HAT-processor Windows NT driver
===============================

This driver only works in Windows NT 4.0 server and workstation.
Do not install it in any other Windows version.
Note! This driver does not work in Windows 2000.

This driver version adds support for Softex PC Card system software.

1. Make sure you have logged in as administrator.
   To be able to complete the installation succesfully
   some changes must be made in the registry which
   require administrator access rights.

2. Copy the "Hatproc.sys" file to your hard disk into
   the directory C:\Winnt\System32\drivers\

3. Open "Command Prompt"
 - use "cd" command to choose the directory where HAT.exe is located
   for example: "cd C:\Programs\HAT"
 - type command "HAT /instnt"
 - type command "HAT /associate"

   For these commands to work you must have HAT.exe version 4.1
   or later.

4. Restart your computer.

5. Run HAT.exe application
   If no error messages come up now and you can run HAT.exe,
   the installation is complete.

6. Configuring the HAT-processor driver.
   If an error message comes up when starting HAT.exe, you
   can click "Configure.." button to manually configure
   the HAT-processor driver.

   You can also bring up the configuration dialog on
   command line: "HAT /confignt"

   Note! HAT 4.2a05 or later is required to configure the driver.

   In the configuration dialog you should select the correct
   PC Card interface. If your computer has Softex PC Card
   support installed, select Softex.

   After changing the settings, you must reboot.
