SUMMARY
When a mouse driver is removed from Microsoft Windows, Windows requires
that the NOMOUSE.DRV driver be installed. This driver tells Windows that
a mouse is not present. This is necessary because Windows requires a driver
to be associated with the "Mouse.drv=" line in the [boot] section of the
SYSTEM.INI file. During startup, Windows takes the following actions
depending on what it finds in the "Mouse.drv=" line:
- If the Mouse.drv= line does not have an entry after the equal (=) sign,
Windows exits to an MS-DOS command prompt.
- If the Mouse.drv= line is missing from the SYSTEM.INI file, Windows
looks in the Windows and system directories and the path. If there is a
MOUSE.DRV file there, then it uses it, regardless of file date or size.
- If there is no MOUSE.DRV file, then Windows exits to an MS-DOS command
prompt.
Windows does not search for the following mouse drivers:
NOMOUSE.DRV
LMOUSE.DRV
MSMOUSE.DRV
MSMOUSE2.DRV
