Over VGA or DVI?

Yes, it appears a lot of people have trouble with pulling the EDID on this model; fortunately, it's a very common model and there are Linux Modelines floating about.

I cannot install it. The setup says "The computer does not meet the minimum requirements for installing the software".

My controller is 82845G, and the setup file is for 82945.

Any other way round?

Ah, I hadn't noticed. You're on an 845 chipset, I mistakenly thought 945. I don't think this method will work with 845-- those chipset resolutions were limited to what was in the BIOS. You might be able to hack the BIOS and get it to work, but that's beyond the scope of what I can offer here.

Anyway, thanks for the help so far.

Looks like I have to buy a new controller.
