I got in the Sapphire New Edition card today. It has Hynix Memory.
Mac Pro is 2006 1,1
Sapphire Radeon HD 4890
PN: 288-1E115-D20SA
SKU: 11150-11-20R
I turned on screen sharing and took out the 8800GT and put in the 4890. Power is through the 2 6-pin cables to the mother board. Connected from MBP and flashed using the Hynix rom. Rebooted and monitor stays in power save. Connected remotely again and tried booting into Windows 7. Was able to boot into Windows and works great.
Realized that I did not install the qe_ci patch, so rebooted back into OS X and remoted back into it. Installed qe_ci and rebooted and now computer does not boot

Never seems to boot into OS X.
What are my options now?
