Title: Sapphire HD 4870. Added EFI firmware is not working
Post by: ukukey on October 04, 2013, 03:46:27 PM
hi guys,
I have tried to use zeus to add efi to my original firmware but I got an error.
A fellow from macrumors (http://forums.macrumors.com/showthread.php?t=661681&highlight=102-b50702-10-at&page=108) 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
p/n:102-b50702-10-at
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?
thanks
