If 2 instances are found, go to step 4.ģa. Open myrom it in text edit and search 'mcuc'. Then check if the ROM could hold the EFI. To save your BIOS on the DOS volume, typeīlocknum=`printf %d ''\`dd if=myrom.rom bs=1 skip=2 count=1 2>/dev/null\`'`ĭd if= of=myrom.rom bs=$size seek=1 conv=notruncĢb. Just navigate to your ATIFlash folder (no time to explain DOS commands here).
No need to install DOS (enter 1 at the first prompt, then 2 at the 2nd prompt). Shut down and insert your PC card, remove all other radeon cards (for safety). Download the iso ( fdbasecd.iso) and burn the image with disk utility.ġc. Create a DOS volume with disk utility (it can be added to an existing partition), put the latest version of ATIflash () in the volume.ġb. Work in progress (by Netkas), so be warned.īefore you start, It's always safer to enable file and screen sharing on you Mac Pro (system prefs/sharing).
Notice: the 6870/6850 ROMs are designed for 64-bit EFI Mac Pros (e.g. It's better to make your own ROM, that is, your card's original BIOS + Apple's EFI (ideally, EBC for compatibility with old Mac Pros). This can cause wonky fan behavior or worse. Too many people here flash their PC cards with BIOS that were originally designed for other models. There's not point to flash a card on a hack. EDIT: updated 5770 EFI - should work now.
