Table 2. Mixed Processor Configurations

Severity
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.
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.
–
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.
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.
