I think I remember reading that the XGA card uses a 32 bit microchannel
slot.  I don't think that IBM's 286's have any 32 bit slots.

When the clones start coming out, they will probably use 16 bit AT slots,
I would think.  (Someone else mentioned the software drivers for XGA using
386 code - so maybe XGA still won't work on a 286.  But maybe new drivers
can be created.)
