ASUS CIDB Module
7.2.2 Setting up the ASUS CIDB
7.2.3 ASUS CIDB Additional Considerations
1. If there is no power to the motherboard (i.e. removing 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 will detect on the next bootup.
2. Any chassis intrusion detection components on the motherboard will not work if
the CIDB is used.
3. The P2B-LS motherboard must use an external battery pack on the EXTBATT
connector or else neither the alarm or intrusion memory functions will work.
5. To stop the alarm from sounding, use the BIOS setup or momentarily place a
jumper on (or short manually) the CLR jumper. Note that the jumper must be
removed for the CIDB to work normally again.
6. If you have an updated BIOS with intrusion support, booting the computer after
an intrusion may require a password if configured through BIOS.
