  DOS Utilities
  =============

   How To Run DOS Install
   ----------------------
   Before running Install, please make sure you have at least 20 file
   handles in your CONFIG.SYS.  Add this line to your CONFIG.SYS if
   not already present:

      FILES=20

   Then put the diskette that has the DOS utilities into your floppy
   drive, and at the command prompt from your floppy drive, type:

      INSTALL

   followed by carriage return.  Follow the instruction on the screen
   to complete the installation.

   DOS Mouse Driver, Release 6.20
   ------------------------------
   Mouse support for standard VESA super VGA mode has been added for
   this release.  The modes supported are modes 100(hex) through
   10C(hex), and mode 6A(hex).

   The appropriate files will be automatically installed if the mouse
   installation program detects a VESA BIOS extension, release 1.00
   or higher, or a VGA adapter.

   The DOS driver is made up of the following three files:

      1) MOUSE.COM    : mouse driver
      2) LMOUSE.INI   : mouse driver configuration file
      3) LVESA.OVL    : video module for the DOS driver

   These files must be in the same directory.  However, the
   configuration file and the video module are not required -- if any
   one (or both) is missing, MOUSE.COM will still load, but super VGA
   video modes will not be available.  As for MOUSE.SYS, VESA super VGA
   modes are not supported at this time, and LMOUSE.INI and LVESA.OVL
   are not required.

   The configuration file is automatically created by the installation
   program for your specific hardware configuration.  We recommend that
   you do NOT modify it.  In case you change your video adapter, we
   suggest that you reinstall the mouse software to update the
   configuration file.

   If you happen to have a MOUSE environment variable in your
   AUTOEXEC.BAT that does not point to the installed mouse directory,
   e.g.:

      SET MOUSE=DRIVE:\DIFFERENT_PATH;

   please remove it.  It could cause the DOS mouse driver not being
   able to find LMOUSE.INI if it is set incorrectly.

   How To Upgrade Your Mouse DOS Files
   -----------------------------------
   If you are upgrading from a previous version of Mouse software, we
   recommend that you install your Mouse Software in the same directory
   as your previous version.
   The INSTALL program replaces the old software in the MOUSE directory
   with the new versions.

   How To Install Your Mouse For The GEM Environment
   -------------------------------------------------
   When installing GEM, select the option for Logitech Mouse or
   choose the selection for "MOUSE.COM".

   How To Install Your Mouse For AutoCAD 10 And Above
   --------------------------------------------------
   When installing AutoCAD, choose the Microsoft serial or Bus mouse
   selection.  This selection will use the mouse driver in memory.

   How To Install Your Mouse For DOS 4.0 Shell Program
   ---------------------------------------------------
   IBM DOS 4.0x installation places a new AUTOEXEC.BAT file in the
   root directory and a DOSSHELL.BAT file in the DOS files directory.

   In order to use your mouse with the mouse driver in memory, you
   must modify both the AUTOEXEC.BAT and DOSSHELL.BAT files.

   1) With a text editor, open the DOSSHELL.BAT file and find this
      statement:

      "@SHELLC /MOS:[driver].MOS/TRAN/COLOR/ etc...."
      (where [driver] can be PCIBMDRV, PCMSDRV, or PCMSPDRV)

   2) Delete "/MOS:[driver].MOS" from the "@SHELLC" statement.  Leave
   the rest of the statement.  The modified statement should now
   look like this:

      "@SHELLC /TRAN/COLOR/ etc...."

   3) Modify your AUTOEXEC.BAT file:
      Include the C:\MOUSE sub-directory in the PATH statement.  Load
      MOUSE before you execute DOSSHELL.

   This lets you use your Mouse both inside and outside the Shell for
   DOS 4.0x.

   How To Install Your Mouse For DOS 5.0 Shell Program
   ---------------------------------------------------
   The DOS mouse driver should be loaded prior to the DOS 5.0 DOSShell
   and not within a DOS box.  Also Windows 3.x should not be launched
   from a DOS 5.0 DOSShell.  This may result in loss of mouse
   functionality under Windows 3.x.

   Loading The Mouse Driver High
   -----------------------------
   In case you have problems trying to load the mouse driver high, you
   can load the driver without the VESA video overlay with the
   following command:

   For DOS 5.x:      LOADHIGH MOUSE NOVCI

   For the mouse driver to load in high memory it must have enough
   memory to load straight from disk.  The mouse drivers size on disk
   is at least 40K.  The room needed to load from disk into high
   memory must be at least 40K.

   Once the driver has initialized it frees a large portion of
   memory.  The remaining size in memory is 17K to 22K.

   All programs that are loaded high must be loaded into memory
   with their full size intact.

   Sometimes the loading order can make a difference.  If the
   mouse driver is loaded first and smaller programs are loaded
   last then the driver would load high properly.

   Some load high parameters, such as QEMM386's /H (Happy) parameter,
   may not allow the LVESA.OVL to be loaded.  You will receive the
   following message if LVESA.OVL is unable to load:

      'Error: Not enough memory to load the video module'

   Other load high programs may not allow LVESA.OVL to load at all. If
   this occurs and LVESA.OVL is required, the mouse driver must be
   loaded in low DOS memory.

   How To Install Your Mouse For OS/2
   ----------------------------------
   If you intend to use your mouse with OS/2 version 1.X, please refer
   to the following table for the proper selection of mouse to make
   during the installation of OS/2:

   Mouse Commands For Serial Mouse (C Model Only)
   ----------------------------------------------
   By default, your mouse driver configures your serial mouse to the
   following parameters:
      Serial Port (COM)          1
      Baud Rate               2400
      Ballistic                Low
      Sensitivity                5
      Report Rate              150
      Number of buttons          3
      Protocol           MM Series

   Note: the serial port default 1 is also available on the M device.

   If your application requires you to change the setting(s) of your
   serial mouse (C model) for one or more of the above parameters, use
   the following commands:

   MOUSE [#]
      Loads the mouse driver into memory and configures it to
      COM port, where # is either 1, 2, 3, or 4.

   MOUSE [baud rate]
      Loads the mouse driver into memory and configures the
      baud rate for the mouse to 1200, 2400, 4800, or 9600.

   MOUSE [report rate]
      Loads the mouse driver into memory and configures the
      report rate for the mouse to 10, 50, or 150 (continuous).

   MOUSE [protocol]
      Loads the mouse driver into memory and configures the
      protocol for the mouse to 5B, MM, or RE.

      5B: Five byte packed binary
      MM: MM series
      RE: Relative bit pad one

   MOUSE ?
      Displays the current mouse driver and button settings.

   MOUSE INIT
      Resets the mouse driver to its initial settings.

   MOUSE PC
      Sets the mouse driver to emulate an MSC Tech. PC Mouse.

   How To Install Your Windows 3.x Drivers
   ---------------------------------------
   Windows 3.x should be on your system prior to the DOS installation.
   Take note of the drive and path name of Windows (e.g. C:\WINDOWS.)
   This will be used during the DOS Mouse Software installation.
   Windows drivers will be loaded during the DOS Mouse Software
   Installation.
   To install these drivers, choose the entry "Install Mouse Driver
   for Windows 3.x" in the Main Menu and follow the on-screen
   instructions.

   Note: If you did not install the Windows mouse driver under
   Windows 3.0 then you would have multiple "Logitech" entries in the
   mouse selection menu.  To solve the problem, choose the entry
   "Install Mouse Driver for Windows 3.x" in the Main Menu and follow
   the on-screen instructions.
