Apple 8600 appendix Performing a clean installation of system software

If the installation was not successful

If a message reports that installation was not successful, try installing again. (Follow the instructions on the screen.)

If, after reinstalling system software by doing a normal installation, you still experience problems with your computer, follow the steps in the next section for performing a “clean” installation of system software.

Performing a clean installation of system software

This section outlines what is commonly called a “clean” installation of system software. A clean installation allows you to discover which item in your System Folder is causing a problem. A clean installation creates a brand new System Folder and saves everything in your original System Folder in a different location. You can then follow the instructions in “Replacing Your Special Software” later in this section to reinstall system extensions, control panels, and other special software one at a time from the old System Folder to the new System Folder. This procedure allows you to determine which item in the old System Folder was the source of the problem.

Perform a clean installation if you can’t determine what is damaged in your System Folder (especially if you think any special software, such as control panels, system extensions, or custom utilities, may be causing the problems you’re experiencing). You should also perform a clean installation if you’re still having problems with your computer after you’ve reinstalled system software by performing a normal installation.

To perform a clean installation, follow these steps:

1Start up your computer from the CD-ROM disc that contains system software.

Do this by inserting the CD-ROM disc into the CD-ROM drive and holding down the C key while you restart the computer. For detailed steps, see “Starting Up From the System Software CD-ROM Disc” earlier in this chapter.
