Starting your computer
What you see and hear when you turn on your computer depends on the settings
in the Start Options menu of the Configuration/Setup Utility program. For more
information, see “Chapter 4. Using the Configuration/Setup Utility program,” on
page 27.
If any errors are detected during POST, error messages are displayed. If a power-

both power-on and administrator passwords, you can type either password at the
password prompt. When you type your password at the prompt and press Enter,
the first screen of your operating system or application program is displayed.
