VT8371 System Board 1
Chapter 1 Introduction
1-1 Main Board Overview
The K7VA133/VT8371 and VT82C686A chipset is a high performance, cost-
effective and energy efficient system controller for the implementation of AGP /
PCI / ISA desktop personal computer systems based on 64-bit Slot-A (AMD K7)
processors.
The K7VA133 supports three banks of SDRAMs up to 256MB. The SDRAM
controller supports standard either Synchronous DRAM(SDRAM) or Virtual
Channel Memory (VCM), in a flexible mix/match manner. The Synchronous
DRAM interface allows zero wait state bursting between the SDRAM and the data
buffers at 100 MHz.
The VT8371 system controller also supports full AGP v2.0 capability for
maximum bus utilization including 1x, 2x and 4x mode transfers. Both Windows-
95 VXD and Windows-98/Windows 2000 miniport drivers are supported for
interoperability with major AGP-based 3D and DVD-capable multimedia
accelerators.
The VT82C686A also includes an integrated keyboard controller with PS2 mouse
support, integrated DS12885 style real time clock with extended 256 byte CMOS
RAM, integrated master mode enhanced IDE controller with full scatter/gather
capability and extension to UltraDMA-33/66 for 33/66 MB/sec transfer rate,
integrated USB interface with root hub and four function ports with built-in
physical layer transceivers, Distributed DMA support, and OnNow/ACPI
compliant advanced configuration and power management interface. The
VT82C686A also includes an AC97/MC97 link for interface to external audio and
modem codecs, and all “Super-I/O” functions(serial ports, parallel port, and
floppy drive interface and game port).
