Start-Up
Display
Every time you turn on your system, it runs start-up tests that
display important information.
These tests check the components in your system and fill a
status bar on the monitor screen (see Figure 5–1.) When the
status bar fills completely, and the system prompt (>>>) displays,
you know the tests were successful.
