Mod to add UEFI support to old card

[TahoeFred]

Hi, I am messing around with an old system that has 3 EVGA GT640 2048 cards.

I want to try and add UEFI support to them. There is no official proper vbios for this.

This is the card but it has vbios 80.07.55.00.44 in it which shows this card which looks to be pretty much teh same card. but neither have UEFI

I am trying to figure out either how to modify the current vbios file or try one for another similar card.

I do not care if i brick the cards or not.

Any suggestions on finding the most promising candidate ? Here are some potential other cards files to try This Gigabyte has UEFI

What is the most important thing to look at ?

again, this is just for fun and no big deal if i ruin a card.

thanks
