[Nice solution to DMA buffer above 640K using XMS snipped]

Cool.  A nice piece of code to keep as an example.  It does depend on XMS
memory being free, so you must be running under a memory manager.  If you
are running under XMS alone (no emm) with CWSDPMI, it would allocate it all.
Under some other DPMI environments, I don't know what they would do either.
This will also mess up the perceived free memory in CWSDPMI (but this 
normally shouldn't matter).

This is a nice solution to big DMA buffer requirements, thanks!
