Basic Pre-boot Diagnostics
The first diagnostic (called basic pre-boot diagnostics) is run to check the
presence of the processor(s) or terminators, VRMs, power supply, CPU
Board PLL and memory.
The pre-boot diagnostic tests are run in order of priority with respect to
their importance to computer functions.
The first detected error displays a message on the LCD status panel. If this
happens, one of the following screens could appear.
The following diagram shows how the Pre-boot Diagnostics works when it
encounters an error.
