9.3 Bug Check Causes
Bug check causes are the causes of occurrence when a bug check (blue screen) occurs.
These values are logged to a memory dump file when a blue screen occurs, and a distinguishable name
(NMI_HARDWARE_FAILURE or WHEA_UNCORRECTABLE_ERROR) appears on the screen.
In addition, the digital LEDs for status indications that are installed in this equipment show codes that correspond to
the causes of occurrence for bug checks (blue screens).
Although multiple bug check causes exist, you can determine the detailed information by checking the event log
(event ID: 800, source: HFWRAS_SYS).
