Mac: use a Windows ATi Radeon 4870 in your Mac Pro

The price for Windows 4870 cards is substantially lower than Apple’s.
The Canada Apple Store currently
lists one for $420,
whereas
Canada Computers has one for $210.
In
this MacRumors forum thread
people are discussing how to do this and what the pitfalls are.

Basically, download and flash the ROM from
RapidShare.

One person said:

I just tried it on my Sapphire HD4870 (the 1st gen one, based on
ATI’s ref design).

I flashed using freedos and the following command line:
atiflash.exe -p -fs -fp 0 4870.rom
note: -fs and -fp are used to ignore SSID and P/N mismatches

And it works!

EFI driver is initialized correctly, (I don’t have the leaked MacOSX
drivers for this card, so I can’t tell if this one works too), and
bootcamp stil works (currently writing from GNU/Linux on my 2006 Mac
Pro).

Only problem is : only one output is active, no dual-head, it seems
(at least using ATI’s linux driver)

I should note that doing this seems to make the analog output (SVGA) not work. DVI is fine, though one person reported the “top” port as only going up to 1024×768.

Be careful out there. Read the thread for info on which cards work, and what possible side effects there are.

YMMV.
