very stupid idea concerning gigabyte motherboards

[kokodin]

Lately i had been thinking about very stupid thing i would like to try, but i have no idea if that would be even possible , doable most likely , but the end recoult might be just a poof of smoke, and i like the idea of living on the edge.

but to the point
i currently have 2 sandy/ivy bridge motherboards with celerons that are colecting dust
ga-h61m-d2-b3 (\rev 1.0)
they are already hacked for a company that sells computers for schools so the bios isn't even the oryginal one, or at least traces of "actina costa w7p 300g" computer are still present in the bios somewhere, i can dig them out with hwinfo64

the problem with the motherboard is not really a problem, they are quite old and runing old award non uefi bios and i would like to hack ami uefi onto at least one of them for fun
it is most likely crazy idea but gigabyte in it's wisdom released multiple boards with practically identical features and periferials so i was able to find one board that could work as a uefi donor
GA-H61M-DS2V
they apear to have the same mainboard controller, the same audio, lan and usb count (also all 2.0 usb only) the same chipset,same layout of pcie slots, and both have dual 32mbit flash for bios/uefi chips

so i was wondering would a board hacked like that even post? and if yes does uefi have to be strictly hardcoded for any motherboard quirks , or is it a more flexible firmware that could take some gueses about what is what.
would it had to have the same power delivery setup?

i know it could at best be unstable board with unpredictable bios/uefi setup and at worst go up in flames around cpu if it go crazy, but i am wiling to destroy one for experiment like that

if you have any sugestions about how to do it safely or do you know other reasons why it simply couldn't work , i would be very interested in your input and experience
