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
