REF: QEMM 15 Jun 1993
Using Notework with QEMM
Notework Version 2.0.0 (and higher) can be loaded into high memory using
the LOADHI tool in QEMM under DOS 5.0 (and higher). (In fact, the loading
script NWX.BAT tries to do this automatically. For details, see the topic
"Loading Notework into High Memory".) When loading this way, the machine's
CONFIG.SYS must have either
DOS=UMB
or
DOS=HIGH,UMB
in it.
===== Lockups =====
There have been reports that QEMM's STEALTH feature causes lockup
problems with Notework. Disabling this feature eliminates these errors.
Check the DEVICE=QEMM line in the CONFIG.SYS file. If there is a
parameter ST:M or ST:F in that line, then STEALTH is active.
When using Notework with QEMM, Quarterdeck systems recommends placing the
following in the user's CONFIG.SYS file:
Device=QEMM386.SYS Exclude=A000-C7FF
This prohibits QEMM from using all video memory, which is also used for some
Notework operations.
The Quarterdeck application Manifest routinely recommends placing the
line, STACKS=0,0, in CONFIG.SYS to save memory. This is safe only if
running DesqView exclusively. Both QEMM and the MS-DOS manuals agree
that STACKS=0,0 can cause random lockups (outside of DESQview).
The STACKS default is 0,0 for 8088 machines and 9,128 for 286 machines
and above. If lockups are occurring, try taking the STACKS line out of
CONFIG.SYS until the problem has been resolved.
Upgrades to QEMM version 6.0 may be ordered by calling (310) 314-4413.
The above information applies to QEMM Version 6.0, 6.01 and possibly
later versions.
=====Sticky keys =====
If users have problems with wrong characters coming out, like the <Ctrl>
version of a character coming out although the <Ctrl> key wasn't pressed,
Quarterdeck Technical Support suggests putting the "IA" parameter on the
QEMM386 line. Here is the technical info:
IGNOREA20 (IA) tells QEMM not to trap the 8042 keyboard controller. By
default, QEMM386.SYS traps the 8042 ports for the purpose of detecting
programs which attempt to manipulate the state of the A20 line. Programs do
this to access extended memory. However, sometimes keyboard problems arise
as a result. The IA instruction disables support of HIMEM.SYS, but it may
serve to remove some keyboard-related problems as a trade-off. QEMM-386
supports XMS, and so there is generally no good reason to load HIMEM.SYS.
Other ideas about keyboard problems are discussed under the topic "Keyboard
Problems".
