15. SB-Link™ Connector (6-1 pin SBLINK)
Using Intel’s PC-PCI and serialized IRQ protocols found in this motherboard’s
AGPset, this connector allows Sound Blaster 16 compatibility to AWE64D (Digi-
tal) or other PCI audio cards, enabling users to play Real-mode DOS games and
multimedia applications. SB-Link acts as a bridge between the motherboard and
the PCI audio card by providing the DMA and IRQ signals present in the ISA
bus but not available on the PCI bus.

16. Chassis Intrusion Sensor Lead (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
ASUS CIDB Chassis Intrusion Sensor Module (see APPENDIX) to be installed.
