Logitech Windows NT mouse drivers
		    =================================

 These Windows NT mouse drivers are still under development and have not 
 been extensively tested. These drivers are provided to help Windows NT Beta 
 testers utilize their Logitech mice under the October 1992 release of 
 Windows NT.

 These NT mouse drivers are provided "as is". Logitech does not warrant that 
 these drivers will meet users requirements, or that they will function in 
 combination with other software or hardware which may be selected for use by 
 users. LOGITECH MAKES NO WARRANTIES OR REPRESENTATION ABOUT COMPATIBILITY OF
 THESE DRIVERS WITH ANY PC-COMPATIBLE PLATFORM. IN NO EVENT SHALL LOGITECH BE 
 LIABLE FOR LOST PROFIT, LOST DATA, LOST OR DAMAGED PROGRAMS, OR ANY 
 CONSEQUENTIAL OR INCIDENTAL DAMAGES ARISING OUT OF THE USE OF THESE DRIVERS.

 How To Install:
 ---------------
 
 Logitech Windows NT mouse drivers are provided in a self-extracting .EXE
 file format. After you have downloaded LMOUSENT.EXE, proceed with the 
 following steps:

 1] Copy LMOUSENT.EXE to a temporary directory on the hard drive (i.e., \TEMP)
 2] Log onto this temporary directory by typing:

 CD \TEMP.............where TEMP is the directory in which LMOUSENT.EXE exists

 3] Uncompress LMOUSENT.EXE by typing:

 LMOUSENT.............then press Enter
 
 4] Start Windows NT
 5] Select the RUN command from the FILE menu and type in:

 C:\TEMP\INSTALL......then press Enter

 6] Once the installation is completed, select Shutdown from the File menu
 in order to restart NT and cause the new changes to take effect.
 
 Note: The current mouse drivers are backed up to the same file names with the 
       .BAK file extension.

 Feedback:
 ---------
 
 These files can be obtained from either:

 Your feedback and comments are important to us. Make sure that you leave any
 comments regarding problems encountered using these drivers on one of the
 above electronic media, preferably Logitech forum on CompuServe.

 Technical Information:
 -----------------------

 This LMOUSENT.EXE contains two drivers:

 1) BUSMOUSE.SYS which supports all of Logitech BUS mice. The bus board 
 address and interrupt jumper should be properly set. The Hardware Interrupts 
 (IRQs) supported are 2,3,4 & 5 and the I/O address is 0x023C

 2) SERMOUSE.SYS which supports all of Logitech Serial mice. All Serial mice 
 previously supported (before installing these drivers) by the old 
 SERMOUSE.SYS driver are also supported.

 Compatibility:
 --------------

 These drivers are compatible with the Windows NT SDK October release. These
 drivers will NOT work under future Windows NT releases due to changes in the
 pointing device data report format. At the time of future releases of Windows
 NT, Logitech will have new mouse drivers.

 Advanced features like orientation for the Logitech TrackMan line of 
 Pointing Devices is not currently supported.

 Troubleshooting:
 ----------------

 - If the mouse doesn't respond, make sure it works correctly under DOS.
   
 - These drivers are needed if you previously experienced a "jumping" cursor 
   on the screen under NT. 

 - If you are using a Serial mouse under DOS, you may have to turn off your 
   computer before restarting Windows NT or unplug the mouse to power it down,
   otherwise the mouse may not be recognized under NT. An alternative solution
   might be to reload the Logitech DOS mouse driver with the parameter "1200" 
   to reset the mouse to 1200 baud. This can be done by loading the mouse 
   driver under DOS by typing the following command:
		
	       MOUSE 1200
 
*  This is currently due to a limitation of NtDetect (part of Windows NT).
  
 - The installation program makes a few assumptions about the current values
   in the registry. The changes to the registry are (use regedit if you need
   to get back to the default):

   Path: Registry\machine\system\currentcontrolset\service

   Original     Tag                     New Tag
   Null.sys     0x01                    0x01
   Beep.sys     0x02                    0x02
   DzPort.sys   0x03                    0x03
   I8042Prt.sys 0x04                    0x04
   Inport.sys   0x05                    0x05
   BusMouse.sys ----                    0x06            
   SerMouse.sys 0x06                    0x07 
   MouClass.sys 0x07                    0x08 
   Mouse.sys    0x08                    0x09 
   KbdClass.sys 0x09                    0x0A 
   Keyborad.sys 0x0A                    0x0B 
   SqikbMou.sys 0x0B                    0x0C 

   The new driver entries will contain by default the following fields (look
   at the INSTALL.INI file for more information):

   BusMouse     Type = 0x01
		Start = 0x01
		Group = Base
		ErrorControl = 0x01
		Tag = 0x06

    BusMouse\Parameters
		MouseDataQueueSize = 0x64
		NumberOfButtons = 0x03
		SampleRate = 0x28
		PointerDeviceBaseName = PointerPort
