& Case Open
Displays the detection status of the chassis intrusion detection device attached to the motherboard CI
header. If the system chassis cover is removed, this eld will show "Open", otherwise it will show "Close."
To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings
to the CMOS, and then restart your system.
& Reset Case Open Status
Disabled Keeps or clears the record of previous chassis intrusion status. (Default)
Enabled Clears the record of previous chassis intrusion status and the Case Open eld will
show "No" at next boot.
` H/W Monitor
