Intel® SRMK2 Internet Server Technical Product Specification 87
9.3.3 Memory Bus Error
The CNB30LE generates SERR# on single and multiple -bit errors. The following register bits
control and log the errors. The following tables show the action taken by each error handler, and
control bits associated with the error.
Table 59: Error handler action on memory bus error
Handler Action
BIOS NMI Emulation or Disable NMI
OS NMI Log the error and shut down the system
BIOS SMI Log the error
Note: The SMI handler might emulate processor bus fatal errors (only),
and pass control to the BIOS NMI handler.
Table 60: Memory bus error control bits
Location Function Bit Description Value
CNB30LE 46h ERRCMD 2 Enable SERR# on Uncorrectable ECC Error 1-enabled, 0-disabled
1 Enable SALERT on ECC Correctable Error 1-enabled, 0-disabled
CNB30LE 47h ERRSTS 2 DRAM Uncorrectable Error 1 = error, 0 = OK
1 DRAM Correctable Error 1 = error, 0 = OK
CNB30LE E8h ECCSYN 7::0 ECC syndrome bits varies
9.3.4 System Limit Error
The SRMK2 Heceta 3 ASIC monitors system operational limits. It manages the A/D converter,
defines voltage and temperature limits, and defines chassis intrusion. Any sensor values outside of
specified limits are fully handled by the BIOS and OS software. The BIOS response to any
critical Heceta 3 error is to log the error, display an error condition, and shut down the system.
9.3.5 Processor Failure
The BIOS detects BIST failure and watchdog timer reset events.
9.4 Error Messages and Error Codes
The following tables show the beep codes and error messages for AMIBIOS.
Table 61: Beep codes
Beeps Error message Description
1 Refresh Failure The memory refresh circuitry is faulty.
2 Parity Error
A parity error in the base memory (the first 64 KB block) of
memory.
3
Base 64 KB Memory
Failure
A memory failure in first 64 KB.
4 Timer Not Operational
A memory failure in the first 64 KB of memory, or Timer 1 is not
functioning.
5 Processor Error The CPU generated an error.
6
8042 - Gate A20
Failure
Cannot switch to protected mode.
7
Processor Exception
Interrupt Error
The CPU on the CPU Card generated an exception interrupt.
