Several third party companies produce utility type programs, some of these are:
* Norton Utilities
*╩Central Point Tools
* 5th Generation's 911
Most of these programs come with an emergency disk that allows you to startup your Macintosh computer from a floppy disk instead of the hard disk. In the fall of 1992, Apple started using System Enablers with all new Macintosh computers. The emergency disks provided by most utility type programs do not include the system enablers you need to use the emergency disks. You need to either install the proper System Enabler from your system folder on your hard disk to the emergency disk, or follow the instructions provided with the utility application program.
a currently list of enablers is available in the document titled "System Enablers: Current Versions & Change History"
