In Example 6-9, the primary processor indicates the version of the console
firmware.
The date and time stamp indicates the production date of the running console.
The SROM Rev information indicates the primary processor's serial ROM
version. The serial ROM contains the first level of console, diagnostic, and
bootstrap code. This code initializes the CPU programmable features and
diagnoses any faults detected along with the bootstrap path and bootstrapping
code execution out to the main console program (the second level of console,
diagnostic, and bootstrap code).
The console prompt indicates the number of the primary processor. In this
example used to describe the self-test results, there are four CPUs, two on the
module in node 0, and two on the module in node 1. Therefore, possible console
prompts that could appear are P00>>>, P01>>>, P02>>>, and P03>>>. In this
example, the second CPU on the first module was the first CPU to pass all three
rounds of testing, so it became the boot processor.
