Apple LC 575 manual Using a modem, Starting up your computer from an external hard disk

Using a modem

If your computer came with a modem in the optional communications port, your Macintosh can communicate with other computers over standard telephone lines. (For instructions on how to use your modem, see the manual that came with your modem.)

You can have an internal modem installed in the additional communications port by an Apple-authorized dealer (if the port isn’t already in use). You can also purchase an external modem to connect to the modem port on the back of your computer.

Starting up your computer from an external hard disk

To start up your Macintosh from an external hard disk, the hard disk must contain a System Folder, and the System Folder must contain a System Enabler for your specific model of Macintosh. (A System Enabler file contains software necessary to start up a specific Macintosh model.)

If you are unable to start up your Macintosh from an external disk, the appropriate System Enabler file may be missing from that disk. Use the Installer program on the Install Me First disk that came with your computer to install system software on the external disk. If your computer came with a CD-ROM disc titled CD Install Me First, the software you need is on the CD-ROM disc.
