System Board System Chipset System Chipset Memory Controller Hub (Intel 860) The MCH supports: • The 400 MHz (quad-pumped 100MHz) front side bus for up to two Intel dp Xeon processors • Two Rambus channels with up to 8 PC800 ECC RIMMs total • An Accelerated Graphics Port, AGP Pro 110 4x with 1.5V signaling only. • Two source-synchronous, enhanced, Hublink buses: - Hublink A is an 8-bit, 133 MB/s connection to the ICH2 - Hublink B is a 16-bit, 266 MB/s bus to the P64H PCI 64-bit Hub (Intel 82086) P64H provides the interface to the 64-bit, 66 MHz PCI bus with embedded SCSI controller chip and two 3.3 V PCI slots. When 33 MHz cards are present, the P64H detects this condition and lowers the bus frequency to 33 MHz. Only 3.3 V cards can be used. Interface Controller Hub (Intel 82801BA) The ICH2 is the interface to: • a 32-bit, 33 MHz PCI bus with embedded LAN and three 5 V PCI slots • Two ATA100 IDE Controllers, which support DMA transfers rates for up to four devices The IDE/ATA interface on the x4000 is provided primarily for use with optical devices 30 Chapter 2
