• Major: If the Post Error Pause setup option is enabled, the system goes directly to
the error manager. Otherwise, the system continues to boot and no prompt is given
for the error. The error is logged to the error manager.
Table 4. Mixed Processor Configurations
Error Severity System Action
Processor family not identical Fatal The BIOS detects the error condition and responds as follows:
• Logs the error into the system event log (SEL).
• Alerts the Integrated BMC of the configuration error
with an IPMI command.
• Does not disable the processor.
• Displays “0194: Processor family mismatch detected”
message in the error manager.
• Halts the system.
Processor cache not
identical
Fatal The BIOS detects the error condition and responds as follows:
• Logs the error into the SEL.
• Alerts the Integrated BMC of the configuration error
with an IPMI command.
• Does not disable the processor.
• Displays “0192: Cache size mismatch detected”
message in the error manager.
• Halts the system.
Processor frequency (speed)
not identical
Major The BIOS detects the error condition and responds as follows:
• Adjusts all processor frequencies to the lowest
common denominator.
• 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 speeds mismatched”
message in the error manager.
• Halts the system.
Processor microcode
missing
Minor The BIOS detects the error condition and responds as follows:
• Logs the error into the SEL.
• Does not disable the processor.
• Displays “816x: Processor 0x unable to apply
microcode update” message in the error manager.
• The system continues to boot in a degraded state,
regardless of the setting of POST Error Pause in the
Setup.
