Appendix F: 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, you can customize a progress code 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 system BIOS or option ROMs may report progress codes.
The Response section in the following table is divided into three types:
• No Pause: The message is displayed on the screen or on the Error Manager screen.
The system continues booting in a degraded state. The user may want to replace the
erroneous unit. The POST Error Pause option setting in the BIOS setup does not have
any effect on this error.
• Pause: The message is displayed on the Error Manager screen, and an error is logged
to the SEL. The POST Error Pause option setting in the BIOS setup determines
whether the system pauses to the Error Manager for this type of error so the user can
take immediate corrective action or the system continues booting.
Note that for 0048 “Password check failed”, the system will halt and then after the next
reset/reboot, it displays the error code in the Error Manager screen.
• Halt: The system halts during post at a blank screen with the text “Unrecoverable fatal
error found. System will not boot until the error is resolved” and “Press <F2> to
enter setup” The POST Error Pause option setting in the BIOS setup does not have
any effect with this class of error.
After entering the BIOS setup, the error message displays on the Error Manager
screen, and an error is logged to the SEL with the error code. The system cannot boot
unless the error is resolved. The user must replace the faulty part and restart the
system.
