Introduction
This chapter contains a selection of alarms, error messages and troubleshooting information.
Self-test POST
During booting, the BIOS first performs a Power On Self-Test or POST. This checks to
ensure that certain device components are functioning properly. The boot sequence is
interrupted immediately if critical errors occur.
If the POST does not find an error, the BIOS initializes and tests further components. The
graphics are already initialized in this phase of booting. Any error messages that occur are
displayed on the screen.
Error diagnostics
The following describes the error message from the system BIOS.
