IMPORTANT Certain system extensions or application programs that were originally on your hard disk may not be installed with the Installer program. If you notice that a certain extension or program was not installed, you may need to install it separately. You can find some of these additional extensions and programs in the disk images that come on your computer’s hard disk. (You can make installer disks from the disk images with the Floppy Disk Maker application program.)
