PCI Local Bus Interface

The Pentium design uses the 440BX chip set. The 440BX integrates a high perform-
ance interface from PCI to IDE. This interface is capable of accelerated data transfers.
The 440BX chipset provides an accelerated PCI-to-ISA interface that includes
·
A high-performance enhanced IDE controller
·
PCI and ISA master/slave interfaces
·
Plug-and-play port for on-board devices
The chipset also provides many common I/O functions found in ISA-based PC sys-
tems, including
·
Seven-channel DMA controller
·
Two 82C59 interrupt controllers
·
8254 timer/counter
·
Control logic for NMI generation

XGA Graphics Controller

The PCI bus controller supports CRT displays and flat panel displays with 2 MB
video memory. The controller also supports resolutions of 640x480, 800x600, and
1024x768 with 64K colors.

Fast IDE controller

The high-speed local bus IDE controller supports programmed I/O (PIO) modes 0-4.
It also provides 4x32-bit read-ahead buffer and 4x32-bit write-post buffer support to
enhance IDE performance.
