Chipset
The Intel 440BX chipset was designed for the Pentium II
processor. It consists of the Intel 82440BX PCI/AGP
controller (PAC) and the Intel 82371EB PCI/ISA IDE
Xcelerator (PIIX4E) bridge chip.
Intel 82440BX PCI/AGP Controller (PAC)
The PAC provides bus-control signals, address paths, and
data paths for transfers between the processor’s host bus, PCI
bus, Accelerated Graphics Port (AGP) and main memory.
The PAC provides the following features:
„
Processor interface control

Processor host bus speeds of 66 MHz and 100 MHz

32-bit addressing

GTL+ compliant host bus
„
Integrated DRAM controller

Supports 100-MHz and 66-MHz synchronous DRAM
(SDRAM)

64/72-bit path to memory

Auto detection of memory type

Supports 4-, 16-, 64-and 128-Mbit DRAM devices

Symmetrical and asymmetrical DRAM addressing

Supports 3.3 V DRAMs
