I am currently using it on a PII 350 - 64 MB with NT 4.0 SP4. It is
good. Did I mention that this server currently works only in full-screen
mode? DX in fullscreen mode does not use Win16 lock on 95/98. So the OS does
not come to a halt.

If I get some time tomorrow, I will post the patches against X-consortium X
sources. May be we can take it up from there?

Mike, there is an excellent document (unfortunately not updated for X11R6)
called "Strategies for Porting X v11 Sample Server". It is in unsupported/doc
directory somewhere in ftp.x.org.

DX supports functionality for fast blitting. Once the server is stable, we need
to take DX routines and put them in ScreenRec in the server. So, selectively we
override the functionality - moving slow functions to directly use DX calls.
