CPU
Supports AMD® Socket 462 series CPU with both 200MHz and 266MHz EV6 Bus designed for Socket 462 technology.
Athlon: 600MHz~1.4GHz
Duron: 600MHz~1.2GHz
AthlonXP: 1500+(1.3GHz)~1900+(1.6GHz)
Chipset
The VIA Apollo KT266A consists of the VT8366A V-Link DDR Host system controller and the VT8233A highly integrated V-Link
Client PCI/LPC controller. The Host system controller provides superior performance between the CPU, SDRAM, AGP bus, and
V-Link interface with pipelined, burst, and concurrent operation. The VT8233A V-Link Client controller is a highly integrated
PCI/LPC controller. Its internal bus structure is based on 66MHz PCI bus that provides 2x bandwidth compare to previous
generation PCI/ISA bridge chips. The VT8233A integrated Client V-Link controller with 266MB/s bandwidth between Host/Client
V-Link interface, provides a V-Link-PCI and V-Link-LPC controller. Of five PCI slots provided, AK77 Pro(A)-133 supports all five
master PCI slots with arbitration and decoding for all integrated functions and LPC bus; while AK77 Plus(A)-133 supports four
master PCI slots for arbitration and decoding functions also and one slave PCI slot.

Ultra DMA 66/100/133 Bus Mater IDE
Comes with an on-board PCI Bus Master IDE controller with two connectors that supports four IDE devices in two channels,
supports Ultra DMA 66/100/133, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 4, and supports Enhanced IDE devices.
Expansion Slots
Including five 32-bit/33MHz PCI, one CNR and one AGP 4X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR) slot provided from AK77 Pro(A)-133 / AK77 Plus(A)-133 can support CNR interface
for a Modem/Audio card. The Accelerated Graphics Port (AGP) specification provides a new level of video display sophistication
and speed. The AGP video cards support data transfer rate up to 1056MB/s. As AK77 Pro(A)-133 / AK77 Plus(A)-133 includes
one AGP expansion slot for a bus mastering AGP graphic card, For AD and SBA signaling, AK77 Pro(A)-133 / AK77 Plus(A)-133
can support 133MHz 2X/4X mode.
Memory
With VIA Apollo KT266A chipset, the AK77 Pro(A)-133 / AK77 Plus(A)-133 can support Double-Data-Rate (DDR) SDRAM. The
DDR SDRAM interface allows zero wait state bursting between the SDRAM and the data buffers at 66/100/133MHz. The six
banks of DDR SDRAM can be composed of an arbitrary mixture of 1M/2M4M/8M/16M/32M/64MxN DDR SDRAM and maximum
up to 3GB. The AK77 Pro(A)-133 / AK77 Plus(A)-133 allows DDR SDRAM to run at either synchronous or pseudo-synchronous
mode with the host CPU bus frequency (66/100/133MHz).

This chapter describes jumpers, connectors and hardware devices of this motherboard.
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 procedures requiring ESD protection.
