    I'm trying to write my own EFI to support the 2GB GTX 285 cards.

    I'm trying to extract and decompress the EFI section of the GTX 285 1GB Mac ROM with no success so far.

    I have the tool EfiDecompress.macosx from which gives a decompress error.

    If someone could give any pointers they would be most appreciated.

    I have my "GTX 285 for Mac 1GB" in my Mac right now, and I have the Zeus app, but have never used it and have no idea how to get the ROM out of my card. If you tell me how to do that, I can give that to you. Not sure if that would help?

    No worries, he wasn't the one that 'cracked the code' so to speak.

    Head over to Netkas' forum and you should be helped along.

    Thanks wonderspark I have the GTX 285 1GB Mac ROM though and it doesn't work on the GTX 285 2GB :-(

    I'm trying to decode it to alter it for the 2GB version.

    Netkas forum is great but no help so far!!
