  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 you can obtain the unabridged version from the following
  sources:

  Subject: A general, easy-to-follow, and efficient guide to
  troubleshooting problems with QEMM 7.0.

  This is a very general guide to troubleshooting QEMM, and
  provides either quick fixes or references for additional
  information.  See the Appendix for information on obtaining
  technical bulletins discussed in this document.

  PLEASE NOTE:  The information contained in this technical
  bulletin pertains ONLY to QEMM version 7.0.  If you require
  information relating to earlier versions of QEMM, you should
  obtain the longer, unabridged version through our standard
  support channels.

  Exception 13 errors can occur for a wide variety of reasons,
  almost all of which are addressed here.  If you wish to learn
  more about the causes of Exception 13 errors, refer to the
  technote EXCEPT13.TEC; for detailed troubleshooting, refer to
  EX13FLOW.TEC.

  There is a line in your CONFIG.SYS that reads:

    DEVICE=C:\QEMM\QEMM386.SYS [parameters]

  Steps 1-6 in this technote involve editing the [parameters] on
  this line, and nothing else.  Every time you change the
  parameters on this line, you must re-boot your computer for them
  to take effect.

  1)  Remove QEMM by placing the word "rem" before the word
  "device" on this line; re-boot.  If this does not solve your
  problem, QEMM is not involved.  If this does solve your problem,
  remove the "rem".

  2)  If there is a Stealth parameter ("ST:M" or "ST:F"), remove it
  and reboot. If this solves your problem, refer to our technote
  STEALTH.TEC and follow its instructions.

  3)  Add the parameter "DB=2" to this line and re-boot.  If this
  solves your problem, refer to our technote BUS-MAST.TEC for an
  explanation.

  4)  Add the parameter "X=A000-FFFF" to this line and re-boot.  If
  this solves your problem, refer to our technote "EXCLUDE.TEC" and
  follow its instructions.

  5)  Remove all the parameters on the QEMM386.SYS line.  Add the
  following ALL ON THE SAME LINE:

  DB=2 DMA=128 IOTRAP=64 LD FILL:N CF:N VDS:N MR:N RH:N SH:N
      TR:N XBDA:N UX ON

  then reboot.  If this set of parameters solves your problem,
  consult the manual for an explanation of the meaning of these
  parameters.  All of these parameters, even taken together, do not
  seriously handicap the usefulness of QEMM.  All together, they
  cause QEMM to use only 2K more conventional memory, 116K more
  extended memory, and will not cause QEMM to be any slower.  You
  can find the one(s) you need by eliminating them, one at a time.

  6)  If you are still experiencing the problem, add the parameter
  EMS:N and re-boot. If this solves your problem, some program that
  uses expanded memory is probably misbehaving, since this
  parameter causes QEMM to cease providing expanded memory.  Go to
  step 7, and check to see if the other program involved uses EMS.

  7)  Rename your AUTOEXEC.BAT to TEST.BAT.  Make a backup copy of
  your old CONFIG.SYS by typing:

         COPY CONFIG.SYS CONFIG.XXX

  Edit your CONFIG.SYS so that it contains ONLY the QEMM line and
  "FILES=40", then reboot your computer.  If this solves the
  problem, restore your old CONFIG.SYS and AUTOEXEC.BAT files one
  line at a time to find out what other program is causing your
  problem.

  8)  If you are not able to solve your problem using these
  techniques and referenced technical bulletins, contact Technical
  Support by voice (310-392-9701), FAX (310-314-3217) or our
  Technical Support BBS (310-314-3227.)  If you have solved your
  problem but are unsure of the consequences of using the
  parameters needed to solve it, you may want to contact Technical
  Support for further information.

                               APPENDIX

  Many of the technical bulletins discussed in this document were
  installed in your QEMM\TECHNOTE directory when you installed QEMM
  7.0.  Those which are not included with QEMM can be obtained from
  the Quarterdeck BBS (310-314-3227), by calling QFAX (our
  automated FAX-back service, at 310-314-3214), on CompuServe (go
  QUARTERDECK, library 2), or BIX.  Many technotes are also
  available on large local BBSs, often in "DESQview" or
  "multitasking" file areas.
