QEMM Version 7.0 - READ.ME File
Congratulations! You have just installed the most powerful,
feature-packed memory manager available for 386, 486, and Pentium-
based PC's. Please take a moment to review this text file which
includes a few tips to help you get the most out of QEMM as well
as some last-minute information that did not make it into the
manual. You may want to print this file for future reference.
To do this, be sure you are in the QEMM directory and type
"COPY READ.ME PRN:" at the DOS prompt.
QEMM SETUP - Check it Out!
If you have used earlier versions of QEMM, you may be used
to manually editing your CONFIG.SYS file to add or remove
QEMM parameters--and paging through the manual for help in
determining which ones you need and why. Those days are gone.
QEMM has a new feature called QEMM Setup that lets you quickly
and easily make changes to QEMM. QEMM Setup also contains
valuable information about getting the best use of QEMM, using
QEMM with different hardware, software and versions of DOS, and
troubleshooting information.
To run QEMM Setup, just type QSETUP at the DOS prompt. QEMM Setup
does all this and more:
1) Enables or disables the features you choose, adding the
appropriate lines to your CONFIG.SYS file.
2) Adds or removes some of the more commonly-used QEMM
parameters and explains what they do and when to use them.
3) Provides extensive online help, including detailed
explanations of many features and parameters.
4) Allows you to manually edit your CONFIG.SYS or AUTOEXEC.BAT
file, without leaving QEMM Setup.
5) Lets you view hints and tips, this READ.ME file, and a
collection of troubleshooting and informational technotes.
6) Tells you if you need to run QEMM's Optimize program after
changing your configuration--and then runs it for you.
With the addition of QEMM Setup, you not only have the most
powerful memory manager, but the easiest one to use.
GENERAL INFORMATION
STEALTH ROM and STEALTH DOUBLESPACE - Use of EMS Page Frame:
QEMM's Stealth ROM and Stealth DoubleSpace (ST-DBL) features
depend on the existence of an EMS page frame. QEMM installation
normally sets up a page frame in upper memory. If you want to
use the Stealth features, you must do nothing that would
eliminate the page frame (i.e., do not use the parameters EMS:N;
FRAMELENGTH=0, 1, 2 or 3; or FRAME=NONE on the QEMM386.SYS
device driver line in CONFIG.SYS.)
TROUBLESHOOTING QEMM
You will find general troubleshooting information in Appendix A
of the QEMM manual. There are also several technical bulletins
included in the \QEMM\TECHNOTE directory on your hard drive.
These "technotes" cover a variety of issues such as Exception 13
messages and using QEMM with Microsoft Windows, Stacker and
other programs. For information on the technotes, see Appendix B
of the QEMM manual. You can view the technotes from the QSETUP
program or from within your favorite text editor or viewer.
COMPATIBILITY ISSUES
QEMM is compatible with almost all popular hardware and software.
Although compatibility problems are rare, we have compiled a list
of hardware and software products that require parameters,
excludes, etc. when used in conjunction with QEMM or Stealth ROM.
If you have problems with a specific program or with your system
after installing QEMM, you should refer to the technical bulletin
PRODUCTS.TEC for information on resolving compatibility issues.
This technote can be found in your QEMM\TECHNOTE directory. You
can view it from the QSETUP program or from within your favorite
text editor or viewer.
DISK COMPRESSION SOFTWARE AND OPTIMIZE
QEMM now has automatic support for Stacker versions 2.0 - 3.1
and SuperStor 2.0, 2.04 and SuperStor Pro. If you use either
of these disk compressors, see the appropriate technote file
(STACKER3.TEC or SSTOR.TEC). These files are located in the
QEMM\TECHNOTE directory. You can view them from QSETUP program
or from within your favorite text editor or viewer.
If you are using XtraDrive, refer to XTRADRV.TEC.
If you are using DoubleDisk Gold, read DBLDISK.TEC.
Space MANAger by Vertisoft is not compatible with QEMM's new
Stealth DoubleSpace feature. DO NOT use Stealth DoubleSpace
(ST-DBL) if you are using this program. Doing so can result
in loss of data on your hard drive.
OPERATING SYSTEMS
MS-DOS 6:
MS-DOS 6 gives you the ability to create multiple CONFIG.SYS and
AUTOEXEC.BAT blocks and choose from the various configurations
at boot up. QEMM 7's Optimize supports this feature of DOS 6 by
allowing you to choose which configuration you wish to Optimize.
For more information on running Optimize while using multiple
configurations, see the text file MSDOS6.TEC in the QEMM\TECHNOTE
directory. You can view it from the QSETUP program or from
within your favorite text editor or viewer.
DR DOS 6:
For information on optimally configuring DR DOS 6 with QEMM 7 and
DOS-Up, see the file DRDOS6.TEC in the QEMM\TECHNOTE directory.
You can view it from the QSETUP program or from within your
favorite text editor or viewer.
NEW PARAMETERS
XBDA:x (QEMM386.SYS parameter)
By default, QEMM detects the Extended BIOS Data Area (XBDA) on
systems that have it, and moves it away from the top of
conventional memory to a place in High RAM. However, if QEMM
detects that you have a Suspend/Resume feature, or if you place
the SUSPENDRESUME parameter on the QEMM386.SYS line in CONFIG.SYS,
it will by default move the XBDA into conventional memory.
(This is done in order to retain the use of the Suspend/Resume
features.) QEMM will also place the XBDA in conventional memory
if there is no available High RAM. When the XBDA is in High RAM
or conventional memory, QEMM is still able to perform video
filling on monochrome, Hercules and CGA systems. Moving the XBDA
does not prevent the use of VIDRAM on EGA/VGA systems, nor does
it reduce the size of DESQview or DESQview/X windows by 16K.
