BIOS POST F1 and F2 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 F1 or F2 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 F1 and F2 error messages that could appear during the POST diagnostics and instructions for how to possibly resolve the error reported.

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	Press F1 to continue. Check the SP event log in 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	Press F1 to continue. Check the fault management function and the SP event log in ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) PCIe [`x`] Error (Please Check SP Log for more Details) Note - Where PCIe [ `x`] port number can range from 1 to 10 depending on the PCI root port on IOH.	IOH error	Press F1 to continue. Check the fault management function and the SP event log in ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) ESI Error (Please Check SP Log for more Details)	IOH error	Press F1 to continue. Check the fault management function and the SP event log in ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) Thermal Error (Please Check SP Log for more Details)	IOH error	Press F1 to continue. Check the fault management function and the SP event log in ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) DMA Error (Please Check SP Log for more Details)	IOH error	Press F1 to continue. Check the SP event log for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) Miscellaneous Error (Please Check SP Log for more Details)	IOH error	Press F1 to continue. Check the fault management function and the SP event log in ILOM for more details.
Uncorrectable Error Detected on Last Boot:IOH(0) VT-d Error (Please Check SP Log for more Details)	IOH error	Press F1 to continue. Check the SP event log in ILOM for more details.
BMC Not Responding	ILOM error	Press F1 to continue. Note - This error message might appear if an internal error occurs during the SP/BIOS communication. This error might require you to restart the SP.
Primary Master Hard Disk Error Primary Slave Hard Disk Error Secondary Master Hard Disk Error Secondary Slave Hard Disk Error	IDE/ATAPI error	Press F1 to continue. Check the SP event log in ILOM for more details. Note - These error messages appear when the BIOS is attempting to configure IDE/ATAPI devices in POST.
Timer Error	8254 timer error	Press F1 to continue. Check the SP event log in ILOM for more details. Note - This type of error typically indicates an error while programming the count register of channel 2 of the 8254 timer. This could indicate a problem with system hardware.
RAM R/W test failed	Memory test failure	Press F1 to continue. Check the SP event log in ILOM for more details. Note - This type of error typically indicates that the RAM read/write (R/W) test failed.
KBC BAT Test failed	Keyboard controller basic assurance test error	Press F1 to continue. Check the SP event log in ILOM for more details. Note - Keyboard controller BAT test failed. This error might indicate a problem with keyboard controller initialization.
Display memory test failed	Video display error	Press F1 to continue. Check the SP event log in ILOM for more details.
CMOS Battery Low	CMOS battery error	Press F2 to enter BIOS Setup utility to load system defaults. Check the SP event log in ILOM for more details. If necessary, replace CMOS battery.
CMOS Checksum Bad CMOS Date/Time Not Set	CMOS error	Press F2 to enter BIOS Setup utility to load system defaults. Check the SP event log in ILOM for more details.
Password check failed	Password check error	Press F1 to continue. Check the SP event log in ILOM for more details. Note - This type of error indicates a password entered does not match the password specified in the BIOS Setup utility. This condition might occur for both Supervisor and User password verification.
Keyboard/Interface Error	Keyboard controller error	Press F1 to continue. Check the SP event log in ILOM for more details. Note - This type of error indicates a Keyboard Controller failure. This error might indicate a problem with the system hardware.
