QEMM and Windows 95
Quarterdeck Technical Note #141 Filename: OPTWIN95.QKN
by Michael Bolton & Mike Bryant II CompuServe: OPTWIN95.QKN
Last revised: 8/3/95 Category: SW3
Subject: A discussion on running QEMM under Microsoft Windows 95.
QEMM refers to the following versions of QEMM:
----------------------------------------------
QEMM 7.01 - 7.04
QEMM 7.5 9/17/94, 10/12/95, 11/22/94, 5/12/95
QEMM GameRunner Edition
Overview
----------
Microsoft Windows 95 is fully compatible with QEMM386.SYS, the
driver that supplies QEMM's memory management features,
including QEMM's Stealth ROM technology. QEMM will continue to
provide memory management services to Windows 95 and to the
programs loaded before it.
The Windows 95 installation process will automatically detect
and disable QEMM's DOS-Up features. DOS 7, the version of DOS
that lies beneath Windows 95, is incompatible with current
versions of DOS-Up. The new version of DriveSpace that comes
with Windows 95 is similarly incompatible with QEMM 7.5's Stealth
D*Space and QEMM 7.0's Stealth DoubleSpace, and the Windows 95
installation process will disable these drivers as well. Future
versions of QEMM are expected to address these incompatibilities.
Installing Windows 95 on a QEMM System
-----------------------------------------
At boot time, Windows 95 loads a number of device drivers that
may not have been present in your DOS and Windows 3.1
configuration. These drivers may load into regions of High RAM
in such a way as to alter the region layouts calculated by
OPTIMIZE. After you install Windows 95, to make sure that you
are getting the maximum possible conventional memory, perform
the following steps:
1) Restart your computer in MS-DOS mode by clicking Start,
Shutdown, and "Restart your computer in MS-DOS mode".
2) Using a text editor, edit CONFIG.SYS and add the following
line to the end of the file:
DOS=NOUMB
3) Using a text editor, edit AUTOEXEC.BAT and add the following
line to the end of the file:
CALL DOSSTART.BAT
4) Save the CONFIG.SYS file.
5) Change to the QEMM directory.
6) Run QSETUP.
7) Select Enable/Disable DOS-Up, and disable QEMM's DOS-Up
features. If you are using DriveSpace, select Enable/Disable
Stealth D*Space and disable this feature as well.
8) Select Save Configuration and exit, then run OPTIMIZE.
Installing QEMM on a Windows 95 System
-----------------------------------------
QEMM will install on a Windows 95 System with a little
modification. The following steps will make this sure
that you are obtaining the maximum amount of conventional
memory:
1) Before installing QEMM, you will need to add the following
line to your AUTOEXEC.BAT file:
CALL DOSSTART.BAT
2) Next, add the following line to your CONFIG.SYS file:
DOS=NOUMB
3) Install QEMM, and select Custom Installation.
4) At the end of the installation, you will be presented
with the QEMM Setup scren. Select DOS-Up, and disable
the DOS-Up features. If you are using DriveSpace,
select Stealth D*Space and disable this feature as well.
5) Save the configuration and exit, then run OPTIMIZE.
