WHAT IS QEMM 7.0?
-----------------
QEMM 7.0 is the newest version of Quarterdeck's award-winning memory manager
for your 386, 486, or Pentium-based computer. It will give you more memory
for your DOS or Microsoft Windows programs than any other existing memory
manager.

QEMM 7.0 introduces a number of new features. This document will give you an
overview of the new features and changes since 6.0, and will go into detail on
some of the more important and interesting ones.


WHAT NEW FEATURES DOES QEMM 7.0 HAVE?
-------------------------------------
DOS-UP:
QEMM 7.0 introduces DOS-UP, which will allow you to increase your available
conventional memory, even if you already have everything loaded high. It does
this by moving the portions of DOS that DOS=HIGH doesn't move. More on this
later.

OPTIMIZE improvements:
OPTIMIZE can now account for programs that load themselves high; it is aware
of DOS conditionals (such as IF and FOR); it has improved detection of
Adapter-RAM and other trouble-spots above 640K; and it is now fully aware of
MS-DOS 6's multiple configuration boot setup (something even Microsoft's own
MemMaker can't handle).

VIDRAM improvements:
VIDRAM is now capable of working in a Microsoft Windows Enhanced Mode DOS
Window, as well as from normal DOS. This will allow your DOS text-mode
programs to access an additional 96k of conventional memory, bringing your
maximum available to almost 704K in a DOS partition of MS Windows.

QEMM Setup program:
A new program that comes with QEMM 7 is called QSetup. It allows you to
change the configuration of QEMM, DOS-UP, ST-DBL, QDPMI, and the other QEMM
programs, without having to manually edit a single text file. All of the
available options are available on menus with full help explaining what each
one does. In addition, troubleshooting support is built-in to QSetup, so it
is easier to give QEMM the information it needs to cope with rare or
non-standard hardware.

32-bit performance:
Major portions of QEMM have been rewritten to use 32 bit code; this results in
faster operation, and less conventional memory overhead. (Less than 1K of
your conventional memory is used by QEMM).

Compatibility enhancements:
QEMM 7 also has a number of compatability improvements designed to make more
software work better than ever before. It now supports VESA, and can save and
restore the vectors as necessary. It knows about more types of Shadow RAM,
Compaq Models, and Bus-Mastering disk drive controllers than it did before. It
has special features for the Intel Pentium, that allows it to use less memory
and work faster on those machines.


WHAT IS DOS-UP?
---------------
DOS-UP is a set of utility programs that QEMM and Optimize use to load more of
your DOS kernel (the actual DOS program and its data) into upper memory. This
will give you more conventional memory than ever before, even if you already
have everything on your system loading high.

DOS-UP actually consists of two drivers: DOSDATA.SYS and DOS-UP.SYS. Both are
necessary for DOS-UP to work properly.

DOSDATA.SYS needs to be the very first line in your CONFIG.SYS. Its purpose is
to "prepare" DOS so that it is in the proper place to be loaded into your
upper memory.

DOS-UP.SYS comes after QEMM loads in the CONFIG.SYS. It does the actual work
of moving the pieces of DOS into High RAM, and making sure that other programs
will know about this new location.

DOS-UP can give DOS 5 and 6 users an additional 7 to 20k of conventional
memory, and can give DOS 3 and 4 users an additional 50 to 60k (depending on
their prior configuration). It also allows you to get DOS out of your
conventional memory without DOS=HIGH, which allows DESQview or some other HMA
user to have the full 64k of HMA, instead of only the 35K that DOS=HIGH uses
by default.


What about support for Disk Compression programs?
-------------------------------------------------
QEMM 7.0 has better support for disk compression programs such as DoubleSpace,
Stacker, and Superstor. Both QEMM and Optimize will recognize the disk
compression program and make sure that they are handled correctly. In
addition, there is a special Stealth DoubleSpace feature which saves even
more memory.


What about Manifest?
--------------------
QEMM 7.0 comes with the newest version of our award-winning Manifest: Version
2.0. Manifest lets you take a look "under the hood" of your computer. It's
the best way to find out exactly what's going on inside your machine.

There are quite a few new features and information screens incorporated into
the new Manifest 2.0. It now has built-in editors for your system
configuration files (CONFIG.SYS, AUTOEXEC.BAT, WIN.INI, and SYSTEM.INI),
all available at the touch of a hotkey. It will now show you information on
your Microsoft Windows configuration, as well as your DOS configuration. It
includes information on the version and drivers that Windows is using. It
also provides enhanced network information, showing network type, servers,
drive mapping, and login information. It provides more information on your
video than ever before, including the make and model of your video card, and
the amount of memory installed on it. It provides full information on your
battery condition on those laptops that support the "Advanced Power
Management" specification. Finally, it shows you complete information on
every type of memory available for your computer today, including EMS, XMS,
VCPI, and DPMI memory.


How can I get an upgrade? How much will it cost?
------------------------------------------------
The cost to upgrade from any version of QEMM to version 7.0 is $35, plus $5
shipping and handling. If you purchased a prior release after April 15, 1993,
your upgrade is free (plus $5 shipping); just mail or fax your proof of
purchase.

Our order hotline is (800) 354-3222.

Upgrades to DESQview and DESQview-386 are also available; call us for complete
details.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
