Actually, the XGA adapter will only run in full-blown 386 machines using
MicroChannel archetecture.   Except for the 32-bit busmaster capabilities,
the XGA specification is virtually identical to the 8514/a spec.  XGA is
much faster, but what do you expect from a card with a computer on board
combined with a superior bus.

As for the clones being 16-bit.  If its not a 32-bit busmaster, it's 8514/a
and NOT XGA.
