Turning on and booting the computer
Turning the power on
To turn on the computer, press the lower, or white, P
The green POWER ON light should come on to show that the
system unit is powered. Remember that the monitor has its own
power control (see the monitor's User's Guide for details) and that it
may take a few moments to warm up. Do not touch the purple
button yet, that will be dealt with on the next page.
If nothing happens when the P
the system unit and monitor power cords are securely connected and
that the AC power supply is switched on. See also the chapter on
'Troubleshooting'.
Power-on self-test
Whenever the computer is turned on, the 'power-on self test' (POST)
routine checks the actual set-up of the computer against that
recorded in its internal configuration memory. During this time,
various messages are displayed. Further information on the
computer's Basic In/Out System (BIOS) and its setting up can be
found in Appendix C, 'System BIOS and set-up'.
The boot sequence
Provided that POST succeeds without any serious errors, the
computer attempts to find its operating system to start it going, that
is, it attempts to boot. By default, the computer will first look for a
floppy system disk, then for a bootable hard disk partition or area.
System disk
A system disk is a floppy disk bearing at least the rudiments of an
operating system. If the computer finds such a disk in the floppy or
A: drive, it boots from it. If it finds a non-system disk, the computer
will ask you to replace it.
Bootable hard disk
Most computers with a hard disk containing pre-installed software
arrive set up with a suitable 'boot partition'. The operating system
1/2
button is pressed, check that
OWER
button.
