ASUS CIDB Additional Considerations
1. All motherboards with CIDB: If there is no power to the motherboard (i.e. re-
moving the power cord or turning the power supply's switch off) the alarm will
not sound but the CIDB will still memorize an intrusion event which BIOS and
LDCM will detect on the next bootup.
2. Motherboard with chassis intrusion components: Photo sensor, switch, and
memory will not operate with power removed. Power is required to send a signal
to the motherboard's intrusion memory and buzzer. When using the CIDB on
these motherboards, all the CIDB functions will be disabled, the motherboard's
intrusion components must still be used. The CIDB can benefit these mother-
boards by providing a chassis switch which will operate even when the power is
removed. Pins [2-3] of the SW jumper can be used for a momentary toggle switch
and the CIDB's battery will be used to send an intrusion signal to the motherboard's
intrusion memory.
