23.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.
