2.If you have just made a change in your system configuration, your computer may take a few minutes to complete its power-on diagnostics. The first time you turn on your computer after making such a change, it can take several minutes to finish its self test, depending on what you changed. If the computer does not display the operating system prompt after five minutes, turn off the computer, wait 20 seconds, and try again. If that doesn’t work, turn off the computer, insert your main operating system diskette or Reference diskette in drive A and turn on the computer.

If it still does not boot, contact your Authorized Epson Servicer.
