- 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
