1-28 Using Your Computer
Power on (boot) your computer as follows.
1. Check that the power cables from the monitor and
system unit are connected to a wall outlet or surge
protector.
2. If you are booting from the hard disk, make sure that
the diskette drive is empty.
To boot from the diskette drive, be sure that you have a
diskette in drive A containing operating system files. See
your operating system documentation for information
about creating system diskettes.
NOTE
The system looks for the drive containing
operating system files. If you have a diskette with
MS-DOS or another operating system's files in drive
A, the system boots from the diskette drive. If you
do not have a diskette in drive A, the system boots
from the hard disk.
A diskette without operating system files in drive A
prevents a system boot and displays the error mes-
sage, “non system disk installed in drive A.”
Booting from a diskette can be disabled for virus
protection in the Setup utility (see Chapter 2).
3. Turn on the power to the monitor.
4. Turn on power to the system unit by pressing the power
button on the front panel.
At power-on, the system unit's power lamp lights (green)
and the power-on screen appears. If necessary, adjust the
contrast and brightness controls on the monitor.
