The funniest thing happened to me. Yesterday, when I booted my
dos partition, I noticed I had no UMB's. I was rather surprised,
since I hadn't changed anything since I last used dos.
And behold, the himem.sys and emm386.exe settings were still
ok, yet, from the dos prompt (4dos or command.com) I could not
see any UMB's, emm386 repports 0 bytes available/free UMB
but a correct UMB start segment (C800), SI repports no UMB server
present, BUT the drivers in DEVICEHIGH's were loaded high and
functioning!!!
How's that for a mysterie. Has my processor maybe gone off DOS
after having been running OS/2 for a while now :-) ?
I reinstalled DOS, reformatted c: disected config.sys, and what
else. No indication of failure. OS/2 runs fine, checkit confirms
the system board to be ok, yet, NO UMB's.
My suspicion is rather arroused though, by the fact that SI,
repports different memory sizes in the various info screens.
It finds 638 to be useable by DOS, yet 640 to be available.

If you figure this out before I do, let me know. I am indeed
curious as to what might be causing this.

Cheers
Erik
