Epson 20 - Manual (Page 28)

(For more instructions on inserting, removing, and caring for
diskettes, see Chapter 4.)
You can turn on your computer with or without the MS-DOS
Startup diskette in the drive. With the Startup diskette in the top
drive (A) as it is now, the computer loads MS-DOS from that
drive. (If the drive is empty, the screen displays a message
prompting you to insert a system disk.)
4. To turn on the power, flip up the switch on the right side of the
computer, toward the back. The power light on the computer’s
front panel lights up. After a few seconds, the computer starts to
perform an internal self test.
If you cannot see the screen display clearly, use the controls on your
monitor to adjust the brightness and contrast until characters on the
screen are clear and bright. If the display is not stable, check your
monitor’s horizontal and vertical hold controls.
9 Loading MS-DOS
After the computer completes its self test, it displays how much
RAM (random access memory) is available and then loads MS-DOS,
the operating system. You see a prompt similar to this:
Current date is
Mon 02-13-89
Enter new date (mm-dd-yy)
You do not need to enter the date because you will soon be entering
the correct date and time when you run the Setup program in
Chapter 2. Press
Enter to accept the displayed date.
The screen displays the time prompt next:
Current time
is 16:21:15
Enter new time
Press Enter to accept the displayed time.
You then see the MS-DOS version number and copyright
information, followed by the MS-DOS command prompt:
