    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.
