PRWIN9107002: Demo Engine Setup Bad for Serial Logitech Mouse

ID Number: Q74392

Summary:

PROBLEM ID: WIN9107002

SYMPTOMS

When the Windows 3.0 demo engine Setup program is run on a machine

with a Logitech serial mouse, the mouse is not detected, and the

demo engine is configured as if the machine had no mouse.

CAUSE

The Setup program for the demo engine does not always recognize

Logitech serial mice.

RESOLUTION

If the Setup program does not detect a mouse, it will install the

default driver specified in ENABLER.INF. ENABLER.INF can be

modified to specify the Logitech serial mouse driver (LMOUSE.DRV),

instead of the "no mouse" driver (NOMOUSE.DRV) as the default

driver. If this change is made, and the demo engine is set up on a

machine that does not have a mouse, the Logitech serial mouse

driver will be installed. This will cause an unmovable cursor to be

displayed in the middle of the screen. In all other cases, the

correct mouse driver will be installed.

To make the serial Logitech mouse driver the default driver, the

following two changes should be made to ENABLER.INF:

1. Add "1:lmouse.drv" to the end of the [win.sys] section, which

lists the system files to be copied. After the modification the

section should resemble the following:

[win.sys]

1:KRNL286.EXE, "Windows System files"

1:DOSX.EXE

1:WINOLDAP.MOD

1:WINOA286.MOD

1:WIN87EM.DLL

1:lmouse.drv ; added

2. In the [machine] section, replace "nomouse" with "lmouse". After

the modification, the section should resemble the following:

[machine]

"MS-DOS or PC-DOS System","1" ;DO NOT CHANGE THIS NUMBER!!

Microsoft has confirmed this to be a problem in the Windows Demo

Engine Setup Program version 3.00. We are researching this problem

and will post new information here as it becomes available.
