                         ■τWhat QEMM Setup Does

  QEMM Setup makes it easy to enable or disable QEMM's optional
  features, as well as add or delete QEMM's fine-tuning and
  troubleshooting parameters. QEMM Setup also provides you with
  hints on using QEMM and lets you view the QEMM READ.ME file for
  late-breaking information and technotes covering a variety
  of technical issues.  QEMM Setup can also assist you in
  troubleshooting any problems that might occur.

  QEMM Setup gives you help every step of the way.  When you select
  an option from a menu, you will see an explanation of what the
  option does. If you still have questions, just ask for help by
  pressing F1. If a topic has multiple help screens, you can press
  PgDn and PgUp to scroll through the help screens.
                        ■τHow to Use QEMM Setup

  To choose a Setup option, type its letter or use the arrow keys
  to highlight the option and press Enter. When you choose an item
  from the menu, a screen appears giving you information about the
  item.

  Also, at the bottom of each screen you will see a list of the
  keys you can use on that screen.

                    ■τSummary of QEMM Setup Options

   ■ΦReview or change QEMM parameters ■µ - lets you view or modify the
  current settings of certain QEMM device driver parameters. When
  you choose this item, you will see a list of the different
  options you can review and/or modify.

   ■ΦEnable or disable DPMI host ■µ - lets you enable or disable
  QEMM's DOS Protected Mode Interface (QDPMI) for programs that
  need DPMI services to run (e.g., Microsoft's C/C++ Development

                   ■Φ<<End of general help section>>

                         ■τHelp: QEMM Features

  Choose R on this screen if you want to review or change any QEMM
  parameters or features, or get more information about QEMM's
  options.  Also, choose R if you want to disable a feature that
  the Install program enables by default.  (You may also run the
  QSETUP program to review or change QEMM's options anytime after
  this installation.)

  Below is a description of various features that QEMM may enable:

   ■ΦDOS-Up ■µ frees up 7K-70K of conventional memory (depending on
  your configuration and DOS version) by moving parts of DOS into
  upper memory. By using DOS-Up, you will have more conventional
  memory for your programs.
                      ■τQEMM Features (Continued)

  If you use DESQview or DESQview/X and DOS version 5 or 6, you
  will probably get more memory in DESQview windows by removing the
  DOS=HIGH line that QEMM Setup adds to your CONFIG.SYS file.  You
  can remove DOS=HIGH as follows (you may want to jot down the
  keys to press in the steps below):

   1. Press  ■ΦR ■µ to change QEMM options. You will see a menu.
   2. Press  ■ΦU ■µ to select "Enable or disable DOS-Up."
   3. At the DOS-Up screen, press  ■ΦP ■µ to select "Partial."
   4. At the DOS-Up Options screen, press  ■ΦH ■µ to change
      DOS=HIGH to No.
   5. Press  ■ΦS ■µ to select "Save Configuration and Quit."
                      ■τQEMM Features (Continued)

  You need  ■ΦQDPMI ■µ if you are running a DOS-extended program
  that requires DPMI (such as Microsoft's C/C++ Development System
  for Windows v7, Borland's C/C++ v3, and Intel's Code Builder Kit
  v1.1).  Not loading the QEMM DPMI program saves about 2K of High
  RAM.  This feature may enable DESQview and DESQview/X users to
  run some Microsoft Windows applications in Windows standard mode
  in DESQview or DESQview/X, even though the applications normally
  run only in 386 enhanced mode.

   ■ΦStealth DoubleSpace ■µ saves about 40K of memory by moving
  MS-DOS 6's DoubleSpace driver outside of the first megabyte of
  memory. This selection appears only if you are using DoubleSpace.
  If Stealth Doublespace is disabled, the DoubleSpace driver takes
                      ■τQEMM Features (Continued)

  up 43K of High RAM or conventional memory.  You should not use
  Stealth DoubleSpace if you are using Vertisoft's SPACEMANager.

