21) Digital Audio Interface Header (2-pin SPDO/SPDI)
This header is the digital link between the motherboard and your devices, such
as CD player, sampler, or DAT recorder. It allows the digital transmission of
audio data in SPDIF (Sony/Philips Digital Interface) format.

22) Chassis Intrusion Lead (2-pin ACHA)
This lead is for a chassis designed for chassis intrusion detection. After-market
toggle switches may also be installed to the chassis panel or on any removable
components. Two wires should be available from the chassis to connect to this
lead. When any chassis component is removed, the contact should open and the
motherboard will record a chassis intrusion event. The event can then be pro-
cessed by software such as LDCM. If the chassis intrusion lead is not used, a
jumper cap must be placed over the pins to prevent unnecessary power loss.
