Motherboard
All control and datapath functionality, with the exception of the disk connectors and CPU module boards, reside
on the motherboard. There are sockets for connecting each of the 8 CPUs that are interconnected through AMD's
HyperTransportTM technology. There are also HyperTransport links to the PCI-X bridge and the Southbridge
chipsets. All external connections, with the exception of power, disks, and front panel I/O, come into the
motherboard.
