Intel® Server Board S2600CP Functional Architecture Intel® Server Board S2600CP and Server System P4000CP TPS Error Processor Intel® QuickPath Interconnect link frequencies not identical Severity Fatal System Action The BIOS detects the QPI link frequencies and responds as follows:  Adjusts all QPI interconnect link frequencies to highest common frequency.  No error is generated - this is not an error condition.  Continues to boot the system successfully. Processor microcode update Minor missing Processor microcode update Major failed If the link frequencies for all QPI links cannot be adjusted to be the same, then this is an error, and the BIOS responds as follows:  Logs the POST Error Code into the SEL.  Alerts the BMC to set the System Status LED to steady Amber.  Displays "0195: Processor Intel(R) QPI link frequencies unable to synchronize" message in the Error Manager.  Does not disable the processor. Takes Fatal Error action (see above) and will not boot until the fault condition is remedied. The BIOS detects the error condition and responds as follows:  Logs the POST Error Code into the SEL.  Displays "818x: Processor 0x microcode update not found" message in the Error Manager or on the screen.  The system continues to boot in a degraded state, regardless of the setting of POST Error Pause in the Setup. The BIOS detects the error condition and responds as follows:  Logs the POST Error Code into the SEL.  Displays "816x: Processor 0x unable to apply microcode update" message in the Error Manager or on the screen.  Takes Major Error action. The system may continue to boot in a degraded state, depending on the setting of POST Error Pause in Setup, or may halt with the POST Error Code in the Error Manager waiting for operator intervention. 30 Revision 1.2 Intel order number G26942-003
