POST Error Codes
During POST after the video has been initialized, the BIOS outputs the current boot progress codes on the
video screen. Progress codes are 32-bit quantities plus optional data. The 32- bit numbers include class,
subclass, and operation information. Class and subclass point to the type of the hardware that is being
initialized. Operation represents the specific initialization activity.
Based on the data bit availability to display the progress code, a progress code can be customized to fit the
data width. The higher the data bit, higher the granularity of allowable information. Progress codes may be
reported by system BIOS or option ROMs.
The response section in the following table is divided into three types:
WARNING:The message is displayed on screen and the error is logged to the SEL. The system will
continue booting with a degraded state.
Pause: The message is displayed on the screen and the boot process is paused until the appropriate input is
given to either continue the boot process or take corrective action.
Halt: The message is displayed on the screen, an error is logged to the SEL, and the system cannot boot
unless the error is corrected.
The error codes are defined by Intel and whenever possible are backward compatible with error codes used
on earlier platforms.
All POST error codes are logged in the System Event Log.

64bit data support in the BIOS. This message is displayed to indicate that EHCI controller is
disabled because of incorrect data structure. This condition will
occur if the USB host controller needs 64-bit data structure
while the USB is ported with 32-bit data structure.
