Error Severity System Action
Processor frequency (speed)
not identical
Major The BIOS detects the error condition and responds as follows:
 Adjusts all processor frequencies to lowest common denominator
 Continues to boot the system successfully
If the frequencies for all processors cannot all 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
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 processor
 Displays “816x: Processor 0x unable to apply microcode update”
message in the error manager
 Pauses the system for user intervention
Processor FSB speeds 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 processor
 Displays “0195: Processor Front Side Bus speed mismatch
detected” message in the error manager
 Halts the system
3.2.10 Hyper-Threading Technology
Intel
®
Xeon
®
processors support Hyper-Threading Technology. The BIOS detects processors
that support this feature and enables the feature during POST. BIOS Setup provides an option
to enable or disable this feature. The default is enabled.
The BIOS creates additional entries in the ACPI MP tables to describe the virtual processors.
The SMBIOS Type 4 structure shows only the physical processors installed. It does not
describe the virtual processors.
Because some operating systems are not able to efficiently utilize the Hyper-Threading
Technology, the BIOS does not create entries in the Multi-Processor Specification tables to
describe the virtual processors.
3.2.11 Intel SpeedStep
®
Technology
Intel
®
Xeon
®
processors support the Geyserville feature of the Intel SpeedStep
®
technology.
This feature changes the processor operating ratio and voltage similar to the Thermal Monitor 1
(TM1) feature. Geyersville must be used in conjunction with the TM1. The BIOS implements the
Geyserville feature in conjunction with the TM1 feature.
3.2.12 Intel
®
Extended Memory 64 Technology (Intel
®
EM64T)
The system BIOS does the following:
