[comp.sys.ibm.pc.misc] Use of extended memory in AT?

Hi,
	I have a question regarding computer memory.  I haven't been 
reading this newsgroup for long, so please excuse me if it has been 
answered before.
	I have an AT that I bought from someone else.  It has 512K
of regular memory, plus another 512K of extended memory on a separate
card.  This extended memory doesn't seem to get utilized at all.
When I try to run applications that require more than 512 K of memory,
I get an error.  Is there any way I can put this extended memory to
good use and run applications that need 640 K, or do I need to put
another 128k card in there?
