Mac Pro 1,1 (Lion)

[WhiteIphone5]

Ths Mac Pro has a flashed 5870, I know that the old Mac Pro supports lion, but if the card is flashed. How do I go about updating it? There's no boot option right? Since its flashed...

If the card was flashed try running a dvi to vga.....I'm not 100% sure on the 5870 but i know on the flashed 5770 the bootscreen works via vga
