Visiontek / HIS Radeon 4870 1GB Flash
Hi all,
I recently picked up a VisionTek B2 4870 1GB card for $130, so I have been reading through the forums preparing my custom rom. I have a 2009 mac pro that is currently being serviced for a broken logic board, so I am playing with flashing my card in DOS on a Dell PC with a PCI-e slot (I wanted to get a jump start before my computer gets back).
I havent been able to find anyone using the exact card that I have, but it is a Visiontek 4870 1GB (looks like a repackaged HIS) the model number is: 900286.
It is hard to find a picture of the card that looks like mine, but this is the one that looks most like it (except mine has a visiontek sticker and is 1GB not 512mb):

I backed up my original rom using atiflash in DOS, and then I created a custom rom using the method described in Cindori's tutorial here (I had to edit and do the MCUC fix). I flashed this rom to the card and it booted back up in the pc, working great in windows. I also tried flashing a Sapphire 1GB rom from the 4870/4890 ROM package included here, and that also booted into windows working fine.
I am wondering, to Cindori or anyone who can provide a little insight...
If I flashed the card with a custom EFI modded PC rom and the provided Sapphire 1GB rom and it works fine in windows, is this a good gauge that this will work in my mac pro when I get it back?
If someone wouldn't mind taking a look, I have attached the two roms that I used which successfully booted back into windows, as well as the original PC rom for my card. I figure there is no way to know for sure until I get my mac back, but I am anxious to know if I am doing this right.
By the way this thread rules! Cindori you are the Man! Thanks to everyone who has helped n00bs like me get this stuff working (or at least try).
