Introduction

The 80486 Deep Green mainboard is a 32-bit high-performance

system board. This mainboard is not only compatible with

IBM AT systems, but it also provides power-saving features

that allow the user to program the timer.

You can configure the 80486 Deep Green mainboard for use with

many 486based microprocessors, such as the following:

Intel P24T

Intel P24D

Intel 80486DX4 (P24C)

Intel 80486DX2/DX/SX-SL

Intel 80486DX2 / DX /SX

CyrixCX486DX2/DX/S

AMD AM486DX4/DX2/DX

UMC U5

The 80486 Deep Green mainboard features on-board power
management that allows the user to assign system clock rates,

hard disk power saving and display power saving when
entering doze mode, suspend mode or inactive mode.
