 The diagnostics include i) primary CPU tests, ii) secondary CPU tests, and a memory test. The primary tests are performed before entering the console emulator; if a failure is detected, the processor goes into an infinite loop at the failing test. The secondary tests and memory test are run when a boot command is given from the console emulator.
