We have a RasterOps SparcCard in our Sparcstation 1+ (24-bit fb)...At one time
we were able to get X running using the cg8 server on the net...but then we 
installed the update to the RasterOps driver and it busted X..X is there, but
the screen is black...

After many attempts to get info, we were told the following...

-------
Dan, I am assuming you have source for the server. If you do what you need to
do is make an ioctl call (PIPIO_G_FB_INFO) to obtain the memory map offset for
the various frame buffers on the card. This call is described in the file
/usr/include/sun/pipio.h. The values returned are described in that file also.
Rather than using the hardwired offset for the true color buffer (40000
hex, I e
lieve)
use the value returned in the mmap_offset field for the entry whose
group fieldi
s the value PIXPG_24BIT_COLOR (which is defined in
/usr/include/pixrect/pr_plane
groups.h).
-------

Can anyone help me decipher this...where exactly do I put the calls in
the
cg8 server?

All help greatly appreciated.[:)}
