    This article contains the procedure for performing a clean installation of System 7.5.5.

DISCUSSION

    Step 1: Find out which version of system software you should install.

    The earliest version of system software you should install on your Macintosh computer is System 7.5.5. Apple has tested this version for Year 2000 compliance on Macintosh computers back to and including the Macintosh Plus. It is available for free download from Apple's Web site. See step two for more information on how to get it.

    System 7.5.5 requires at least 4 MB of memory and up to 21 MB of hard disk space. Make sure your computer meets these minimum requirements before proceeding.

    Your Macintosh computer may be able to use a later version of system software if it came with a later version, or if you purchased an upgrade. For more information on performing a clean installation of versions later than 7.5.5, please see the links at the end of this article.


    Step 2: Get the system software you need.

    Find the system software CD or floppy disk set that came with your computer. If it includes System 7.5.3, you only need to get System 7.5.5 Update.

    Download

    System 7.5.5 can be downloaded from the Apple Software Updates Web site at http://www.apple.com/swupdates in a two-step process. First, you must download System 7.5.3, then System 7.5.5 Update.

    Order a CD or floppy disk set

    If you live in Canada or the United States, call 1 (888) 273-3594 to order the Apple Legacy 2000 CD, or the System 7.5.3 and System 7.5.5 Update disk set. Either is available for 35.00 USD plus shipping and applicable taxes.


    Step 3: Start up the computer from the Disk Tools disk, or system software CD.

    If your computer only has a floppy drive, start up the computer using a Disk Tools disk. If your computer has a CD-ROM drive, start up the computer using your system software CD.

    Important: If you don't have a Disk Tools disk, order the Apple Legacy 2000 CD or System 7.5.3 and System 7.5.5 Update disk set described in Step 2 before you proceed.


    Step 4: Run the Disk First Aid program to repair any errors.

    After you have started up the computer from the Disk Tools disk or the system software CD, open the Disk First Aid program. Select the hard disk you want to check by clicking on its icon in the Disk First Aid window. Click the Verify button. Disk First Aid checks your disk for any errors. If Disk First Aid reports any errors, click the Repair button to repair them. Quit the Disk First Aid application.


    Step 5: Update the hard drive driver software.

    Find the appropriate hard drive utility for your computer on the Disk Tools disk or system software disc. Use Apple HD SC Setup with Macintosh computers that have a Motorola 680x0 family microprocessor and a SCSI hard drive. The following Macintosh computers have IDE hard drives and require that you use the Drive Setup application:
    • Macintosh LC 580
    • Macintosh LC 630
    • Macintosh LC 630 DOS
    • Macintosh Quadra 630 series
    • Macintosh Performa 580 series
    • Macintosh Performa 630 and 640 series
    • PowerBook 190 series

    Apple HD SC Setup

    Open the Apple HD SC Setup application. Click the Drive button until the name of your hard disk you want to update appears. Click the Update button, then the Quit button.

    Drive Setup

    Open the Drive Setup application. Click the name of the hard disk you want to update. Choose Update Driver from the Functions menu. Quit the application.


    Step 6: Open the System 7.5.3 Installer application.

    If you downloaded System 7.5.3 to your computer's hard disk, find and open the file called System 7.5.3 01of19.smi, then open the Installer application.


    Step 7: Choose the Clean Installation option.

    When the Installer application has opened, click Continue. Make sure Easy Install is selected from the pop-up menu. Press the Command, Shift and K keys on the keyboard. Select Install New System Folder and click OK.

    Step 8: Click Clean Install to begin installation.

    Click Clean Install to being the installation. When it has finished, restart the computer. Find and open the Installer application for System 7.5.5 Update. Click Install.

    You have now finished installing a clean version of System 7.5.5 on your computer. The contents of your old System Folder are in a new folder named Previous System Folder.

    You may need to install additional software such as fonts, printer or other device drivers, and application support files. You should reinstall these items from their original disks.
