    440BX AGP OGIC HIPSET NTEL The Intel 440BX AGPset consists of the BX System Controller (443BX) and the PCI ISA IDE Xcelerator (PIIX4E/ PIIX4M). The AGPset forms a Host-to-PCI bridge and provides the second level cache control and a full function 64-bit data path to main memory.
  • Page 21 RIDGE CELERATOR The 2800 uses the 82371EB (PIIX4E) while the 2820 & 2850 use 82371MB (PIIX4M). The PCI ISA IDE Xcelerator (PIIX4E/PIIX4M) is a multi-function PCI device implementing a PCI-to-ISA bridge function, a PCI IDE function, a Universal Serial Bus host/hub function, and an Enhanced Power Management function. As a PCI-to-ISA bridge, the PIIX4E/PIIX4M integrates many common I/O functions found in ISA-based PC systems - a seven channel DMA Controller, two 82C59 Interrupt Controllers, an 8254 Timer/Counter, and a Real Time Clock.
