1.3.2 Start-Up Sequence
When the main power switch is turned on, the CPU on the main controller PCB executes
the self-diagnosis program stored in the boot ROM.
The self-diagnosis program is designed to check the condition of the SDRAM and hard
disk, and indicates any error it detects on the control panel in the form of an error code.
