Getting Sun Sparcstation 10 to recognize its graphics card

Freeze as in "screen stays blank (but pressing caps lock changes the LED)",
or "system does not boot at all", or "system boots but locks up when
initializing graphics"?

I assume it's just the screen staying blank. Note that using an SGI monitor
on a sun using a 13W3 to 13W3 cable will not work. There's 2 ways around
it: you can either use a 13W3 to BNC cable connected to a BNC to 13W3 cable
to connect the monitor, thus disconnecting all non-RGB pins, or you can cut
off the extra (non-RGB) pins on either side of the cable (I've successfully
done that to connect SGI machines to SUN monitors but it should work the
other way around too).
