DEC PC 320SX with Logitech Mouse May Not Enter Enhanced Mode

• Microsoft Windows versions 3.1, 3.11

SYMPTOMS

When you try to run Windows version 3.1 in enhanced mode on a DEC PC 320SX with an external Logitech Mouse, Windows may return to the MS-DOS command prompt.

CAUSE

This is caused by a conflict with the built-in keyboard mouse device.

RESOLUTION

To resolve the problem, press CTRL+ALT+SHIFT+DEL to enter the CMOS setup and disable the DEC PC 320SX keyboard mouse.

MORE INFORMATION

The DEC PC 320SX is a laptop with a built-in cursor controller that emulates a Microsoft Mouse. If Logitech drivers are used for a Logitech Mouse, the cursor controller will prevent the system from entering enhanced mode due to the Logitech driver.

If the Microsoft or IBM PS/2 Mouse driver is selected, Windows will work in enhanced mode, but the mouse will not function. Both Windows and the mouse will function correctly in standard mode.

To resolve this problem and allow use of a Logitech or any other type of mouse, press CTRL+ALT+SHIFT+DEL to enter the CMOS setup and disable the keyboard cursor controller that emulates a Microsoft Mouse.
