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

off.

Hard Disk Control

system on it, the system will go to Drive 4 first, and automatically
load the operating system. You can then begin using your system.
