Apple Macintosh PowerBook 150 - Manual (Page 10)

The Apple HD SC Setup and Internal HD Format utilities
The Apple HD SC Setup utility program that comes with many Macintosh
and PowerBook computers is not designed for use with the internal hard disk
of the PowerBook 150. Instead, your Utilities disk includes a utility program
called Internal HD Format, which was designed to work specifically with the
hard disk in your PowerBook 150 computer.
If you ever need to initialize your internal hard disk, refer to “Disk Drives and
Disks” in Chapter 9 of this Getting Started book for instructions on using the
Internal HD Format utility. Please disregard the instructions in “Initializing
a Hard Disk” on pages 10–11 of the Macintosh Reference book.
You cannot use the Internal HD Format program to test a hard disk.
Therefore, please disregard the instructions in “Testing a Hard Disk” on
page 21 of the Macintosh Reference book.
Using a RAM disk
The instructions for setting up and using a RAM disk on pages 71–72 of the
Macintosh Reference book are slightly incorrect for the PowerBook 150. Please
refer instead to the instructions on pages 85–87 of this Getting Started book.
Using the Chooser to select a printer
The PowerBook 150 has only a printer port, not an external modem port. On
page 76 of the Macintosh Reference book, please disregard the instruction to
select a port; your printer port will be selected automatically when you open
the Chooser.
