Basic Pre-boot Diagnostics

The first diagnostic (called basic pre-boot diagnostics) is run to check the
presence of the processor(s) or terminators, power supply, CPU Board PLL
and memory. Simply by having a power cord connected to the PC
Workstation activates the Basic Pre-boot Diagnostics.
The pre-boot diagnostic tests are run in order of priority with respect to
their importance to computer functions.
