[SPARCbook] How do I run Solaris Xsun at > 16 bpp

[Michael Wolfson]

Howdy,

I can't seem to get my 3GX (from Ross Pennington) to display at anything
other than 8 or 16 bpp, even though the specs say it can do 24 bpp properly.

Using Xsun from Solaris 2.6 3/98 and fbconfig -m 4, I get garbage on my
screen (flashy yellow stuff primarily).  I tried using two of the
pre-compiled X11R3 Xservers out there, and they didn't even find the
p9100.

Any suggestions?

Thanks,