  If you have programs, utilities or drivers that use expanded
  memory (EMS), you will need an  ■ΦEMS page frame ■µ. You also
  need the page frame if you want to use QEMM's memory-saving
  Stealth ROM or Stealth DoubleSpace features. If you want to see a
  list of programs that use expanded memory, choose R, then H to
  view QEMM hints, then 6 for a discussion of the page frame.

                        ■τHelp: QEMM Parameters

  This menu lets you review or change the parameters on the
  QEMM386.SYS device driver line in the CONFIG.SYS file.  For
  more information about an option listed on the screen, type the
  option's letter or use the arrow keys to move the highlight bar
  to the option and press the Enter key.

  You will see a screen describing the parameter.  If a parameter
  has an abbreviation, it is listed in parentheses at the top of
  the screen.  If you want more information about the parameter
  press F1 for help.  Press PgDn and PgUp to scroll through help.

  Type E to edit the QEMM device driver line directly, A to accept
  the changes you have made, or the Esc key to cancel your changes
                  ■τHelp: QEMM Parameters (Continued)

  and return to the main menu.  The PgUp and PgDn keys show you
  QEMM options on previous and following screens.

  Note: If you are using an optional parameter file, parameters in
        that file will not be changed.

             ■τHelp: Fill Upper Memory with RAM - RAM

  The RAM parameter creates High RAM in the upper memory area. When
  High RAM is present, you can load TSRs, device drivers and parts
  of DOS into upper memory.  By loading these items into upper
  memory, you will have more conventional memory available for DOS
  programs.

  The default QEMM installation places the RAM parameter on the
  QEMM386.SYS line in the CONFIG.SYS file.

                 ■τHelp: Copy ROMs with RAM - ROM

  If your system does not already speed up ROMs by copying them
  into faster RAM, the ROM parameter may speed up some system
  operations, particularly writes to the screen by programs that
  use BIOS or DOS video calls (like DOS's COMMAND.COM).

  The ROM parameter does diminish QEMM's memory pool by the amount
  of memory taken up by your ROMs - usually about 96K.

  Note that floppy disk drives may malfunction on a few systems if
  the ROM code that controls the floppy disk drives is speeded up
  by the ROM parameter.

   ■τHelp: Do not Stealth a particular ROM - EXCLUDESTEALTH (XST)

  If you give the starting address of a ROM on this screen, QEMM
  Setup will place the XST=xxxx parameter on the QEMM386.SYS line
  in your CONFIG.SYS file, causing QEMM not to Stealth that ROM.

  You should tell QEMM not to Stealth a particular ROM only when
  attempting to solve problems with the Stealth ROM feature.  If
  possible, it is usually more memory-efficient to solve Stealth
  ROM problems with the EXCLUDE parameter than with the
  EXCLUDESTEALTH parameter.  See the STEALTH.TEC technote in the
  \QEMM\TECHNOTE directory for details on how to troubleshoot
  Stealth ROM problems.
             ■τDo Not Stealth a Particular ROM (Continued)

  You can get the starting addresses of all Stealthed ROMs from the
  Manifest QEMM Overview screen.  In general, video ROMs are
  located at C000 (or at E000 on Micro Channel systems); system
  ROMs at F000.  If you have a disk ROM (many systems do not), it
  will generally be located at an address between C800 and E000.

          ■τHelp: Reclaim Unused Shadow Memory - SHADOWRAM (SH)

  By default, QEMM recovers unused shadow memory on systems where
  QEMM recognizes the type of shadow memory in use.  This feature
  typically adds about 192K of RAM to QEMM's memory pool.
  Manifest's QEMM Memory screen will include a Shadow RAM row if
  QEMM is reclaiming shadow memory on your system.

  On some systems with unusual types of shadow memory, QEMM may
  have a problem reclaiming the unused portion.  A common symptom
  is continual rebooting when QEMM loads, although other symptoms
  can occur.  Disabling the shadow memory feature is a common
  troubleshooting technique.  When you do so, QEMM Setup adds
  the SH:NONE parameter to the QEMM386.SYS device line.  For more
  information, see SHADOWRAM in Chapter 7 of the manual.

