POST Indicators
POST (Power-On-Self-Test) indicators indicate tests that are being performed as the
system is preparing to load the operating system. The POST indicators are words
that display on the system console. Each time that the system starts a different step
in the POST, a POST indicator word appears on the console. Each word is an
indicator of the tests that are being performed.
The POST screen displays the following words:
