SUMMARY
When Express Setup is used to upgrade Microsoft Windows 3.0a to Microsoft
Windows 3.1 or 3.11 on a system with a Logitech mouse, the LMOUSE.DRV file
and the virtual driver file LVMD.386 are not installed.
This article describes the procedure for installing these drivers.
MORE INFORMATION
To install these drivers:
- At the MS-DOS command prompt, copy EXPAND.EXE from Disk 3 of the
Windows setup disks to the root directory on drive C. For example,
if disk 3 is in drive A, you would type the following and press
ENTER:
copy a:expand.exe c:\
- Delete the LMOUSE.DRV file in the Windows\SYSTEM subdirectory. To do
this, use the MS-DOS CD command to change to the Windows\SYSTEM
subdirectory, then issue the MS-DOS DEL command. The following is an
example (press ENTER at the end of each line):
cd\windows\system
del lmouse.drv
- If you are using 1.2 MB or 1.44 MB Windows setup disks, insert Disk
2. If you are using 720K disks insert Disk 4.
- Type the following commands (press ENTER at the end of each line):
expand a:lmouse.dr_ c:\windows\system\lmouse.drv
expand a:lvmd.38_ c:\windows\system\lvmd.386
- Edit the SYSTEM.INI file with a standard ASCII text editor (such as
Notepad or the Microsoft MS-DOS version 5.0 Editor) and make sure
the following two lines exist under the correct section header.
The following line should already exist:
[boot]
MOUSE.DRV=LMOUSE.DRV
The following line replaces MOUSE=*VMD:
[386Enh]
MOUSE=LVMD.386
NOTE: If you run Setup from inside of Windows to switch from any available
mouse selection and switch to Logitech Mouse, then LMOUSE.DRV and LVMD.386
are copied to your system from the Windows disks. LMOUSE.COM is not copied.
LMOUSE.COM is necessary for mouse support for non-Windows-based
applications and should be loaded before starting Windows.
Use the following command line to expand LMOUSE.COM from the Windows
disks:
expand a:\lmouse.co_ c:\windows\lmouse.com
