EGA colormap changing under Xenix 386

Over the past months I have been working on a fast graphics device driver
for Xenix 2.2.2 on my 386 box.  (I think the CGI stuff is WAAY too slow!!!)
All is well except that I cannot seem to
change the colormap of the EGA card reliably.  I have looked in many EGA
books and have looked at many code samples in both assembler and C, but
none work when I put them in the device driver!  I can change the map
from within VP/ix without any problem.

If any of you know how to accomplish this task, please let me know!
Pointers are welcome as well.

As soon as I figure out how to change the map, finish my serial
mouse driver, and if there is enough interrest from the net, I will post
the graphics device driver.
