Got it figured out.... My ASUS board didn't like the USB thumb drive I was using. I switched to another and it worked just fine.

As for flashing the cards well that's another story.... thought I had bricked them both LOL. I did one before noticing that this thread was for a 4870... not a 4870 x2, so needless to say it didn't work. So I got the other card out and was going to put the stock bios's back on the other card which was now put in the second PCIe slot... All went well so I thought. Now I discovered that neither card was working!

Long story short... when I had both cards hooked up, ATIFlash put the second card as 0 and 1... the first card was 2 and 3, so everything was ass backwards and not only the cards but master and slave. So after pulling my hair out and going to Fry's to get a PCI card... then figuring out how everything was ass backwards I now have both cards back to stock up and running fine.

I will attemp it again but not tonight and hope all goes well now that I know a little more about this LOL. Oh... And yes I now have the 4870 x2 master and slave bios's thanks to Frank pointing me in the right direction.
