I am designing a computer system which will have memory shared with an
IBM 80286 clone.  We have decided to map the shared memory into an area
above the DOS access space.  I would like to know if any compilers 
provide a "painless" way of accessing this memory without resorting to
assembly language or DOS function calls.

Or is there a way to map 64KB onto the lower (DOS accessible) memory without
interfering with anything else? (Other than upper address latching.)

Any responses will be greatly appreciated.