               ■τHelp: Find ROM holes - ROMHOLES (RH)

  If you are not using Stealth ROM, QEMM tries to find unused areas
  in the system ROM (between F000 and FFFF) that can be used for
  High RAM or expanded memory mapping.  If you choose N on this
  screen, QEMM Setup disables this feature by putting the RH:N
  parameter on the QEMM386.SYS device line.

  The most common reason to disable this feature is to troubleshoot
  floppy disk problems or other problems with QEMM on your system.
  If the RH:N parameter solves your problem, it may be more
  memory-efficient to use the EXCLUDE parameter on a section of
  the system ROM instead of using the RH:N parameter.  For more
  information, see the description of the ROMHOLES parameter in
  Chapter 7 of the manual.

  ■τHelp: Enable suspend/resume laptop support - SUSPENDRESUME (SUS)

  Suspend/Resume is a feature built into many laptop and notebook
  systems that allows you to run the computer on low power when it
  is not in use and to restore the system to its previous state
  when you return to it.  Without special support, many systems
  will not return properly from a low power state if a 386 memory
  manager such as QEMM is active.

  If you choose No on this screen, QEMM can automatically support
  the Suspend/Resume feature on a few known systems.

  If your system has a Suspend/Resume feature that is not working
  properly with QEMM installed, choose Yes on this screen to have
           ■τEnable Suspend/Resume Laptop Support (Continued)

  QEMM Setup place the SUS parameter on the QEMM386.SYS line in
  the CONFIG.SYS file.  This parameter makes QEMM search for the
  hardware interrupt that Suspend/Resume is using.

  If your Suspend/Resume feature still does not work after you have
  rebooted with the SUSPENDRESUME parameter, you can try explicitly
  telling QEMM how to support Suspend/Resume by placing the number
  of a hardware interrupt in the field on this QEMM Setup screen.
  QEMM Setup will then specify QEMM386.SYS's SUS:xx parameter,
  where xx is the hardware interrupt number.  2, D, 72, 73, and 77
  are the numbers most likely to be used by the Suspend/Resume
  feature.  Consult your system's manual or the manufacturer for
  more information on the correct number to use.

             ■τHelp: Reclaim Top Memory - TOPMEMORY (TM)

  By default, QEMM reclaims unused top memory on Compaqs and other
  systems where QEMM recognizes the presence of top memory.  This
  feature typically adds 256K to 384K of RAM to QEMM's memory pool.
  Manifest's QEMM Memory screen will include a Top Memory row if
  QEMM is reclaiming top memory on your system.

  If QEMM has a problem reclaiming top memory on your system, you
  may experience a hang or reboot when QEMM386.SYS loads. If you
  choose not to reclaim top memory, QEMM Setup adds the TM:N
  parameter to the QEMM386.SYS device line.  For more information,
  see the TOPMEMORY parameter in Chapter 7 of the manual.

                     ■τHelp: Edit QEMM Device Line

  If the QEMM parameters do not fit in the visible field on screen,
  an arrow at the left or right of the field indicates the presence
  of off-screen parameters. The field will scroll when you use the
  arrow keys or type.

               ■τHelp: Set Size and Type of Disk Buffer
                  ■τDISKBUF (DB) & DISKBUFFRAME (DBF)

  QEMM can intercept all disk reads and writes with the DB=xx
  parameter (Type=D).  This type of disk buffering eliminates
  problems with bus-mastering hard disks, but with a penalty in
  disk performance.

  Alternately, QEMM can intercept only disk reads and writes into
  and out of the page frame with the DBF=xx parameter (Type=F).
  This type of buffering may resolve conflicts between some
  expanded memory-using disk utilities and Stealth.
             ■τSet Size and Type of Disk Buffer (Continued)

  If you let QEMM try to determine whether you need a disk buffer,
  it will create a 2K "DISKBUF-type" buffer if it detects a bus-
  mastering conflict with the drive from which QEMM loads (Type=A).

  You can also prevent QEMM from creating a disk buffer even if it
  thinks you need one (Type=N).

  If you choose type D or F, you can set the size of the disk
  buffer.  A bigger buffer uses more memory but may improve disk
  performance.  2 and 10 are commonly used values.

