SETUP function keys (continued)
Whenever you are in SETUP, the bottom of the screen lists the
keys you can press to perform specific functions.
The System Setup Option
When you select this option, you see the System Setup screen.
From this screen, you can set the system time and date, define
your video display type, check system memory, and define the
diskette drives.
Setting the Time and Date
The real-time clock in your computer continuously tracks the
date and time-even when the computer is turned off. Once
you set the System Time and System Date options, you
should not need to change them, unless you adjust the time for
daylight savings or a different time zone. (The computer
automatically changes the date for leap years.)
