Title: Keyboard Lockup During Installation Bug
Entry Number: 1480
Last Modified: <<Date June 17, 1997>>

Q: When I try to install NEXTSTEP Release 3.2 for Intel Processors onto my computer, the keyboard locks up, and I am unable to complete the installation.

What's going on?  How do I get the installation to complete?  Is the computer now unusable?

A: There is a known bug which may lock up your keyboard during installation onto systems which do not have integrated PS/2 mouse support. The problem is in the PS/2 mouse driver, and removing the PS/2 mouse driver from your default configuration will work around the problem.

The following entry will prevent the PS/2 mouse driver from being automatically loaded. By default, NEXTSTEP loads the following drivers during installation and when booting config=Default: PS2Keyboard, PS2Mouse, Adaptec1542B, DPT2012, IDE, and Floppy.  To remove the PS2Mouse driver from this list, type the following at the boot: prompt:

"Boot Drivers"="PS2Keyboard Adaptec1542B DPT2012 IDE Floppy"

While configuring during the installation process, be certain to remove the instance of the PS2Mouse driver which is automatically added by Configure.
