Appendix C: POST Error Messages and Handling
Whenever possible, 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. The class and subclass fields point to the type of hardware
being initialized. The operation field represents the specific initialization activity. Based on the
data bit availability to display progress codes, a progress code can be customized to fit the data
width. The higher the data bit, the higher the granularity of information that can be sent on the
progress port. The progress codes may be reported by the system BIOS or option ROMs.
The Response section in the following table is divided into three types:
Minor:
The message displays on the screen or in the Error Manager screen. The
system continues booting with a degraded state. The user may want to replace the
erroneous unit. The setup POST error Pause setting does not have any effect with this
error.
Major:
The message is displayed in the Error Manager screen and an error is logged to
the SEL. The setup POST error Pause setting determines whether the system pauses
to the Error Manager for this type of error where the user can take immediate corrective
action or choose to continue booting.
Fatal:
The message displays in the Error Manager screen, an error is logged to the
SEL, and the system cannot boot unless the error is resolved. The user must replace
the faulty part and restart the system. The setup POST error Pause setting does not
have any effect with this error.
