- Interesting, I am running with the service pack. Here is what I get from mem
- in a DOS window with CGA mode restriction:
- ---------------------
- mem
-
-
- 753664 bytes total memory
- 753664 bytes available for DOS
- 722480 largest executable program size
-
- 2490368 bytes total EMS memory
- 2097152 bytes free EMS memory
-
- 2031616 bytes total XMS memory
- 2031616 bytes available XMS memory
- 0 bytes available contiguous extended memory
- DOS resident in High Memory Area
- High Memory Area in use
-
- ---------------------------------------------
- This is my default DOS window that I use ALL the time.
