Important Information About the PowerBook VM Tuner

The PowerBook VM Tuner enhances system stability while using
virtual memory on your PowerBook 1400. During the
manufacturing process, the PowerBook VM Tuner file is
preloaded into the System Folder on your hard disk, but it
is not part of the "Install Mac OS" system software
installer. Therefore, if you reinstall the Mac OS 7.6 system
software, you may need to manually reinstall the PowerBook
VM Tuner file.

This document describes the PowerBook VM Tuner and when you
need to reinstall it.

What Is the PowerBook VM Tuner?

The PowerBook VM Tuner is a system extension that enhances
system stability on PowerBook 1400 models when running
memory intensive applications. It eliminates a problem with
moving the cursor during heavy memory use while virtual
memory is turned on.

Who Needs to Install the PowerBook VM Tuner?

The PowerBook VM Tuner was preloaded into the System Folder
during the manufacturing process, but if you reinstall the
Mac OS 7.6 system software, you may need to manually
reinstall the PowerBook VM Tuner file. If you do a "normal"
system software installation, you do not need to reinstall
the PowerBook VM Tuner. If you do a "clean" system software
installation, you will need to reinstall the PowerBook VM
Tuner.

A normal system software installation replaces changed
system files and adds new ones, but leaves alone other files
(such as the PowerBook VM Tuner). A clean system software
installation creates a new System Folder on your hard disk.
The old System Folder is renamed Previous System Folder.
Since your computer has a new System Folder, you must
reinstall the PowerBook VM Tuner in the new System Folder.

For more information about the differences between a normal
and a clean installation of system software, refer to the
Mac OS installation instructions in your PowerBook 1400
user's manual.

Installing the PowerBook VM Tuner

To install the PowerBook VM Tuner after performing a clean
installation of system software, follow these steps.

1. While holding down the Option key, drag the PowerBook VM
Tuner to the icon of the System Folder on your hard disk.

2. Click OK in the dialog box that appears.

3. Restart the computer.
