Tamper detect switch
The tamper detect feature is triggered by the opening and closing of the lid. It is affected by a switch
mounted on the PCI Express module:

A tamper detection input is included within the real time clock circuitry of the ANTARES that operates
in all power modes. The status of the tamper detection bit is battery backed in static RAM. Using a
normally open switch, a tamper is detected when the switch contacts close.
The BIOS security setup screen provides two options for enabling a case open warning. It also
provides a secure chassis mode that requires the supervisor password to be entered and the chassis
intrusion detection to be disabled before the board will boot to an operating system. Both options are
disabled by default; refer to the ANTARES user manual for details.
