I have two ATi Radeon X800, PCI-e variant
Neither of them will output video signal via the DVI port (“no signal”) until Windows starts. So with a single DVI cable connected, the experience is:
1. Turn on PC
2. “No signal”
3. (after 15-20 seconds) Windows desktop appears
The VGA port works fine. I am able to access the BIOS, use DOS, play DOS games etc
So the DVI port will only work under Windows with Windows drivers loaded
Is this expected behaviour for these models? Is this something I can change with e.g. a custom firmware/BIOS? I’d like to use DVI in DOS modes if possible 😎
