III. HARDWARE SETUP 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. NOTE: Pin 3 is removed to ensure the correct orientation of the cable on it. PC/PCI Request Sideband Signal DGND 2 6 PC/PCI Grant Sideband Signal 1 5 DGND Serial IRQ Connectors III.

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. +5Volt Standby Ground Chassis Signal MEL-M Chassis Open Alarm Lead ASUS MEL-M User’s Manual 29 M-LEM R 0 1 0 1 0 1 M-LEM R 0 1 0 1 0 1
