Modifying VBIOS for UEFI support

[revoconner]

I have a gtx 560 ti AMP from zotac and a windows 8 set to boot from UEFI. Since my VBIOS of the graphics card isn't compatible with UEFI boot i have to enable legacy boot too and that results in the same amount of boot time. Is there any way to modify the VBIOS of the graphics to support UEFI boot? Using Nibitor or any other method.

The VBIOS should not care if the BIOS has legacy enabled or not. The only thing that matters is how you installed you OS on the hard drive.

Okay so I'm not sure what's happening here. I have integrated graphics HD 4600 and a GTX 560 ti. Now once I installed Windows 8 as legacy boot but later converted it into UEFI using gdpedit. Now if i disable legacy boot the screen remains blank and to restore it back I have to remove the graphics card from PCIe slot and plug the monitor to motherboard. But if i have both the boot available the graphics card doesn't have any problem. Any idea?
