, I do have the dual BIOS switch on my card. Sabertooth 990FX R2.0

Basically UEFI Gop will allow you to use the Ultra Fast Boot option on newer motherboards if running Windows 8<br><br>
This mod will have no ill effects at all to any bios as its only adding extra code to allow UEFI Gop it doesn't modify or remove anything else

Okay, I'm willing to give it a try. What program do you suggest I use to pull the BIOS for you. Let me know, I'll do it as soon as I get home.

AtiWinflash as you will need that to reflash will work, or GPUZ pulled mine without a hitch

I read up on UEFI GOP... Pardon my multi posting.... so essentially you are going to take my BIOS and add on the code for the GOP abilities but my BIOS will be otherwise unchanged? Also do you want the BIOS from the switch in position 1 or 2 or both?

Exactly!<br><br>
Well what is difference between your 2 bios? I guess one is with higher clocks?<br><br>
Send both if you like but make sure I know which is which and what the stock clocks are for each<br><br>
Thanks!

I would like to test more before making a full write up but basically you add uefi to the end of the bios and then change a string in the header to let the bios know the uefi code is there<br><br>
EDIT: If you supply me a bios I can edit it for you to test then if it works you can hex compare to see the changes...

So you can confirm UEFI Gop is 100% working with ultra fast boot?<br><br>
Also please list your exact card and its stock clocks so I can add the bios to first post
