Mod for GTX 750/750 Ti on Asus IBIBL-LB/Benicia-GL8E

[FiftyOneFifty]

I need a custom ROM so my Asus IBIBL-LB/Benicia-GL8E desktop motherboard so it will recognize modern video cards (nVidia GTX 750/750 Ti in particular). Would a mod just be for one family of cards or would it be up to date for everything? I would be willing to pay a reasonable bounty. The IBIBL-LB/Benicia-GL8E was used as an OEM board on HP's. Asus say they didn't design it, so there isn't much support. The newest ROM I could find is from 2009. http://ftp.hp.com/pub/softlib/software11...p46442.exe The system already runs Windows 7 64 bit, so support for newer OS's isn't an issue.

Thanks
