- True. WHat is particularly annoying is the inability to get LOADHIGH to
- tell you what is currently loaded high. You can it from "MEM /P", though.

- Anyway, three other interesting things I've noticed:
- 1) My default CONFIG.SYS contained the line: DOS=LOW,NOUMB
- I changed this to DOS=HIGH,UMB, but it seemed to make no
- difference in my DOS sessions. I guess it must only be
- parsed at OS/2 boot time. (Weird!). Anyway, I haven't tried
- rebooting to test this theory.
- 2) I then turned the DOS_HIGH and DOS_UMB switches in the DOS
- window notebook on, and that seemed to do the trick.
- However, I now get a funny looking MAPMEM, as shown below.
- Any idea why?

- 3) Finally, for some reason, QD refuses to be loaded high. (I
- have to load it low). Needless to say, this has never been a
- problem with QEMM's LOADHI. As I noted in another post, it
- complains that it is already installed and refuses to
- install (when attempted to be loaded high).
