    I have both a Promise Technology Ultra100 IDE Controller card (not the TX2 model) and a PNY 2 CH. SATA PCI controller card. the chip number of the Promise card is PDC20267 is there a firmware/BIOS for Mac to make this card bootable? I installed it in the mac and it didnt boot as is and said drivers not loaded as is.

    The PNY SATA card uses the Sil3512 chip i have found a utility to flash the card to a bootable firmware for Mac however when i attempt to flash is it says Unsupported ROM. Does this mean i need to first upgrade the BIOS through Windows THEN flash it in Mac?
