2.4 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 bus to PCI bus bridge module will indicate the failure.
