	For memory below 640K it's called BASE memory.
	For memory between 640K-1M is called a kludge - that area is
	reserved for devices and ROM. If there is RAM there it's because
	a memory manager put it there.

	For memory between 1M and 1M+63K is XMS (eXtended Memory Specification)
	this requires a software driver.

	For 1024K on up it's called extended memory. EMS stands for
	Expanded Memory Specification. It's a sophisticated bank-switched
	memory scheme. And it's a BIG KLUDGE to make up for XT's which
	couldn't acces more than 1M of any kind of memory.

 Cheers!
