SROM Errors Reported
The SROM reports machine checks, pending interrupt/exception errors, and
errors related to corruption of FEPROM 0. If SROM errors are fatal, the
particular CPU will hang and only the CPU self-test pass LEDs and/or the LEDs
on the system motherboard will indicate the failure. The CPU self-test pass
LED is not visible but the IOD0 and IOD1 pass LEDs are.
