The S1854 Trinity 400 is a quality, high performance motherboard designed for Socket 370 Intel Celeron and Slot 1 Intel PII/ PIII microprocessors. The Trinity 400 utilizes the VIA VT82C694X with Award BIOS for S1854 & S1854-A models. S1854 can support Celeron/ PII/ PIII CPU speeds of 300MHz through 750MHz, and host bus speeds of 66MHz to 133MHz, the VIA chipsets bus speed is Auto-Determined by the CPU. The S1854 motherboard, with built-in 4x 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, 3D Games and video production. This system board in an ATX form factor offers far more features and expandability than Micro ATX models. Some of the features included are onboard dual channel PCI PIO, Bus Master IDE and UltraDMA/66, onboard floppy controller, and onboard high speed I/O. Flexibility and expandability have been designed into the Trinity 400. With I/O and drive controller support built onboard, the one AGP slot, six PCI, a total of seven usable are free for numerous add-on expansion cards.
