NOMOUSE.DRV Is Required when No Mouse Is Installed

ID: Q81523

The information in this article applies to:

Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11

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

MORE INFORMATION

Double-click the Windows Setup icon from the Main program group.

From the Options menu, choose Change System Settings.
