CHAPTER 3: POWER-UP/POWER-DOWN
Always turn your Built-in Hard Disk System on and off exactly as
described in this chapter. Any change in the sequences might
damage the system and data.
You can use your Built-in Hard Disk System in two ways: under
hard disk control or under floppy diskette control. Because hard
disk operation is more efficient, you'll probably operate under hard
disk control most of the time.
Until you have prepared your hard disk (Chapter 4 or 5), you must
operate under floppy diskette control
Powering Up the System
1. Make sure all diskette drives are empty and all equipment is
off.
2. Turn on the System by pushing the power switch forward.

Secondary Hard Disk Drive if present, will be turned on
automatically. Allow 1 minute warm-up for the hard disk
drives,
3 Turn on any other peripheral equipment.
Hard Disk Control
After you have initialized your hard disk by storing your operating
system on
it, the system will go to Drive 4 first, and automatically
load the operating system. You can then begin using your system.
Floppy Diskette Control

the "white-out" of the video display. The message INSERT
DISKETTE is displayed to indicate that you are operating under
floppy diskette control.
