Flash Apple 64bit 8800GT (MB137/ZA) for Macpro 1,1?

[macselecta]

Hi, we recently ordered by mistake the apple 64bit card MB137/ZA,

to go in to a macro 1,1…stoopid I know (the correct version should have been MB560Z/A).

Before I send it back for refund I was wondering if it's possible to flash this card with the 32bit firmware and make it work like a MB560Z/A ?

Before I'm flamed, I have searched and searched for about 2 days but can not find a definitive answer.

So any help from you guys would much appreciated.

Yes.
Search the forum for proper ROM and do it.
