I just got the Powercolor HD 4890 1GB GDDR5 Installed Natit Shutdown Remove old 1900xt, installed new Powercolor in slot Booted, Blank screen, hard drive seemed to work, and load the OS, then nothing happened. I shutdown from the button, put the monitor in the different DVI slot, hard drive booted the OS (still blank screen), then went in a loop of rebooting every ~30 sec (could hear chime). What should i do ? I tried to flash using the DOS atiflash on the pc. and i got SSID Mismatched OLD SSID: 2282 New SSID: 8030 I put the card in my PC, and it works fine, but on my Mac Pro 1.1, still no luck.
