Introduction

80486VESA Motherboard Overview

The 80486VESA system board is a high performance, function

enchanced computer system board that combines the power of

Intel’s new 80486 CPU and the VESA VL-bus. The board design

includes a variety of high-powered features. Its high performance

capability can provide an ideal system board solution for a wide

range of demanding applications like CAD/CAM/CAE, database

management, image processing, artificial intelligence, desktop

publishing, and the environments of network and multiuser

systems. The 80486VESA system board fully utilizes the 32-bit

CPU power.

The 80486VESA system board also incorporates an Intel 80486

microprocessor which has an 8 KByte static RAM cache. Included

is a four-way set associative cache controller implemented on the

80486 chip and an internal enhanced numeric coprocessor unit.

The system also has an option to accommodate 64KB, 128KB, and

256KB of external cache.

Because of its unique memory subsystem design, the 80486VESA

allows for 1 Megabyte to 32 Megabytes of 32-bit high speed

memory by using 256KB, 1MB, and/or 4MB SIMM modules.
