This is true.. but I think it would work on analog VGA connection to the monitor.. I haven't really tested this.. the card works as advertised though I do keep it in the SLOT 2 PCI-E and I have the flashed 8800GT in Slot 1. I don't think it's a huge problem.. still rocks that you save $140.
Yes.. the problem is that the FAT partition is the last one.
You will have to go beyond this guide and boot from the USB stick. That way you can write the rom you are backing up from your ATI card to it...
The best thing for you would be to go and get the HP USB Format Utility (http://files.extreme.../file.php?f=197) and boot your mac with that USB drive. That way you will avoid the boot from the disk and DVD procedure completely. You will need to download a different set of boot files for USB (here: http://files.extreme.../file.php?f=196 )
Once you format the USB and make it bootable, you want to copy the ATIFlash 3.79 files onto it too.
Borrowed an extra HDD that was laying around, and I'm now SET! Have to say, you ROCK dude. Never reflashed a vid card before, and your process is just about as detailed as it could be. I owe you a beer or twelve! Gonna go celebrate now.
