Error Classes - HP Xw8400 - Workstation - 4 GB RAM Technical Reference Manual

uncorrectable non-fatal errors are masked so they are logged, but will not generate an Err0. Unlike
correctable non-fatal errors, the uncorrectable non-fatal errors will automatically force an F1 Boot prompt
on the next reboot.
Fatal errors are not masked.
When errors are detected and not masked, they generate an Err0 signal. There are four ways to handle
this type of error.
●
Ignore (mask out the error)
● Generate an SMI which results in a reboot
●
Generate an NMI which results in a crash
●
Generate a Machine Check which results in a crash
Default is to generate an SMI. Use the Advanced > Chipset option in the F10 Setup menu to control
this type of error.

Error classes

There are two major classes of errors—fatal and non-fatal.
All fatal errors generate error 922-Fatal error on (subsystem is identified)
Non fatal errors generate a different error number for each subsystem and for correctable and
uncorrectable error types:

923 Non-fatal
924 Non-fatal
925 Non-fatal
926 Non-fatal
