18. Wake-On-Ring Connector (2-pin WOR)
This connector connects to an internal modem card with a Wake-On-Ring output.
The connector powers up the system when a ringup packet or signal is received
through the internal modem card. NOTE: For external modems, Wake-On-Ring
is detected through the COM port.
IMPORTANT: This feature requires that PWR UP On Modem Act Power Up
Control is set to Enabled (see Power Management Setup under BIOS SETUP)
and that your system has an ATX power supply with at least 720mA +5V standby
power.

19. Chassis Intrusion Sensor Lead (optional) (4-1 pin CHASIS)
This lead is for a chassis intrusion monitor or sensor. The sensor is triggered
when a high level signal is sent to the "chassis signal" lead. This occurs when a
panel switch or light detector is triggered. This function requires the optional
