                   DOS 5 and QUARTERDECK PRODUCTS


  This QEMM 7 technote is an abridged version of a technical
  bulletin that is available through our standard support channels.
  The information contained in this version pertains ONLY to QEMM
  version 7.0.  If you need information relating to earlier versions
  of QEMM or if you are interested in a lengthier discussion of this
  subject, you can obtain the unabridged version from the following
  sources:

  Quarterdeck Technical Support BBS:  DOS5.TEC
                         CompuServe:  DOS5.ZIP
                              Q/FAX:  #200


  Subject: Information on the use of DOS 5.0 with Quarterdeck
           products.


  The shipping versions of all Quarterdeck products are compatible
  with IBM and Microsoft DOS 5.

                        UPGRADING -- THE EASY PATH

  INSTALLING DOS 5 OVER A QEMM SYSTEM:

  If you are installing DOS 5 on a system that already has QEMM
  installed, simply leave the Quarterdeck memory managers in place
  and run the DOS SETUP program.  SETUP will detect that a
  compatible memory manager is installed and will not replace it.
  SETUP typically makes two changes to your CONFIG.SYS file.  It
  places a "DEVICE=SETVER.EXE" statement at the beginning of your
  CONFIG.SYS file (before QEMM and puts "DOS=HIGH" at the end of
  the CONFIG.SYS. It will also put a "SHELL=COMMAND.COM" statement
  in the file if there is not one already.  For our purposes, you
  can leave that as it is.

  If you like, you can move the line that loads SETVER.EXE below
  the line that loads QEMM and run OPTIMIZE.  OPTIMIZE will take
  care of loading SETVER high. The default size of SETVER is .4K,
  so even if you leave it alone, it will not make a big impact on
  your memory.  Of course, if you don't have any programs that
  require it (run SETVER with no parameters to see the list), you
  can take it out entirely.

  Once you have installed the DOS 5 upgrade, you should switch to
  your QEMM directory and run the OPTIMIZE program.  Since the
  installation of DOS 5 will change your memory configuration,
  running Optimize will take care of any rearrangement of programs
  in upper memory that is necessary to give you the largest
  possible memory in DOS.

  If you are running DESQview, you should Optimize with the
  /STEALTH option, even though Optimize may not suggest it
  automatically.  DESQview can use the extra memory provided by
  Stealth ROM.

  INSTALLING QEMM OVER A DOS 5 SYSTEM:

  If you are installing QEMM onto a system that already has DOS 5,
  simply put the distribution disk in your floppy drive and run the
  INSTALL program.  The INSTALL routines are fully aware of DOS 5
  and will automatically run the Optimize program to configure the
  system optimally.  There is no need to do any "pre-configuration"
  to the system or to remove any of the DOS 5 memory management
  utilities.  If the Stealth ROM feature is needed to get your
  resident programs loaded into upper memory, Stealth ROM will be
  offered automatically by the Optimize program.

  As suggested above, if you are running DESQview you can force the
  Stealth ROM feature by running OPTIMIZE /STEALTH, since DESQview
  can use the extra memory provided by Stealth ROM.

  If you have any questions about whether your system is optimized
  or if you have added or removed any TSR's or drivers during the
  upgrade, check the "Hints" given by Manifest and re-run the
  OPTIMIZE program.

  Note:  In most cases, DESQview users get larger memory in their
  DOS windows by removing the "DOS=HIGH" from the CONFIG.SYS file.
  This allows DESQview to use the High Memory Area (HMA) that DOS
  would otherwise use. DESQview is more efficient at using the HMA
  than DOS, so giving DESQview the HMA usually results in more
  memory in your DESQview window.  The only way to be sure which is
  better is to try it both ways (running Optimize and then running
  DESQview's Memory Status program with each configuration) to
  determine which provides the most memory.

  MICROSOFT WINDOWS 3.x IN ENHANCED MODE:

  If you will be running Microsoft Windows in Enhanced mode and
  plan to use the DOS=HIGH parameter, you cannot use QEMM's "EXT="
  or "MEM=" parameters. When these parameters are used, Windows
  cannot properly take over management of the High Memory Area and
  will fail to start in Enhanced mode.  These parameters do not
  affect operation in Real or Standard modes, as QEMM remains in
  control of memory when those modes are used.  Further information
  concerning Windows 3.x and Quarterdeck products can be found in
  our technotes which are specific to Windows.

  COMPATIBILITY WITH EARLIER SOFTWARE

  The following are specific compatibility issues related to
  earlier versions of Quarterdeck software and the use of DOS 5.

  1)  If you use DOS 5's DOSKEY utility and run DESQview:

  You need DESQview 2.34 or later.  (Otherwise the DOSKEY utility
  will conflict with DESQview's DOS Services program if loaded
  before DESQview.)  To use DOSKEY in a DESQview DOS window, modify
  the "Program" line of the program information file using "Change
  a Program" to load "DOSKEY" and configure the "Parameters" line
  with "/REINSTALL" so that each DOS window will have its own,
  unique set of stacked commands.

  2)  To run Microsoft WINDOWS 3.x in Standard Mode inside
  DESQview:

  You need DESQview 2.34 or later.  Earlier versions of DESQview
  run Windows unreliably in Standard mode when DOS 5 is present.
  There is no problem running Windows Real mode if you have MS
  Windows 3.0.  (Real mode was discontinued with 3.1.)

  3)  If you run DOS 5's DOSSHELL program:

  The DOSSHELL program works fine with Quarterdeck's memory
  management software. It is also possible to start DESQview from
  the shell, however you cannot task switch away from versions of
  DESQview prior to 2.34 or the system will hang. DESQview versions
  2.34 and later prevent this problem; however, it is presumed that
  most users who use more advanced DOS environments, such as
  DESQview or Windows, will not be using DOSSHELL.

  4)  If you run DESQview and use SETVER.EXE:

  SETVER does not take effect when run inside DESQview 2.33 or
  earlier.  A list of the programs that require SETVER is available
  by typing "SETVER" at the DOS prompt.  If you have programs
  requiring SETVER and want to run them in DESQview, you should
  contact Customer Service for information about upgrading to the
  current shipping version.

  5)  If you run DESQview and get the message, "packed file is
  corrupt", when you open a window:

  The EXEPACK utility that came with versions of DOS prior to 5
  contained a bug that resulted in this error message being
  displayed when a packed .EXE file was executed in the first 64K
  of conventional memory. DOS 5 patches the files in memory so that
  they can be successfully unpacked and executed. However, since
  DESQview takes over much of the program-loading process from DOS,
  this patch does not take effect in DESQview versions prior to
  2.34. Again, upgrading your version of DESQview will take care of
  this problem.
