Epson EL 486UC - Manual (Page 27)

Whenever you are in the SETUP program, the bottom of the
screen lists the keys you can press to perform specific functions.
Displaying System Information
The SETUP program provides a system information screen that
lists the following:
Processor type
Coprocessor type (if you’ve installed a 486DX
microprocessor upgrade)
Reserved memory
BIOS version number
Addresses for video mode, serial ports, and printer ports
Option ROMs (if any ROM exists on your installed option
cards).
To see this information, press F2 from either of the SETUP
screens.
Setting the Date and Time
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 using
SETUP, you should not need to change them, unless you adjust
the time for daylight savings or other seasonal adjustments.
(The computer automatically changes the date for leap years.)
Use to move the cursor to the value you want to
change. Then press + or - until you see the value you want.
