VIA KM266 Chipset

The VIA ProSavageDDR™ KM266 is an efficient, low-power, cost-effective chipset solution for systems based on the AMD Athlon™ XP and Duron™ Socket A processors, across a full spectrum of applications. With 2.1 GB/s of memory bandwidth and support for up to 4GB DDR266 SDRAM, the VIA KM266 also has a 266/200 MHz front side bus. The integrated S3 Graphics ProSavage8™ 2D/3D Accelerator with internal AGP 8X bandwidth and DVD Motion Compensation is optimized for use with the Microsoft Windows® XP operating system. Shared Memory Architecture (SMA) enables the ProSavageDDR KM266 to utilize the system memory for frame buffer and texture memory on a 128-bit internal data path.

The VIA KM266 also makes use of VIA's V-Link Hub Architecture, which provides a dedicated 266MB/s bus between the north and south bridge. Paired with any of the VIA V-MAP 8233 Series South Bridges, the VIA KM266 chipset also includes integrated 2 Channel AC'97 Audio, integrated MC'97 Modem, support for ATA 33/66/100, and support for 4 or more USB ports. Options include an integrated 3Com® networking MAC and ATA-133 Fast Drive™ depending on your design priorities.
