INSTALLING OVER EXISTING TABLET DRIVERS
---------------------------------------
If you have previously installed tablet drivers on your system, you
must remove them and reboot your computer before attempting to install
the SummaSoft drivers.  The 'Remove' option in Setup will only remove
previously installed Summagraphics tablet drivers. For instructions on
removing drivers for a tablet manufactured by another company, you
should refer to the documentation supplied with that tablet.


BASIC INSTALLATION PROCEDURE
----------------------------
All tablet drivers are installed using the Summagraphics SETUP program 
provided on the tablet drivers diskette.  The SETUP program will
also allow you to install your drivers in a directory of your own
choosing, and as mentioned before can be used to remove existing 
Summagraphics Windows NT drivers.

Please read the other sections of this document specific to the driver(s)
you wish to install before doing the installation.

After you have connected your tablet to your computer's serial port and 
connected the tablet power supply, follow this procedure to install or
remove drivers:

  - Boot up Windows NT.  

  - Close all open applications, and disable any active Virus Detection 
    software.

  - Insert the Summagraphics driver diskette into your computer.  

  - In the Program Manager window type ALT-F, R(un), A:\SETUP
    (or B:\SETUP), and then press Enter.  
    
  - Follow the instructions presented on the computer screen. The
    Summagraphics SETUP program allows you to selectively install or 
    remove any or all of the available drivers for your tablet.  When
    the driver selection screen is presented, be sure to mark only those
    drivers you wish to install or remove.

Note: The cordless pointing devices automatically deactivate themselves
      after a few minutes of non-use.  Simply press button one on the
      pointing device to reactivate the device.  Button one is the tip on
      the pen.


REMOVING THE NT DRIVERS
-----------------------
The drivers must be removed using the Summasoft SETUP program. This will
automatically remove all driver files and associated Registry entries.
You must reboot your computer to complete the removal process.


NOTES ON NT 3.51 SERVICE PACKS
------------------------------
Fix for cursor sluggishness under NT 3.51 following an install of any NT
Service Pack.  This fix replaces the version of CSRSRV.DLL installed by
any Service Pack, with the original CSRSRV.DLL from the 1057 build of
NT 3.51.


For this fix you will need the original 3.51 NT CD-ROM or Floppy Set.


- From a DOS prompt under NT, see if EXPAND does in fact exist on the
  hard disk. This can be easily done by typing EXPAND and hitting <enter>,
  which will give the copyright header and the "no files specified" error
  warning.

- If it does exist, it needs to be v2.50 or better to work. If it's an
  older version, then it must be copied from the CD or Floppy set to the
  HD, specifically to the NT \SYSTEM32 directory.


1) From a DOS prompt under NT, expand the CSRSRV.DL_ file on your original
   NT 3.51 CD or floppy to some temporary location on the HD. For example:

           EXPAND CSRSRV.DL_ C:\CSRSRV.DLL

   It is not recommended that the \TEMP directory be used, as this directory
   tends to get purged when you least expect it.

2) Exit the DOS box, exit NT, and reboot to a standard DOS environment.
   If you have a NTFS only system and can not boot DOS contact Summagraphics
   Technical Suppport.

3) Copy the expanded CSRSRV.DLL to the \SYSTEM32 directory of NT.
   For example:

                COPY C:\CSRSRV.DLL C:\WINNT35\SYSTEM32\CSRSRV.DLL

   You'll be prompted as to whether or not you wish to replace the file.
   Hit Y to replace.

4) Reboot the system into NT.



NOTES ON ADMINISTRATOR PRIVILEGES
---------------------------------
Problem description:  Changes in Control Panel are not saved unless you
are logged into a NT account with Administrator privileges.

We are currently working with the InstallShield people on a real fix,
until then here is a manual fix:

1) Log into a NT account with Administrator privileges.

2) Run the advanced version of the NT Registry Editor from the following
   directory:

               \NT\SYSTEM32\REGEDT32.EXE

3) Select/highlight the following key/folder.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Service\tabport\Parameters

4) Select Permissions from the Security pull down menu.

5) Select/highlight "Everyone".

6) Change the Type of Access: to "Full Control" from the popup menu in the
   lower right corner of the dialog box.

7) Hit OK, Exit and your done.

mode.  Using this tablet in Relative mode will produce erratic results.

with the SummaSketch 6x9LC, see notes above.


********************************** 3 ****************************************
************************** APPLICATION NOTES ********************************
*****************************************************************************

AUTOCAD NOTES
-------------
AutoCAD release 13c2a or greater is required.

WHIP Video Driver: There is a known problem with the ACAD WHIP video
driver and the Wintab driver on NT 3.50.  Upgrade to NT 3.51 to use
the WHIP driver with Wintab.

BUTTON ASSIGNMENTS: When using cursor buttons in the autocad screen menu
area the buttons act as the defined mouse buttons. If you move out of the
screen menu area into the template area the cursor buttons use the button
definitions in the ACAD.MNU file.  If you want to use the ACAD.MNU
definitions in the screen menu area set the Summagraphics Control Panel
button definitions to none.


ADOBE PHOTOSHOP AND PRESSURE SENSITIVITY UNDER NT
-------------------------------------------------
Adobe Photoshop release 3.04 supports the WINTAB32 standard under NT and
properly recognizes and uses pressure data from the Summasoft NT drivers.
