My high memory maps as follows:

	A000-AFFF	VGA graphics
	BOOO-B7FF	Text display
	B800-BFFF	Free
	C000-C7FF	Video ROM
	C800-CFFF	Free
	D000-DFFF	EMS page frame
	E000-E7FF	Shadow ROM (can't disable)
	E800-EFFF	Free
	F000-FFFF	Shadow ROM (can't disable)

So, it's pretty crowded up there.  EMS means more to me than loading 
PCSHELL in high RAM.
