PS/2 Appears to Hang When Exiting Windows 3.1 (82763)
The information in this article applies to:
- Microsoft Windows 3.1
- Microsoft Windows 3.11
This article was previously published under Q82763 SYMPTOMS
Some IBM PS/2 models may appear to stop responding (hang) when you exit
Windows version 3.1. The computer eventually restarts; however, it remains
frozen for up to a minute while the mouse port is reinitialized.
This problem is most severe on PS/2 models 56 and 57. It also occurs on
models 50z, 55sx, 70, 80, 90, and 95.
CAUSE
This behavior is caused by a problem in the IBM PS/2 mouse BIOS.
WORKAROUND
The problem can be corrected by adding the following line to the
[386Enh] section of SYSTEM.INI:
This prevents Windows from attempting to reinitialize the PS/2-style mouse
port prior to exiting to MS-DOS. This may cause problems when you run some
mouse-aware, MS-DOS-based applications after exiting Windows.
