GTX280M in an early 2008 iMac?

05 April 2016 - 05:10 AM

I have a nvidia G92-761-B1 based 1Gig MXM HE card (maybe a GTX280M?) that I'd like to put in my early 2008 24" A1225 (EMC 2211) iMac.  (This is part of an upgrade to sata ssd, OWC's 6gig of ram, and a new 3.06GHz Intel Core 2 DUO Mobile E8435 SLAQD 6MB 1066MHz processor.  Might as well do it all at once)

From my research all the items except the video card should be 'plug & play'.  I expect I'll need to re-flash my video card with an apple rom.  I think I can use the 8800GS rom that was an option for this iMac, but I know there are better choices to be able to utilize more of this video card.  maybe a 9800 GTX+ rom? Can someone point me to an existing rom that would be best for this card or do I need to try and stitch one together?  My rom chip is a SST25VF512A-33-4C-SAE (512k), but I can replace it if needed.

I found a GTX 285 EFI64 rom from http://forum.netkas....pic,2187.0.html(http://dl.dropbox.com/u/4133784/OrigRom/evga285m.rom) which might work?  I'm worried because most of the roms I find are for PCI cards in mac pros.  This is a MXM HE card (PCI ish), so is the rom different?