            ■τHelp: Relocate Extended BIOS Data Area (XBDA)

  By default, QEMM moves the extended BIOS data area (XBDA) into
  High RAM unless it detects that you have a Suspend/Resume
  feature, or unless you place the SUSPENDRESUME (SUS) parameter on
  the QEMM386.SYS line in CONFIG.SYS.  In these last cases, QEMM
  moves the XBDA into low conventional memory so that the
  Suspend/Resume feature will work.

  If the XBDA remains at the top of conventional memory, it will
  prevent video filling or the use of VIDRAM and will decrease the
  size of windows in DESQview and DESQview/X.  Moving the XBDA into
  High RAM lets VIDRAM and video filling work, increases the size
  of windows in DESQview & DESQview/X, and saves 1K of conventional
             ■τRelocate Extended BIOS Data Area (Continued)

  memory.  Moving the XBDA to low memory does not save conventional
  memory but gives all the other benefits listed above.

  You should choose N on this screen if you have a system or a
  program that expects the XBDA to be at the top of conventional
  memory.  The symptom of this problem is usually a system crash,
  which can occur at boot time or later.  Choosing L gives most of
  the benefits of moving the XBDA, and so is a less drastic way to
  try to solve your XBDA-related problem than choosing N.  You can
  choose H (to save 1K of conventional memory) if QEMM is loading
  your XBDA low. If you do this on a laptop PC that has a
  Suspend/Resume feature, Suspend/Resume may or may not work
  properly.
             ■τRelocate Extended BIOS Data Area (Continued)

  To find out where your XBDA is loaded, see Manifest's First Meg
  BIOS Data screen.  If the third line on this screen does not say
  "0E: Extended BIOS Segment," then you do not have an XBDA.

  If you do have an XBDA, check the four-digit hexadecimal address
  of the XBDA.  If this address is 9FC0, then the XBDA has not been
  moved at all.  If the address starts with 0 or 1, the XBDA has
  been moved to low conventional memory.  If the address starts
  with a letter (A through F), then the XBDA is in High RAM.

                ■τHelp: Reserve Video Area for VIDRAM
               ■τVIDRAMEGA (VREGA) & VIDRAMEMS (VREMS)

  When you invoke VIDRAM with the VIDRAM ON command, you extend
  conventional memory for DOS text-based programs. However, you
  cannot use EGA or VGA graphics while VIDRAM is on. If you have an
  EGA/VGA color system, VIDRAM can usually increase the size of
  conventional memory by 64K.

  If you choose G on this screen, the VREGA parameter will be
  added to the QEMM386.SYS device driver line.  This parameter
  prevents QEMM from creating High RAM in unused video areas, and
  allows VIDRAM ON to extend conventional memory by 96K instead of
  64K, though the total amount of High RAM on your system will
  usually decrease by 32K.
              ■τReserve Video Area for VIDRAM (Continued)

  If you are a DESQview user, and you want to extend conventional
  memory in all DESQview windows, you should choose M on this
  screen to activate the VREMS parameter, then start VIDRAM
  with the VIDRAM ON EMS command. Without the VREMS parameter,
  programs that run in DESQview in expanded memory windows
  will not get the benefits of VIDRAM.  Like VREGA, VREMS will
  cause VIDRAM to extend conventional memory by 96K instead of 64K,
  at the cost of 32K of High RAM.

  You can also choose M if you are a DESQview/X user, and you have
  DESQview/X set up to use 8514a graphics. In this case all your
  DESQview/X windows will be extended by 96K, and you will still be
  able to use 8514a graphics.  If, however, you plan to run
              ■τReserve Video Area for VIDRAM (Continued)

  programs inside DESQview/X that use EGA or VGA graphics (instead
  of 8514a graphics), you must choose N and forego the use of
  VIDRAM.

  For more information on VIDRAM see Chapter 6 of the QEMM manual.
  For more information on the VIDRAMEGA and VIDRAMEMS parameters,
  see Chapter 7.


     ■τHelp: Remove or Set Address of Page Frame - FRAME (FR)

  The EMS page frame is a 64K area, usually in upper memory, used
  by device drivers, TSRs and applications to access expanded
  memory. QEMM also uses the page frame to enable its Stealth ROM
  and Stealth DoubleSpace features.

