I recently upgraded from my speed demon XT compatible to a '286 and it came with 1meg of ram already configured so that 360k was in "expanded memory". I know that "extended" memory is a good thing and many programs are written to take advantage of this extra memory, but what programs use expanded? I can't put any TSR's up there, right? So, I'm essencially doomed to making it a ram-disk (which is nice for all those swap files and such) If I had another operating system (like say unix), could it use this extra 360k? Anybody got any suggestions on other uses for expanded memory?

Oops, a little mistake there. exPANDed memory is the most commonly used extra memory, and can be found on an XT. exTENDed memory is what your AT probably came configured to use it as. If you have the C&T neat chipset, you can change the CMOS setup to configure it as exPanded with the proper driver, but otherwise, the only programs which really use it are Ram disks, disk caches, and protected mode programs.

with extended memory, the first 64k can be used for that, but it requires programs which can use it (QRAM, QEMM, HIDOS, 4DOS, QEXT(dv) ).

You mean extended. You might look at the pc-tools EMS simulator which emulates EMS (exPanded memory) in your extended memory. If indeed you do mean it is set as expanded, look around, tons of programs use it.

hope it helped.
