Getting P4 video to work in a Sun 4/110

[Josh Dersch]

I've decided to play with some of my older Sun hardware this weekend, it 
seems :).  I have a 4/110 (Sun's first desktop/side Sparc machine) and 
two P4 video cards -- a CG4 (501-1248) and an MG3 (501-1247).  I can't 
get the 4/110 to see either of them.  Running boot diagnostics shows it 
probing for a card in the P4 slot but not finding anything. 

I've hooked the CG4 up to a monitor and the monitor syncs with it and 
displays a blank screen, so it's getting power and doing something, but 
for some reason the machine won't see it.

Any ideas?

Thanks as always...
Josh
