If the mouse driver is installed, but the mouse does not work, the
problem may be due to one of the following:
- A software conflict
- A hardware conflict
- A faulty mouse
Troubleshoot mouse problems as follows:
- To rule out a software conflict, boot from a "vanilla" MS-DOS (that
is, no AUTOEXEC.BAT or CONFIG.SYS files) and manually install the
mouse driver from the Mouse Setup disk by typing "MOUSE".
- If you have a serial mouse, make sure that your serial ports are
- Verify that the mouse driver is installed on the correct device.
Problems can occur if the mouse driver is installed on a device
other than the mouse port; for example, a noisy bus can cause the
driver to install for a bus mouse or a device such as a modem can
cause the driver to think a serial mouse is being used.
If you suspect the driver is not installing on the correct port,
use the mouse switches to direct the driver to the specific port.
For example, if your mouse is on COM2, load the mouse driver with
the following command:
MOUSE /C2 <- install driver on COM2
- If you have a bus mouse, check the jumper settings for a possible
interrupt conflict, an I/O address conflict, or expansion slot
- If the problems continue, test the mouse on another machine to
determine if you have a faulty mouse.
