Supports AMD® Socket 462 Athlon™ & Duron™ 600MHz~1GHz+ with 266MHz EV6 Bus designed for Socket 462 technology.
Chipset
The VIA Apollo KT133 / KT133(A) is a high performance, cost-effective and energy efficient chipset for the implementation of
computer system with 266MHz system frequencies and based on 64-bit Socket 462 CPU. The VIA Apollo KT133 / KT133(A)
integrates VIA’s VT82C694X system controller and provides superior performance between the CPU, DRAM, AGP bus and PCI
bus.
Expansion Slots
Including three 32-bit/33MHz PCI and one AGP 4X slots. The PCI local bus throughput can be up to 132MB/s. The Accelerated

Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components.
Always observe the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist
strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection.

This motherboard supports AMD® Athlon and Duron Socket 462 series CPU and 200/266MHz EV6 bus. Be careful of CPU
orientation when you plug it into CPU socket. The following steps will guide you to finish CPU installation:
1. Pull up the CPU socket level and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the
CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into
the socket.
