BIOS POST Errors

Each power-on self-test (POST) diagnostic is a low-level test designed to pinpoint faults in a specific hardware component. If a POST diagnostic discloses an error, it typically reports the following information about the error:

Type of error detected
When or where the error occurred

The following table lists some of the error messages that might appear during the POST diagnostics, and provides instructions for resolving the errors.

Note - Contact Oracle Service for information about interpreting and applying the Oracle ILOM log information that you receive on these errors.

BIOS POST Error Message	Error Type	Resolution
Uncorrectable Error Detected on Last Boot:IOH(0) Protocol Error (Please Check SP Log for more Details)	IOH error	Check the SP event log in Oracle ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) QPI [`x`] Error (Please Check SP Log for more Details) Note - Where QPI [ `x`] equals 0 for QPI Link 0 or 1 for QPI Link 1.	IOH error	Check the fault management function and the SP event log in Oracle ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) PCI-E [`x`] Error (Please Check SP Log for more Details) Note - Where PCI-E [ `x`] port number can range from 1 to 10 depending on the PCI root port on IOH.	IOH error	Check the fault management function and the SP event log in Oracle ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) ESI Error (Please Check SP Log for more Details)	IOH error	Check the fault management function and the SP event log in Oracle ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) Thermal Error (Please Check SP Log for more Details)	IOH error	Check the fault management function and the SP event log in Oracle ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) Miscellaneous Error (Please Check SP Log for more Details)	IOH error	Check the fault management function and the SP event log in Oracle ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) VT-d Error (Please Check SP Log for more Details)	IOH error	Check the SP event log in Oracle ILOM for more details.
BMC Not Responding	ILOM error	This error message might appear if an internal error occurs during the SP/BIOS communication. This error might require you to restart the SP.
Hard disk error	SAS error	Check the SP event log in Oracle ILOM for more details. Note - These error messages appear when the BIOS is attempting to configure SAS devices in POST.
Bad PBR sig	Hard disk error	This is caused by a corrupted or nonexistent partition table on the disk drive. A disk utility (Oracle Solaris format or Linux fdisk) must be used to format the tables again.
RAM R/W test failed	Memory test failure	Check the SP event log in Oracle ILOM for more details. Note - This type of error typically indicates that the RAM read/write test failed.
CMOS Battery Low	CMOS battery error	Check the SP event log in Oracle ILOM for more details. If necessary, replace CMOS battery.
CMOS Checksum Bad CMOS Date/Time Not Set	CMOS error	Check the SP event log in Oracle ILOM for more details.
Password check failed	Password check error	Check the SP event log in Oracle ILOM for more details. Note - This type of error indicates that the password entered does not match the password specified in the BIOS setup utility. This condition might occur for both Supervisor and User password verification.
