The Intel 440LX chipset was designed for the Pentium II
processor. It consists of the Intel 82443LX PCI/A.G.P.
controller (PAC) and the Intel 82371AB PCI/ISA IDE
Xccelerator (PIIX4) bridge chip.
Intel 82443LX PCI/A.G.P. 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 comes in a 492-pin BGA package and
