6.2 Error Messages and Error Codes
The BIOS indicates the current testing phase during POST by writing a hex code to I/O location
80h. If errors are encountered, error messages or codes will either be displayed to the video
screen, or if an error has occurred prior to video initialization, errors will be reported through a
series of audio beep codes.
The error codes are defined by Intel and whenever possible are backward compatible with error
codes used on earlier platforms.
Most POST error codes are logged in the system event log.
6.2.1
POST Error Codes and Messages
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 system cannot boot unless the error is corrected.
