System Chipset

The Intel I850 chipset is a high-integration chipset designed for graphics/multimedia PC

platforms and is comprised of the following:

• The 82850 MCH is a bridge between the:

— System bus

— Dual Rambus bus (main memory)

— AGP 4x (graphic) bus

— Hub link 8-bit

For detailed information about the MCH chip feature, see page 38.

• The 82801BA ICH2 is a bridge between the 32-bit, 33MHz PCI bus and the SMBus.

Additionally, the ICH2 supports the:

— integrated IDE controller (Ultra ATA/100)

— enhanced DMA controller

— USB controller

— interrupt controller

— Low Pin Count (LPC) interface

— FWH interface

— Integrated LAN

— ACPI Power Management Logic

— AC’97 2.1 Compliant Link

— Alert-On-LAN (AOL) and Real Time Clock (RTC)

— CMOS

For detailed information about the ICH2, see page 44.

• The 82802AB FWH stores system BIOS and SCSI BIOS (i.e., the nonvolatile

memory component). In addition, the FWH contains an Intel Random Number

Generator (RNG). The RNG provides random numbers to enable fundamental

security building blocks for stronger encryption, digital signing, and security

protocols for the workstation. For detailed information about the FWH, see page 56.
