Introduction
Thank you for choosing this mainboard. It is a high performance
and high quality mainboard which is built around the latest and
fastest VIA VT8235 chipset providing superior
performance between the CPU, DRAM, AGP bus, and V-Link bus
with pipelined, burst and concurrent operation. This mainboard
supports Socket 462 that accommodates AMD Athlon processors
with a frontside bus (FSB) speeds up to 133MHz.
The KT266A supports two banks of DDR Synchronous DRAMs
up to 2GB for unbuffered modules. It also fully supports full AGP
v2.0 capability for maximum bus utilization including 1x, 2x and
4x mode transfers, SBA (SideBand Addressing), Flush/Fence
commands and pipelined grants.
The VT8235 Southbridge supports standard intelligent peripheral
controllers such as USB v2.0/1.1 and Universal HCI v2.0/1.1
compliant, real time clock with 256 byte extended CMOS,
integrated bus-mastering dual full-duplex direct-sound AC97 link
compatible sound system and full System Management Bus
(SMBus) interface.
Sufficient expansion is provided for with one AGP slot, five 32-bit
PCI slot and an optional CNR slot. It also comes with a built-in
Enhanced PCI Bus Master PCI IDE controller that provides high-
speed connections to full range of IDE devices such as HDD and
CD-ROM. This mainboard is designed in a standard ATX form
factor using a 4-layer printed circuit board and measures 305 mm x
190 mm.
