Default BIOS Power-On Self-Test (POST) Events

At system startup, the BIOS performs a power-on self-test that checks the hardware on your server to ensure that all components are present and functioning properly. The following table identifies the events that can occur during BIOS POST, and specifies whether these event can prevent the host from powering on.

Boot continues on host?
User password violation
Attempt to enter password fails three times.
Setup password violation
Attempt to enter password fails three times.
Correctable ECC
Correctable ECC (error correction code) error detected.
Uncorrectable ECC
Uncorrectable ECC error detected.
No system memory
No physical memory detected in the system.
No usable system memory
All installed memory has experienced an unrecoverable failure.
Boot media failure
No removable boot media is found.
CMOS set to optimal defaults
Load optimal defaults.
CMOS time and data error
RTC is invalid.
IOH errors reported
IOH errors.

Does not apply
Not enough option ROM space allocated for device
BIOS cannot copy an option ROMs content to the memory. This is likely due to a large number of EMs (express modules) attached to the system.
Maybe booting over an EM not possible.

Soft-off power on (S0) or off (S5).
Does not apply
Not enough IO address space allocated for device
Cannot allocate resources to an on-board device (PEM, REM, FEM), and slot is disabled.