  The AUTO selection tells QEMM to choose the page frame address
  based on your system configuration. The NONE selection eliminates
  the page frame--this will disable Stealth features and make
  expanded memory unavailable for programs. If you do not use
  Stealth or programs that use EMS, eliminating the page frame will
  make 64K of upper memory addresses available for High RAM.
           ■τRemove or Set Address of Page Frame (Continued)

  You can also specify the starting segment address of the page
  frame if a different location will consolidate two smaller High
  RAM regions into one large one, or if you need to place the page
  frame at the starting address of one of your ROMs to make the ROM
  work with the Stealth ROM feature.  However, you should not set
  the page frame address if you do not know how to avoid conflicts
  between the page frame and ROM, adapter RAM, or video ROM.

    ■τHelp: Stealth System and Video ROMs - STEALTHROM (ST)

  The Stealth ROM feature can typically free 48-115K of upper
  memory addresses which can then be used for High RAM or
  expanded memory mapping.

  If you select M (Stealth Mapping), QEMM Setup will add the ST:M
  parameter to the QEMM386.SYS device line; this instructs
  Stealth to use its mapping method, which frees the most upper
  memory addresses.  If you select F (Stealth Frame), QEMM Setup
  will add the ST:F parameter; this instructs Stealth to use the
  frame method, which frees less upper memory but is compatible
  with more ROMs than the mapping method is.  QEMM Setup will not
  implement the Stealth ROM feature if you type O for Stealth Off.
              ■τStealth System and Video ROMs (Continued)

  QEMM offers to enable Stealth ROM during the installation
  process or the Optimize process if it sees that you need
  additional High RAM.  If you use DESQview or DESQview/X,
  you should use the Stealth ROM feature even if QEMM has not
  enabled it for you.

  If you ever encounter problems with Stealth ROM, see the
  STEALTH.TEC technote in the \QEMM\TECHNOTE directory.

                 ■τHelp: Set Up QEMM for Troubleshooting

  If you wish to troubleshoot a particular problem, you can setup
  QEMM for troubleshooting. When you enable the troubleshooting
  parameters, QEMM Setup will place the following nine parameters
  on the QEMM386.SYS line in CONFIG.SYS:

         ■ΦDB=2 SH:NONE TM:N TR:N CF:N FILL:N MR:N RH:N XBDA:N.

  These are not the only QEMM386.SYS parameters that can solve
  problems, but they are the easiest to try as part of a one-step
  troubleshooting process.  If your problem goes away after you
  enable the troubleshooting parameters, you should try eliminating
  the parameters one by one until you find the parameter that
              ■τSet Up QEMM for Troubleshooting (Continued)

  solved the problem, then take all the other troubleshooting
  parameters off the QEMM386.SYS line.  Be sure to reboot whenever
  you add or delete parameters. See Chapter 7 of the QEMM manual
  for more information on the individual parameters.

                     ■τHelp: WINDOWS and QEMM Setup

  QEMM Setup looks for Microsoft Windows on your hard disk so that
  it can add the statement SystemROMBreakPoint=false to the 386Enh
  section of the Windows SYSTEM.INI file.

  This enables QEMM to use the F000-FFFF region (usually occupied
  by the System ROM) for High RAM or expanded memory mapping when
  Windows is in 386 enhanced mode.

  If you already have this statement in your SYSTEM.INI file, QEMM
  Setup will not change SYSTEM.INI.

                             ■τHelp: QDPMI

  This selection lets you enable or disable the DOS Protected Mode
  Interface for programs that support DPMI (e.g., Microsoft's C/C++
  Development System for Windows version 7, Borland's C/C++ version
  3, and Intel's Code Builder Kit version 1.1).  QDPMI may enable
  DESQview and DESQview/X users to run some MS Windows applications
  in Windows standard mode in DESQview or DESQview/X, even though
  the applications normally run only in 386 enhanced mode.

