Hello, what does OS/2 and non-OS/2 mean in bios setup? I installed more DIMM, I have 256MB now but in non-OS/2 it showed hardly any free memory, So I set it to OS/2 and the free memory went way up. The book says "set to OS/2 if using more than 64MB and running OS/2" It seems to work fine in OS/2, just wondering what it means. Sorry if its a dumb question. TomW
