    Hello everyone

    I've got this card:


    which I've just put in my 3,1 Mac Pro. I'm happy with it and can survive without boot screens if I have to, but I'd love to be able to flash it so that I get them.

    Is it possible? If it's possible, could someone point me in the right direction?

    I also have a GTX570. Mine is a Gigabyte 3 fan WindForce 3 model. IIRC, the rom on that card is too small to accept the Mac EFI. However, MacVidCards, a site vendor, does modify and can then flash that card for a nominal fee. When I bought my card, I contacted him and forwarded my card to him for the modification. That was back in September. Contact him, I'm sure he'll be glad to help you out.

    Contact him here:

    Thanks Flowrider for the info.

    I'm in the UK, so I doubt the cost of shipping it to the US and back is worth the effort. I can make do with Quickboot, I would just prefer to have EFI boot screens if it's possible. If it's not though, no problem.

    You need new EEPROM, no way around it.

    Old Groth has no idea, because he has never actually done any of the work

    When I see entries in the DB like so:

    It makes me way too scared to ever flash my card with anything from there. Obviously it is not being managed.
