How do I enable the chassis intrusion detection feature on the B550 Tomahawk?
Connect the JCI1 connector to the chassis intrusion switch or sensor on the case, then go to BIOS > SETTINGS > Security > Chassis Intrusion Configuration and set Chassis Intrusion to Enabled. Press F10 to save and exit, and a warning message will appear on screen whenever the chassis cover is opened while the computer is on. (Page 24)
