The DOS command is MEM. Try MEM /? to get help for it. Do it in a DOS
command window on modern Windows OS's.

I just tried it (Windows 7-32, ~3G memory), and got

C:\mem


655360 bytes total conventional memory
655360 bytes available to MS-DOS
598480 largest executable program size

1048576 bytes total contiguous extended memory
0 bytes available contiguous extended memory
941056 bytes available XMS memory
MS-DOS resident in High Memory Area

, so I don't think it's that useful for what is wanted here. (I tried
the /p /d /c options too, but I think they still just worked on the
bottom 640K or 1M.)