The XBDA:H parameter forces QEMM to put the XBDA in High RAM
(if there is any available) even if you have a Suspend/Resume
feature. This parameter can save you 1K of conventional memory,
but you risk Suspend/Resume not working properly.
The XBDA:N parameter tells QEMM not to move the XBDA. XBDA:N is
a common troubleshooting option, and is needed whenever a ROM or
an application assumes that the XBDA is located at the top of
conventional memory. The symptom of this problem is usually a
system crash, which can occur at boot time or later, or a failure
to access a disk.
The XBDA:L parameter forces QEMM to move the XBDA to low
conventional memory instead of High RAM; this decreases
conventional memory by 1K, but preserves all the other benefits
of moving the XBDA. This parameter is therefore a less drastic
solution to XBDA-related problems than XBDA:N, although XBDA:N
will solve some problems that XBDA:L will not.
LOADHI.COM /ENVHI (or /EH)
(LOADING THE DOS ENVIRONMENT INTO UPPER MEMORY)
There is a new LOADHI.COM parameter, /ENVHI (abbreviated /EH),
that is used to load the command processor and the DOS environment
into upper memory. Because many network shells will fail if the
environment is loaded high, you should only use this parameter
if you are NOT using a network.
QEMM's DOS-Up feature normally loads your command processor into
upper memory by adding LOADHI.COM to your SHELL statement in the
CONFIG.SYS file. With the LOADHI.COM syntax added, your SHELL
statement would look something like this (with the n in R:n
replaced by a High RAM region number):
SHELL=C:\QEMM\LOADHI.COM /R:n C:\DOS\COMMAND.COM C:DOS\ /E:2048 /P
DOS's default environment size is 160 bytes. If you need more
conventional memory (and, especially if you are using the /E:
switch on your SHELL line to create a larger environment) you may
want to add the /ENVHI parameter to have QEMM load the command
processor and the DOS environment into upper memory as follows:
SHELL=C:\QEMM\LOADHI.COM /ENVHI /R:n C:\DOS\COMMAND.COM
C:\DOS\ /P /E:2048
In the above example, the /ENVHI parameter would gain you an
extra 2K of conventional memory by loading the environment into
upper memory. (NOTE: In our example above, all parameters
should be typed on the same line.)
NEW EMS PARAMETER ARGUMENTS
Chapter 11 of the QEMM manual describes the EMS utility programs.
On page 115 is a description of several parameters to EMS. The
CREATE, CREATEFAST, CREATESLOW, and RESIZE parameters each take
an argument nnnnnn[K] that expresses the amount of memory to
allocate. There are some new ways to express this amount of
memory:
You can use the letter M instead of K to express a value in
megabytes.
You can use the argument ALL to specify that all memory
should be allocated.
You can use the argument ALL-nnnnnn, ALL-nnnnnnK or ALL-nnnM to
allocate all memory minus a specified number of pages,
kilobytes or megabytes.
FILES CREATED AND USED BY OPTIMIZE
HINTDATA.OPT - Used by MANIFEST after the OPTIMIZE process for
providing optimization hints.
UNOPT.BAT - Restores CONFIG.SYS and AUTOEXEC.BAT as they existed
before you most recently ran Optimize. Requires the presence of
the AUTOEXEC.QDK and CONFIG.QDK files created by OPTIMIZE.
OPTIMIZE.INF - User-readable file that contains information
about the OPTIMIZE process.
OPTIMIZE.DAT - Data file that holds information used when
processing called .BAT files.
LOADHI.OPT - Output file generated by the LOADHI programs during
the Detection Phase and processed by OPTIMIZE during its
Analysis Phase.
CORRECTIONS TO QEMM MANUAL
P. 20 In the third paragraph in the section "Booting Without
QEMM," the last sentence should read:
If you are using QEMM's DOS-Up feature, you will see a message
asking if you want to unload it; press Esc to unload DOS-Up,
then IMMEDIATELY press and hold down Alt again.
P. 22 Near the bottom of the page, the line that loads QEMM's
DPMI driver should appear as follows (all on a single line):
DEVICE=C:\QEMM\LOADHI.SYS /R:n C:\QEMM\QDPMI.SYS
SWAPFILE=DPMI.SWP SWAPSIZE=1024
P. 24 The fifth paragraph from the bottom of the page, concerning
DR DOS, is incorrect. Please see the text file DRDOS6.TEC in the
QEMM\TECHNOTE directory for information on using QEMM with
DR DOS 6. You can view it from the QSETUP program or from within
your favorite text editor or viewer.
P. 39 The second paragraph should read:
DOS-Up will modify it to read:
SHELL=C:\QEMM\LOADHI.COM /r:x C:\DOS\COMMAND.COM C:\DOS\ /P
P. 56 In the description of the RAM parameter, the first sentence
of the second paragraph should read:
If you specify the RAM parameter without an address range, QEMM
sets aside room for an EMS page frame (unless you are using the
EMS:N, FRAMELENGTH=0, 1, 2, or 3, or FRAME=NONE parameters) and
places High RAM at all other upper memory addresses at which
QEMM has not detected ROM, video RAM and adapter RAM.
P. 89 The LOADHI parameter @[:file] has been renamed to
/RESPONSEFILE[:file] (/RF[:file]). @[:file] is still
accepted by the LOADHI programs.
P. 120 In the first paragraph of Step 6, the parameter TM:N is
incorrectly listed as TM:M.
