If it’s the genuine Mac version (with the DVI port) the Mac firmware update utility should happily “update” it back to the Mac ROM. You’ll just need a second video card (or onboard) to interact with the utility.I was wondering about trying to flash the 5500 back, but remember the flash tool would only dump but not reflash the Mac ROM at the time.
