10/18/91 - Beta version 1.00B released to public domain
10/24/91 - Fixed logic flaw in error detection in use of Proc
QueryFreeMemXMS - XMSerrors $A0 and $A1
are result codes, not real errors.
- Fixed minor bug in display where exactly one screenfull
for Conventional and Upper memory. Rearranged
output - placed "NO EMS" and "NO XMS" messages on
last page of display.
- Assigned new minor version number - 1.01B
11/02/91 - Added display of standard extended memory amount
total/used/remaining and XMS extended memory amount
total/used/remaining/largestblock
- Fixed minor problem displaying XMS error returns
- Fixed minor problem checking for link of UMB to Conventional
and DOS = UMB in CONFIG.SYS
- Patched executable to work with more than 640k
- Assigned new minor version number - 1.02B
11/21/91 - Added summary display of location of command shell
- Changed detection of location of DOS=High to location
of current disk buffer where possible; If running
under DOS 5.xx DOS furnished DOS location
- Added support for DR-DOS 6.0 (Signs on as DOS 3.31)
- Changed algorithm to detect whether UMB's are linked
through pointers to Conventional memory (CNV link)
MS-DOS and DR-DOS and QuarterDeck patch top of
memory one segment lower than before installation,
with the resulting MCB having a 'Z' ID byte, and
pointing to MCB controlling UMB's (I think).
- Added support for 4DOS command shell
(May work for Norton Utility's NDOS?)
- Added detection of location of command shell
i.e. Conventional Memory, UMB, HMA, and
display of command shell name, where possible
- Added automatic detection of output redirection, and
force page breaking off if redirected to anything other
than standard output
- Assigned new version number - 1.50
12/17/91 - Added additional support for DR-DOS 6.0 and 4DOS 4.0
- Detects additional DR-DOS UMB owner segments
8 = DOS configuration
7 = Reserved from UMB pool for video, etc.
6 = Used by UMB Device Driver (not DOS)
- Added display of unused XMS handles
- Added display of UMB usage as Reserved-HiLoaded-
System Loaded and Self-Loaded (Program loads itself high)
- Assigned new version number - 2.00
