Feel free to laugh at me, but please also help me if you can... I purchased a 1GB Sapphire Radeon HD 4870 from Newegg several days ago. SKU 11133-19-1GL, PN 288-1E131-000SA. I'm very new to fiddling with the BIOS, and in my enthusiasm I flashed it with something that I was very confident would work without backing up the BIOS. Of course, it didn't work, and I'm left with a card that doesn't work very well and no backup BIOS with which to restore it. I've been scouring the web to find a BIOS, and have had no luck. I did find one with nominally the same SKU and Part Number, but it seems not to be quite right; I've attached it for reference. If anybody out there has recently purchased one of these cards, and has a BIOS that is *different* from the one attached here, I'd be incredibly grateful if you could post it! Thanks so much!