  If you choose Y, QEMM Setup will place the QDPMI.SYS line in your
  CONFIG.SYS file.  QDPMI.SYS takes less than 2K of memory, and
  can be loaded into High RAM.  If you choose N, QEMM will not
  provide DPMI services. Protected-mode programs that are VCPI
  clients will run under QEMM even if QDPMI is not loaded.
                         ■τHelp: DPMI Swap Size

  DPMI Swap Size specifies how much disk space should be reserved
  for a virtual memory swapfile for a DPMI application.

  The advantage of specifying a bigger swapfile is that more
  virtual memory will be available to DPMI programs.  It is
  particularly important to have a large swapfile if you have a
  low-memory system and a memory-hungry DPMI application.  The
  disadvantage of specifying a bigger swapfile is that more of your
  hard disk may be used up by your DPMI program.

  Note that QDPMI does not use any of your hard disk for a swapfile
  until the DPMI program requests the memory, and the swapfile
  grows as needed up to the maximum size that you set.

                         ■τHelp: DOS-Up Feature

  The DOS-Up feature takes parts of DOS that would normally remain
  in conventional memory and moves them into upper memory. If you
  are using the DOS=HIGH command that is part of DOS 5 and DOS 6,
  DOS-Up acts on the parts of DOS that are not affected by
  DOS=HIGH.

  For information on using DOS-Up with DR DOS 6, see the technote
  DRDOS6.TEC in the \QEMM\TECHNOTE directory. You can view this
  technote using a text editor. You can also view technotes by
  using the selection "View QEMM hints, technotes and READ.ME" on
  the QEMM Setup menu.
                      ■τDOS-Up Feature (Continued)

  DOS-Up makes three changes to your CONFIG.SYS file. DOSDATA.SYS,
  which loads at the beginning of the CONFIG.SYS, prepares the
  system for DOS-Up.  DOS-UP.SYS loads the DOS kernel, data, and
  resources into High RAM.  And your SHELL statement is modified so
  that LOADHI.COM can put COMMAND.COM in upper memory. If you have
  no SHELL statement, DOS-Up creates one for you.

  Parts of DOS that can be moved out of conventional memory are:

   ■ΦDOS resources ■µ (FILES, BUFFERS, FCBS, STACKS, LASTDRIVE). The
  amount of memory that these resources take up varies with your
  configuration.  See Manifest's DOS Overview screen for details.
                      ■τDOS-Up Feature (Continued)

   ■ΦCOMMAND.COM ■µ (the DOS command processor).  Its size varies in
  different versions of DOS.  It is normally smaller than 5K.

   ■ΦDOS data ■µ (the parts of the DOS kernel that are not moved out
  of conventional memory by the DOS=HIGH statement).  If you are
  using DOS=HIGH, these parts will be around 5.5K in size. If you
  are not using DOS=HIGH, these parts will be considerably larger;
  they are normally around 41K.

   ■ΦDOS=HIGH ■µ is a statement in CONFIG.SYS that tells DOS to load
  much of itself into the HMA (the High Memory Area--the first 64K
  of extended memory).  This option is available only if you are
  using DOS 5 or 6 (and is not available for DR DOS 6 users).
                      ■τDOS-Up Feature (Continued)

  The amount of DOS that moves into the HMA with DOS=HIGH depends
  on your configuration, but it is generally more than 40K.

  The most common reason not to enable the DOS=HIGH feature is if
  you run a program that uses the HMA more efficiently than DOS,
  like DESQview or DESQview/X. By eliminating the DOS=HIGH
  statement in CONFIG.SYS you may be able to have more available
  memory inside DESQview and DESQview/X windows.  For information
  on maximizing the memory inside DESQview and DESQview/X windows,
  select "View QEMM hints and tips and READ.ME" on the QEMM Setup
  menu. When the next menu displays, select "QEMM and DESQview or
  DESQview/X."

                  ■τHelp: Stealth DoubleSpace Feature

  QEMM can use its Stealth technology to move the DoubleSpace
  driver entirely out of conventional and upper memory, making it
  appear in the EMS page frame when it is needed.  This saves about
  40K that would otherwise use up space in conventional memory or
  upper memory.

