The 82443LX (PAC) is the first generation of desktop AGPset designed for the Pentium II processor. The 82443LX PCI A.G.P. Controller (PAC) integrates a Host-to-PCI bridge, optimized DRAM controller and data path, and an Accelerated Graphics Port (A.G.P.) interface. A.G.P. is a high performance, component level interconnect, targeted at 3D graphics applications and based on a set of performance enhancements to PCI. The I/O subsystem portion of the PAC platform is based on the PIIX4, a highly integrated version of the Intel's PCI-to-ISA bridge family. PAC is developed as the ultimate Pentium II processor platform and is targeted for emerging 3D graphics and multimedia applications. The 440LX AGPset may contain design defects or errors known as errata which may cause the product to deviate from published specifications. Current characterized errata are available on request.
