Viewing the Event Log
The BIOS-based event log records all firmware events, such as configuration changes, array
creation, and boot activity.
Some events are not stored indefinitely—the event log is cleared of any non-persistent events
each time you restart your computer; additionally, once the log is full, new events overwrite
old events.
To view the event log:
1 Start the utility (see page 69).
2 Select the controller you want, then press Enter.
3 When the utility menu appears, then press Ctrl+P.
4 Select Controller Log Information, then press Enter.
