hi guys,
I have tried to use zeus to add efi to my original firmware but I got an error.
A fellow from macrumors added efi to my original firmware  but when I flashed it , nothing appeared on both display ports, either in windows or osx.
I reflashed it with the original firmware and I am back where I started from.
I have a sapphire 4870 1GB
sku: 21133-04

Also I have downloaded & flashed this efi modified rom:
which has exactly the same p/n and slightly different sku but still no joy!

Any ideas on what can i do next?
Am I stuck with an incompatible card?
