I followed the really simple instructions to flash ATI 4870 1GB card (Powercolor, that is reference I guess) on groths

this is the result :

Modified ROM and original BIOS are exactly the same size but if I understood well it is regular

is it possible that something on EFI adding went wrong?

Using Zeus 2.8 on Lion 10.7.2 and Mac Pro 2,1

This is how the graphic card is seen at the moment

Didn't do any drivers patch

Thanks for your help in advance

Original BIOS attached
