22. SB-Link™ Connector (6-1 pin DMA_HEADER) (optional/reserved)

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.

23. SMBus Connector (3-pin SMB) (optional/reserved)

This connector allows you to connect SMBus devices. SMBus devices commu-

nicate by means of the SMBus with an SMBus host and/or other SMBus de-

vices. The SMBus or System Management Bus is a specific implementation of

an I

C bus, which is a multi-master bus, that is, multiple chips can be connected

to the same bus and each one can act as a master by initiating data transfer.
