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.
