I tried to set "Primary Card" in my BIOS to PCI.
That makes the ATI work, but still only with 8 bpp, no 16 bpp. And then
the Matrox card does not work..=20
If I set both cards to 8 bpp, the ATI works fine, but the Matrox give a
very strange distorted image on the monitor.
Any more ideas? Seems to me that both the cards needs to be "initalized"
to work properly.
And why can't I run the ATI card att 16 bpp?