  If you enable Stealth DoubleSpace, QEMM Setup will place the
  ST-DBL.SYS driver in your CONFIG.SYS file to relocate the
  DoubleSpace driver.  ST-DBL.SYS uses about 3K and can be loaded
  high.  Optimize will add the necessary command to load this driver
  high if there is room for it in upper memory.

               ■τHelp: Multiple CONFIG.SYS Configurations

  QEMM Setup has detected that your CONFIG.SYS file contains
  multiple configuration paths.  Because the QEMM386.SYS device
  driver may be in more than one of these paths, you need to tell
  QEMM Setup which path to modify, in the event that you decide to
  make changes to a QEMM386.SYS device line.

  You can choose any of the configuration paths listed on screen,
  or you can choose C to create a new configuration path based on
  one of your existing QEMM386.SYS configuration paths.  If you
  choose C, QEMM Setup will prompt you for the existing path, and
  then for a name for the new path that it has created.  The name
  can be up to 32 characters long and can consist of more than one
  word.  After you create a new configuration path, you should
            ■τMultiple CONFIG.SYS Configurations (Continued)

  run Optimize and select the new configuration path.

  If you choose C, and if your AUTOEXEC.BAT file uses the "GOTO
  %CONFIG%" statement to branch to different labels, you may want
  to modify your AUTOEXEC.BAT to customize it for the new
  configuration path that you have created.  By default, QSETUP
  modifies AUTOEXEC.BAT (if necessary) to make sure that the new
  configuration path and the existing one that it was based on will
  execute the same commands in AUTOEXEC.BAT.

                       ■τHelp: HIMEM.SYS and QEMM

  QEMM Setup has detected the XMS memory manager HIMEM.SYS in
  your CONFIG.SYS file.  QEMM is, among other things, an XMS
  manager, and so you should normally tell QEMM Setup to remove
  HIMEM to save the memory that it uses (typically 1-3K).  If you
  leave HIMEM in your CONFIG.SYS, QEMM will still be able to
  control all the system's memory and function normally.

  The one instance in which you might leave HIMEM in the CONFIG.SYS
  is if your system contains more than 16 megabytes of memory, and
  your version of HIMEM knows how to find all the memory even
  though the system does not report it through standard BIOS calls
  (Compaqs with over 16MB of RAM are the most notable example).
                    ■τHIMEM.SYS and QEMM (Continued)

  In this case, HIMEM should be loaded before QEMM386.SYS, which
  can allocate all the system's memory from HIMEM.  If you have a
  Compaq with over 16MB of RAM, use the HIMEM.EXE driver provided
  by Compaq and be sure to add the /ABOVE16 parameter to the device
  driver line.  If you have MS-DOS 6, you can alternatively use
  DOS's HIMEM.SYS without a parameter.  Without such a version of
  HIMEM, QEMM will only find all the memory on the system if you
  add the USERAM=xxxx-yyyy parameter with an appropriate address
  range to the QEMM386.SYS line in CONFIG.SYS.

                    ■τHelp: QEMM Setup Complete

  QEMM Setup has made changes to your CONFIG.SYS file that may
  require that you run the Optimize program. Optimize is a program
  that determines how to load TSRs, device drivers and selected
  parts of DOS into upper memory.

  Optimize analyzes the memory requirements of device drivers and
  TSRs that you are loading from CONFIG.SYS, AUTOEXEC.BAT and any
  batch files called by AUTOEXEC.BAT. Then, Optimize determines the
  most efficient way to load items into High RAM by testing all
  possible locations (there can be thousands or millions of
  possibilities). The object is to free up as much conventional
  memory as possible for your DOS programs. If you are using QEMM's
                   ■τQEMM Setup Complete (Continued)

  DOS-Up feature, Optimize also experiments with different ways of
  loading parts of DOS into upper memory.

  If you type O, QEMM Setup will start the Optimize process
  immediately.  If you hit Enter, you will exit QEMM Setup without
  running Optimize; you can then run Optimize manually by typing
  OPTIMIZE.  If you do not run Optimize before rebooting the system,
  you may see LOADHI error messages when you next boot, and some
  of your TSRs and drivers may either load low or malfunction.
