5.3.3.3 POST Error Pause
In case of POST error(s), which occur during system boot-up, the BIOS will stop and wait for the
user to press an appropriate key before booting the OS or entering BIOS Setup.
5.4 Error Logging
5.4.1 Error Sources and Types
One of the major requirements of server management is to correctly and consistently handle
system errors. System errors can be categorized as follows:
• PCI bus
• Memory single- and multi-bit errors
• Sensors
• Processor internal errors, bus/address errors, thermal trip errors, temperatures and
voltages, and GTL voltage levels
• Errors detected during POST and logged as ‘POST errors’
Some system errors can be Enabled/Disabled individually (e.g., PCI Errors, FSB Errors and
Memory Errors) by the user in BIOS Setup.
Sensors are managed by the BMC. The BMC is capable of receiving event messages from
individual sensors and logging system events.
The BIOS logs system errors to the SEL. Be aware that error numbers for the same error may
be different depending upon whether the error was logged to the SEL or to the management
module (MM).
