Is there any way to restore it back to normal. I've saved PC bios before flash.

If I put an additional HD5770 in first slot, and this HD4870 into second will I be able to boot DOS ? I will take power for HD5770 from molex to PCI-Express power converter and HD4870 directly from board.

The current state is that it chimes and chimes trying to start the EFI on the card.
 
I was able to recover original BIOS and card is working back ok 😉

Can somebody send me a working EFI rom for this card ?
