    Hi,

    I've a problem with the original ATI 2600XT mac version (in macpro 4.1), my friend have flash it with windows firmware and now my mac don't recognize it.

    I tried to flash it with many firmware found in internet but not works (always black screen).

    Please tell me how I can find right bios (with efi64) and how I fix it for use again in my macpro.

    Thank you.

    All mac efi roms contain pc bios !!!! Don't need a reflash to work in windows !!!!

    Thank your friend for wasting a bunch of your time.

    The very first Mac EFI card from ATI did not include PC BIOS, the X1900XT. Since then, EVERY SINGLE MAC EFI CARD HAS CONTAINED A FULL AND COMPLETE PC BIOS.

    This is why the cards work in bootcamp.

    This is why the roms are frequently too big for the PC card EEPROM chips.

    This is why these cards justify higher cost, they work in multiple machines / multiple OS's OOTB.

    WITH EXCEPTION OF X1900XT ALL APPLE EFI CARDS WORK IN PC'S WITHPOUT ANY MODS OR FLASHING NEEDED

    Once you get this through your friend's head, you might also want to point out the absolute GOLDEN MAXIM of card flashing.

    ALWAYS BACKUP YOUR ORIGINAL ROM BEFORE EXPERIMENTING WITH OTHER ROMS. !!!!!

    [Quote = "MacVidCards, de la publicación: 17278875, miembro de: 592511"] Todo mac ROMs contienen EFI BIOS de la PC !!!! No se necesita un reflash para trabajar en ventanas !!!!



    Gracias a su amigo por desperdiciar un montón de su tiempo.

    La primera tarjeta de Mac EFI de ATI no incluía la BIOS del PC, la X1900XT. Desde entonces, todos y cada MAC TARJETA A EFI BIOS contenía un modo exhaustivo PC.

    Esta es la razón por las tarjetas funcionan en el campo de entrenamiento.

    Por esta razón, los roms son con frecuencia demasiado grande para los chips EEPROM de la tarjeta PC.

    Por esta razón, estas tarjetas justifican un mayor costo, que trabajan en varias máquinas / múltiple OOTB del sistema operativo.

    A excepción de X1900XT TODO APPLE EFI TARJETAS DE TRABAJO EN LA PC WITHPOUT grandes modificaciones o parpadeando NECESARIO

    Una vez que llegue esto a través de la cabeza de su amigo, puede que también desee señalar la máxima de oro absoluta de parpadeo tarjeta.

    Siempre copia de seguridad ROM original antes de experimentar con OTROS ROMS. !!!!! [/CITAR]
