I assume you are talking about the "384K".

I use mine for a disk cache (PC Tools PC-CACHE).  It increase effective
disk access speed considerably (up to 7 times average with some programs).


You could also use it as a RAM DISK (using DOS's VDISK driver).

MicroSoft Excel comes with a HIMEM driver to automatically use the extra RAM.


And what is the real difference between extended, expanded, LIM, etc. memory:
what programs can and can't use which...

Also, particularly: What type, and how much, RAM can an AT in protected mode
use?

What's the difference between on board memory and bus (or other not on board
memory?) -- (ie: what specification, speed, max size, etc.)
