Reflash 8800gt 64 bit (MB137z/a) to 32 bit (MB560Z/A)?

[wooliez]

Hi All

I have a MacPro1,1 with the original nVidia 7300. An 8800gt (MB137z/a) was made available to me, but unfortunately does not work because this is the 64-bit EFI version.

Is it possible to reflash this card to 32-bit EFI (same as the MB560Z/A?).

Alternatively, I am open to trading the card itself for the 32 bit version if anyone would like to do this.

Thanks.

I asked around and was able to obtain an MB560Z.

Would this card still be available by any chance?
