Table 2. Mixed Processor Configurations
Error Severity System Action
Processor family not
identical
Halt The BIOS detects the error condition and responds as follows:
– Logs the error into the system event log (SEL).
– Alerts the Integrated BMC about the configuration error.
– Does not disable the processor.
– Displays “0194: Processor 0x family mismatch detected” message in
the Error Manager.
– Halts the system and will not boot until the fault condition is
remedied.
Processor stepping
mismatch
Pause The BIOS detects the stepping difference and responds as follows:
– Checks to see whether the steppings are compatible – typically +/-
one stepping.
– If so, no error is generated (this is not an error condition).
– Continues to boot the system successfully.
Otherwise, this is a stepping mismatch error, and the BIOS responds as
follows:
– Displays “0193: Processor 0x stepping mismatch” message in the
Error Manager and logs it into the SEL.
– Takes Minor Error action and continues to boot the system.
Processor cache not
identical
Halt The BIOS detects the error condition and responds as follows:
– Logs the error into the SEL.
– Alerts the Integrated BMC about the configuration error.
– Does not disable the processor.
– Displays “0192: Processor 0x cache size mismatch detected”
message in the Error Manager.
– Halts the system and will not boot until the fault condition is
remedied.
Processor frequency
(speed) not identical
Halt The BIOS detects the error condition and responds as follows:
– Adjusts all processor frequencies to the highest common frequency.
– No error is generated – this is not an error condition.
– Continues to boot the system successfully.
If the frequencies for all processors cannot be adjusted to be the same,
then the BIOS:
– Logs the error into the SEL.
– Displays “0197: Processor 0x family is not supported” message in the
Error Manager.
– Halts the system and will not boot until the fault condition is
remedied.
