I know there are plenty of BIOS files out there, but for some flashing/modding you not only need a BIOS ROM, but also a GOP UEFI ROM file to fully utilize Windows 8.1 Fast-Boot and UEFI mode. I have not been able to find ANY .EFI or .EFIROM files for any of nVidia videocards 6xx series and newer. I know ASUS offers UEFI tool for GTX 680 cards, but not for GTX 770+ because those usually come with GOP UEFI by default. My GFX 770 does not have GOP UEFI by default and it needs one.

Is there a database of UEFI ROMs for GTX 600 or 700 series cards? Is there a way to SAVE current UEFI? I know how to save current BIOS with GPU-Z, but not .EFI or .EFIROM / GOP of my current or any other videocard...

The vBIOS's are hybrid so you can boot via both methods. EVGA started providing them for the 600 series and 700 series comes as-is. Little surprised your current 700 series isn't hybrid by default to be honest.

Saving method via GPU-Z and naming standard (.rom as an example) hasn't changed.

This is ASUS GTX 680 that was first flashed to GTX 680 UEFI using ASUS UEFI vBIOS Tool, which did work and the card did use full UEFI mode. Then I wanted to get Boost 2.0 and flashed ASUS GTX 680 to ASUS GTX 770. It worked and my GPU clocks no longer go up and down much because of Boost 2.0 and its temperature-based OC. It also OC better than GTX 680 1.21v mod. I am going to keep it, but I wish it would work in regular UEFI mode... ASUS UEFI vBIOS Tool detects the card as GTX 680 WITH UEFI, so it should be booting UEFI GOP driver, but it isn't.... I think it wasn't booting UEFI GOP driver because I flashed GTX 680 BIOS to GTX 770 BIOS, but I needed to additionally flash GTX 680 UEFI GOP to GTX 770 UEFI GOP... I need .EFI or .EFIROM files for GTX 770 to complete the flash, but there are none to be found!!! I was wondering if GPU-Z or some other program can separately the UEFI GOP firmware or something to get my card to fully work in UEFI mode...

Another thing is that GTX 680 flashed to GTX 770 is still reported as GTX 680, even though I used nvflash.exe -4 -5 -6 commands, hoping Device ID would change. I guess Device ID is deeply engraved and cannot be changed with a BIOS from a different card with a different/desire-able Device ID???
