Tahoe Plus ATX (S1686S) 

  Benefits and Applications

Tyan Tahoe Plus ATX is a quality, high performance single processor system platform based on the powerful Intel Pentium II with Pentium Pro microprocessor support. This mainboard is designed around the latest and fastest Intel 440FX chipset and can support Pentium II CPU speeds of 233 MHz through 300 MHz.

The Tahoe Plus ATX supports EDO memory, ECC and memory parity checking.  The board's PCI Local Bus provides high performance capabilities that are ideal for a wide range of demanding applications such as: CAD, CAM, CAE, networking, multi-user environments, database management, desktop publishing, image processing and 3D animation.

This integrated system board achieves the highest reliability and is based on an ATX form factor. Some of the features included are: on-board dual channel PCI IDE, on-board floppy controller, on-board high speed I/O, Universal Serial Bus and on-board PS/2 mouse connector.

Flexibility and expandibility have been designed into the Tahoe Plus ATX. With I/O and drive controller support built on-board, the Five PCI and Three ISA (One ISA and one PCI as a shared slot) slots are free for add-on expansion cards. With eight SIMM sockets, the Tahoe Plus ATX can provide a very flexible memory configuration of 8MB to 1GB of RAM.
