I have an XFX Rx460, I put it in my core2quad computer, but it didn't work, using onboard video, I can't see it in device manager, is there any way to get a uefi card to work on an old system?

Maybe it is just dead.
Maybe just boot some Linux Live CD.
lspci -nnvvv should tell you more than you ever need.

I tested it on another motherboard, a sandy bridge motherboard, and it works. But on my core2quad no. There is no beep, the computer does not try to boot the hd, pendrive or cdrom when it has it I know it's not compatible with old bios, but I think maybe someone knows of a modification to vbios that adds the code necessary for it to work on older systems.

Some graphic cards had a switch to force them to run into legacy BIOS mode. It should be just a matter of flicking the switch to legacy/BIOS..
Proud owner of a Shuttle HOT-555A 430VX motherboard and two wonderful retro laptops, namely a Compaq Armada 1700 [nonfunctional] and a HP Omnibook XE3-GC [fully working :p]
I only know that Radeon R9 290 serie cards had an option for legacy bios or UEFI bios.
My sapphire R9 290 (oc) vapor-x had a button on the card so you could enable or disable the new UEFI bios option.
In legacy mode it would just work on any other older platform. With UEFI you needed a motherboard with UEFI option.
~ At least it can do black and white~
I guess vbios can be flashed to legacy one if there's such rom variant available (haven't tried this myself, so can't advise).
Check Techpowerup's VGA database for a similar model. Can be risky, but you knew that...
(Yeah flipping a switch would be a much nicer!)
They have that "UEFI supported" field in the db, but it might be a good idea to check the rom type (BIOS vs. UEFI) before flashing.
Something like UEFITool might do the trick?
EDIT: In the past I've used rom-parser to check the ROM contents. YMMV.
