I have just recently inherited an IBM AT that has an IBM 512KB/2MB
Memory Option.  This appears to add 2Mb of extended memory to the
system but it still only has 512Kb available to DOS.  I need to run a
program that needs as much DOS memory as it can get, so how do I get
it up to 640K.  Do you need a separate board just for that extra 128Kb
or is there some way to configure some of the 2Mb memory to do that?
