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? John Kellow
