Hi mates, i'm trying to flash the 128kb EFI on a point of view 8800GT for my mac pro 2008 (64bits) but the nvflash told me that the ROM image too large for eeprom. The eeprom is Atmel AT25F512 Anything i can do? Thanks --- Post Merged, Nov 10, 2016 --- searching on internet i find this: Atmel AT25F512 512Kx1S 2.7-3.6V, 128B page, 32k blk, ID=(1F,0065) i need to put the 64bits efi rom for the mac pro 2008 and i don't know if the atmel is 512, 128 or 32 and what amount i need. The .rom file is about 128kb I also have a GTX570 as a second card. If you think in a better card as a first card, i mean to have boot screen, tell me which one are you thinking at.
