I have a Mac Pro 1.1. My nvidia 7300GT had broken down. I bought a nvidia Geforce 210. Its working fine, but no boot screen at the start, the monitor works once the desktop is opened. Now I want to re-install the operating system. I tried a lot of things, differents cables, HDMI, VGA, DVI, different monitors, different combinations of keys, safe Mode, etc, but the screen remains black in the beggining, so I can not select the way I want to install it, I can not select DVD or USB, the screen remains black, so I can not do anything. Is there a way to re-install the system with black screen on monitor, with a non-EFI graphic card???? Thank you very much.
