Collecting System Event Log (SEL) for Investigation
Whenever possible, the BIOS will output 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 that is 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 3 types:
1
Warning
or
Not an error
– The message is displayed on the screen. An
error record is logged to the SEL. The system will continue booting
with a degraded state. The user may want to replace the erroneous unit.
2
Pause
– The message is displayed on the screen, an error is logged to
the SEL, and user input is required to continue. The user can take
immediate corrective action or choose to continue booting.
3
Halt
– The message is displayed on the screen, an error is logged to the
SEL, and the system cannot boot unless the error is resolved. The user
needs to replace the faulty part and restart the system.
