3.2.6 Mixed Processor Cache Sizes
If the installed processors have mixed cache sizes, an error is reported to the BMC. The size of
all cache levels must match between all installed processors. See Table 4.
3.2.7 Microcode Update
If the system BIOS detects a processor for which a microcode update is not available, the BIOS
reports an error to the BMC. See Table 4.
IA-32 processors can correct specific errata by loading an Intel-supplied data block, known as a
microcode update. The BIOS stores the update in non-volatile memory and loads it into each
processor during POST. The BIOS allows a number of microcode updates to be stored in the
flash. This is limited by the amount of free space available.
3.2.8 Processor Cache
The BIOS enables all levels of processor cache as early as possible during POST. There are no
user options to modify the cache configuration, size, or policies. All detected cache sizes are
reported in the SMBIOS Type 7 structures. The largest and highest-level cache detected is
reported in BIOS Setup.
3.2.9 Mixed Processor Configuration
The following table describes mixed processor conditions and actions for all Intel
®
server boards
and systems that use the Intel
®
5000 Series Chipset. Errors fall into one of two categories:
 Halt: If the system can boot it will go directly to the error manager, regardless of the
“Post Error Pause” setup option.
 Pause: If “Post Error Pause” setup option is enabled, system will go directly to the error
manager. Otherwise the system will continue 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 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 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
