This won't be a super-detailed step-by-step tutorial on every single aspect, but instead an overview on most important topics with links to further information. I'll explain how to find perfectly compatible cards and how to improve the overall experience on not so compatible GPUs. However, before getting too excited there are a few things to consider to achieve hassle-free long-term compatibility, so I've composed this guide to collect all necessary information and to clarify some urban myths. This would make many people assume that they weren't compatible with OS X at all, but in fact Apple has included driver support for almost every relevant AMD graphics chipset from the last years, so there's a good chance your standard PC card will work out of the box! Most of you might have noticed that the Buyer's Guide doesn't list a single compatible AMD Radeon card at the moment. The "boot to black screen" issue as well as the broken sleep/wake have been fixed! Read below for details. If anyone could help me flash my LE to a retail, and then help me flash the retail to a Mac edition (or direct me to somewhere I could get help) that would be great.Building a CustoMac Hackintosh: Buyer's Guide I have searched the internet for relevant links, but I could only find a few, and they were in languages which I could not read. But if the cards are the same, wouldn't the card be able to handle either BIOS? The reason he said maybe was because the cards were technically the same, but the Mac BIOS was bigger for some reason and he wasn't sure if it would 'fit'. Last year at MWNY (Macworld New York) I asked an ATI rep if a flash of a Radeon 8500 to a Radeon 8500 Mac Edition would be possible and he said maybe. If the card can handle overclocking in Windows to 275/275, flash the BIOS to 275/275 Retail. Flash Radeon 8500LELE to a Retail 8500 BIOS version at 230/230.Ģa. It tells me I have a file access error or something.

Atiflash doesn't seem to like being run on a boot CD, or maybe I am trying to flash incorrectly.

I have never flashed my video card BIOS before, but I have flashed my motherboard BIOS and DVD-ROM BIOS before using a boot CD. My G4/400 Sawtooth, which can take a Radeon 8500 Mac Edition, is still only using a Rage 128 Pro. I recently bought a 9500 non-pro and have no more use for my old Radeon.
