Resetting the Computer
Occasionally, you may want to clear the computer’s memory
without turning it off. You can do this by resetting the
computer.
For example, if an error occurs and the computer does not
respond to your keyboard entries, you can reset it to reload
your operating system and try again. However, resetting erases
any data in memory that you have not saved; so reset only if
necessary.
Caution
Do not reset the computer to exit a program. Some programs
classify and store new data when you exit them. If you reset
the computer without properly exiting a program, you may
lose data.
When you reset the computer, the operating system must be
either on the hard disk or on a diskette in drive A; so if you do
not have a hard disk, insert the operating system diskette in
drive A. If you are using DOS, you can hold down Ctrl and Alt
and press Del.
If you
set the Disk drive boot sequence option in SETUP
to
C: only (see Chapter 2), the operating system must be on
the hard disk when you reset the computer. If you selected
A:
then C: or C: then A:, the operating system must be either
on the hard disk or on a diskette in drive A. If you do not have
a hard disk, insert a bootable diskette (one that contains the
necessary portions of the operating system) in drive A. If you
are using MS-DOS, press Ctrl Alt and Del
to reset the system.
You can also press the RESETbutton located on the front panel
of your computer. The screen displays nothing for a moment
and then the computer reloads the operating system.
