Overview
The S1857 Trinity 371 is a quality, high performance motherboard designed for
Socket 370 Intel Celeron and Slot 1 Intel PII/ PIII microprocessors. The Trinity
371 utilizes the Intel 440BX AGPset with AMI BIOS (S1857-B & S1857A-B) or
a VIA VT82C693A with Award BIOS for S1857 & S1857-A models. S1857 can
support Celeron/ PII/ PIII CPU speeds of 300MHz through 600MHz, and host
bus speeds of 66MHz to 133MHz.
( The VIA chipset versionî‚’s bus speed is Auto-Determined by the CPU. The
BX version can support 133Mhz by overclocking the chipset but it is not
recommended by IntelTM and Tyan.)
The S1857 motherboard, with built-in AGP slot, provides high performance
capabilities that are ideal for a wide range of demanding applications such as
CAD, CAM, CAE, desktop publishing, 3D animation, and video production.
This system board in an ATX form factor offers far more features and
