Note: The current mouse drivers are backed up to the same file names with the
.BAK file extension.
These files can be obtained from either:
Logitech BBS at 510-795-0408 or
Logitech forum on CompuServe (Go Logitech).
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

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.

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.
- 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:
* 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):
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
MouseDataQueueSize = 0x64
NumberOfButtons = 0x03
SampleRate = 0x28
PointerDeviceBaseName = PointerPort
