I’ve been using my hackintosh for a good bit now and its fully updated. I recently got a Dell X1300 pro 256 MB (RV516) PCI-e graphics card. It seems this is some hybrid card which is branded as an X1550 else where and has a different ID on each output.  This means the card can not CI or QE, which is kinda important in OSX land, eg: VLC has serious problems playing video via openGL. To add insult to injury this card can’t display BIOS or boot info on Apple Cinema Displays, it seems it doesn’t do Digital DVI from boot, but I could be wrong. 

Okay, to get this card to display boot/BIOS screen, this is what I done:

I went down the HEX editing route mixing V BIOS’s but I bricked the card a couple of times. Used the ATI BIOS by-pass trick to get it back and flashed it form a 4 MB PCI card. Long story short, used Rabit to edit an MSI X1300 (RV515) BIOS bin file to have the same SSID and Device ID as my X1300 pro and then flashed this to the card. This gave me boot up and BIOS display. When the OS driver takes over it treats it as the proper card, don’t know if this has implications for voltage changing, but sure who needs it on a passively cooled card anyway.

To get it to work in OSX (sort of):

Get the latest Natit.kext and edit the Info.plist, change Alopias to Caretta and you get  resolution changing and working display but still no CI/QE.

I’m chatting to a few people on Insanelymac so I’ll be back with an update soon.
