The Public Utilities Emergency Disk Builder is provided in case your Macintosh will not start up from one of the two enclosed Emergency Disks. Some newer model Macintoshes require a special “enabler” file in their System Folder to start up. You should first try starting up your Mac from the enclosed Emergency Disks. If your Mac starts up, you don’t need to build an Emergency Disk, the enclosed Emergency Disk will work correctly. (Don’t be afraid to try starting up your Mac with the wrong System software, you won't hurt your Macintosh.)
If your Mac will not start up from either of the enclosed Emergency Disks, you need to run the Emergency Disk Builder from your hard disk to create a new Emergency Disk. The new Emergency Disk will contain a special enabler file (provided by Apple) which your Macintosh needs to start up. Rather than releasing a new version of the System software for each new Macintosh, starting with System 7.1 Apple includes an enabler file to support each new Macintosh. Each enabler only works with certain Macintosh models, this means if you have two different model Macintoshes you may need to build two different Emergency Disks. You can check this either by trying to start up from the Emergency Disk or by checking your Mac’s compatibility on the list below.
To make an Emergency Disk, launch the “Emergency Disk Builder” application from your hard disk. Click on the “Create Disk” button and follow the directions. Each Emergency Disk requires a blank high density (1.4 M) floppy disk.
