DESQview 386
By: Charles Olsen, Houston Area League PC Users
Do you need (or want) to run several programs at once, but you say
"phooey" to GUIs? Or perhaps you think Windows is an acceptable
environment, but it turns your 386 with 2M of RAM into an XT (or
worse)? There is an alternative: DESQview 386. DESQview 386, from
Quarterdeck Office Systems, is actually three programs: DESQview 2.0,
QEMM-386, and Manifest. (They can also be purchased individually.)
QEMM-386
The Quarterdeck Expanded Memory Manager-386 (QEMM-386) is an expanded,
extended, and high (640K - 1024K) memory manager. It transparently
transforms your computer's memory into whatever memory your programs
need. If your system has shadow RAM, QEMM will make it usable. Most
other memory managers require you to specify at boot time how much
memory will be EMS and XMS (requiring you to reboot in order to change
the mix). QEMM allocates EMS and XMS as needed, making it easy for you
to run software in different memory configurations without rebooting
the system. QEMM also uses a ROM detection technology called Stealth,
which can find (depending on your hardware) approximately 20K - 115K
of high memory (memory addresses between 640K and 1024K) which can be
used by TSRs and d vice drivers. QEMM's Optimize feature will
automatically determine what TSRs and drivers can be moved from
conventional to high memory. QEMM can map slow ROM code into RAM, to
speed up BIOS services. And QEMM is compatible with Microsoft Windows
real, standard and enhanced modes. Even if you prefer Windows over
DESQview, QEMM is probably your best choice for a memory manager.
Desqview
Whether you need to be running multiple programs at once (such as
communicating in the background as you run your spreadsheet in the
foreground), or simply need an efficient way to switch between
programs when you're interrupted in the middle of a job, DESQview can
help you. DESQview can swap programs to EMS or disk. If you have a 386
(or 486) and QEMM-386, programs that have been swapped to EMS can
continue to execute. Adding new programs to your DESQview menu in
simple -- DESQview is already familiar with many of the popular
programs. If you need to add a program that DESQview isn't familiar
with, you just need to tell DESQview the name of the executable file
and the startup directory. There are other options that may need to be
set, but DESQview's default value s will usually handle these quite
well.
You can bring up the DESQview menu by tapping the Alt key. If you have
more than one program running, tapping Alt twice will switch through
the programs, bringing each in turn into the foreground. DESQview can
record keystroke macros and assign them to various keys. If you want
to use the macros in future sessions, they can be saved to disk. It
can also dial phone numbers displayed on the screen. Popular opinion
holds that multitasking environments will cause more frequent system
freezes and reboots. My system froze occasionally before I used
DESQview, and it froze occasionally while I was using DESQview -- I
didn't see an increase in problems when I used DESQview. Naturally,
DESQview is at its best with EMS for swapping programs. I found that
1M of EMS (2M total RAM) was usually enough to run two programs
without swapping. The programs ran a little slower, but the
performance was completely acceptable even on my slow (16 MHz) 386.
With only 1M of EMS, I found Windows to be intolerably slow.
Manifest
Manifest is a memory analysis tool, telling you everything you ever
wanted to know about your system memory: how much you have, what kind
(conventional, EMS or XMS), how it is being used, and how fast it is.
It also provides hints on how to optimize your use of memory. Manifest
can be run from the DOS prompt, or from the DESQview menu while other
programs are running. The information can be displayed, or printed to
the printer or to disk. Manifest can give you the following
information about your PC:
-The hardware in your PC
-The contents of your AUTOEXEC.BAT and CONFIG.SYS files
-Detailed information on how your first megabyte of memory is being used
-What kind of expanded memory you have (EMS 3.2, EEMS, or EMS 4.0), how
much you have, and how it is being used. There are benchmark test for
determining how fast your EMS is.
-Extended memory availability and usage
-Information regarding how DOS is using memory (DOS kernel, device
drivers, etc.)
-If you're running QEMM-386, information about how QEMM has configured
your system memory
-If you're running DESQview, a report on the status of all the memory
that DESQview controls
-Hints to optimize the use of your PC's memory
-Information regarding video and disk adapters
-Signal states of serial and parallel adapters
-CMOS information
Some of the information provided by Manifest is highly technical, and
not needed by most users. But it can be valuable in troubleshooting.
And the optimization hints are provided in simple English that anyone
should be able to understand and use.
Conclusion
If you're looking for fast, efficient multitasking or task switching,
DESQview can provide it. If you're not interested in multitasking but
you need a good extended memory manager, or need some help in tracking
down weird problems in your PC, QEMM and Manifest are probably what
you are looking for. I wouldn't hesitate to recommend these programs.
