At the conclusion of testing, the OpenBoot PROM automatically configures the
system, omitting any devices that have failed diagnostics. After POST ends, the

Note – POST does not test drives or SBus cards. To test these devices, run OpenBoot
PROM diagnostics before the system has booted. Appendix E, "Selected On-Board
