Follow these steps to turn on your system:

Turn your computer around so the front panel faces you.
Place your monitor, printer, and other devices in a
convenient arrangement.
If there is a protective card in the diskette drive, remove it
now.
Turn on the monitor, printer, and any other devices
connected to the computer.
Turn on the computer by pressing the power button on the
right side of the front panel.
The power indicator lights up, then the screen displays a
count of the system memory. The computer performs its
power-on diagnostics, which are a series of checks that
make sure everything is working correctly.
If necessary, use the controls on your monitor to adjust the
brightness and contrast until you can easily see the
characters on the screen.
If your system is configured to automatically load a program
(such as Microsoft Windows or a word processing
program), you see the first menu or screen display of that
program. If not, you may see the operating system prompt,
such as c:\>orA:\>.
If there is no operating system installed on your computer,
you see an error message. Ignore the message for now; once
you install the operating system, you will not see this
message.
Now follow the instructions in the next section to configure
your system using the SETUP program.
