Ahh..  But ISC is with the exception of a few (being phased out) system
calls, completely campatible with XENIX.  Meaning that however XX xenix
program wants to engage your mga, ega or vga graphics card, it can.  See
ISC has all the ioctl calls for both systems in the kernel and include
files (how I know!).  Bottom line, if the software in question has
support for vanilla xenix, ISC can handle it.  That is what there manuals
say.  I personally saw the xenix vga ioctl calls in display.h I believe.
