Remember that memory from 640K to 1 MB on the XT/AT is reserved for I/O.
If your motherboard accomodates 1 MB, it does so as 0-640K and 1MB-1.384MB,
so if you have extended memory (whatever they call it - it's the stuff that's
directly addressed, not paged a la Lotus/Intel), set it to begin at 1 MB plus
384K.
