BIOS POST Event Messages

BIOS POST Event Message	Cause
`ACPI Power state`	User has configured a soft power-off.
`Boot media failure`	No bootable media was found. BIOS was configured to boot off of removable media, yet none is available. Alternatively, bootable media is available, but lacking true boot capability.
`Correctable ECC`	A correctable ECC error was detected in memory. A memory cell has failed in a DIMM, but was corrected.
`Embedded controller management`	Hardware management controller was initialized.
`Firmware (BIOS) ROM corruption`	BIOS checksum fails although the boot block might not be corrupted. The boot process terminates.
`Hard disk controller failure`	No disk controller was found. If a disk controller is currently installed, it is either disabled or defective.
`Initiated by hard reset`	Boot process was started by a hard reset. This message might be seen at initial power on.
`Initiated by warm reset`	Boot process was started by a warm reset.
`Keyboard controller initialization`	Keyboard controller is being initialized.
`Keyboard failure`	Keyboard cannot be initialized. Alternatively, the keyboard is unplugged.
`Memory initialization`	Memory configuration is being sized.
`No bootable media`	There are no bootable media sources configured, enabled, or available. Alternatively, bootable media is available, but lacking true boot capability. The boot process terminates.
`No system memory`	No physical memory was detected in the system. If DIMMS are currently installed, they are of an unsupported architecture or completely defective. The boot process terminates.
`No usable system memory`	All installed memory has experienced an unrecoverable failure. The failure of one or more DIMMs puts the remaining DIMMs into an unsupported configuration. The boot process terminates.
`No video device`	No video controller was found. If a video controller is currently installed, it is either disabled or defective. The boot process terminates.
`Option ROM initialization`	Option ROMs are being initialized.
`Option ROM space exhausted`	Memory space allocated for BIOS options is full and writes to the space cannot continue. The remaining options are not configured.
`Primary processor initialization`	Primary CPU is being initialized.
`PXE server not found`	BIOS was configured to boot from a PXE server, however the PXE server was not found, or the PXE server did not have the supported protocols or files available. The boot process terminates.
`Secondary processor(s) initialization`	Secondary CPUs are being initialized.
`Setup password violation`	An attempt to enter the setup password has failed three times in a row. The boot process terminates.
`System restart`	System boot was initiated.
`Uncorrectable ECC`	An uncorrectable ECC error was detected in memory. A memory cell has failed in a DIMM, and was not corrected.
`User initiated boot to OS`	User has initiated a boot to the operating system.
`User initiated system set up`	User has initiated access to the BIOS setup utility.
`User password violation`	An attempt to enter the user password has failed three times in a row. The boot process terminates.
`Video initialization`	Video controller is being initialized. This occurs during the keyboard controller initialization.
