For both IOD tests and PCI 0 and PCI 1 tests, trace and failure status is sent to the
OCP. If any of these tests fail, a warning is sent to the SRM console device after the
console prompt (or AlphaBIOS pop-up box). The LEDs on the system bus to PCI
bus bridge module are controlled by the diagnostics. If a LED is off, a failure
occurred.
