Description

The ^(R) Intel  440GX AGPset is intended for the Pentium^(R)   II processor and Pentium^(R)   II Xeon(TM)  processor platforms. The 82443GX Host Bridge provides a Host-to-PCI bridge, optimized  DRAM controller and data path, and an Accelerated Graphic Port (AGP) interface. AGP is a high performance, component level interconnect targeted at 3D graphics applications and is based on a set of performance enhancements to PCI.

The I/O subsystem portion of the Intel ^(R) 440GX AGPset platform is based on the 82371EB
(PIIX4E), a highly integrated version of the Intel's PCI-ISA bridge family.
