  Benefits and Applications

Tyan Trinity 100AT is a quality, high performance system platform that supports the Intel Pentium, Pentium MMX, AMD K5/K6/K6-2, Cyrix/IBM M1/M2, and IDT Winchip. This board utilizes the VIA Apollo MVP3 100 MHz chipset and supports frontside bus speeds up to 100 MHz. (PC100 memory required for 100 MHz FSB feature)  Please refer to the Motherboard CPU Compatibility Chart for more specs.

The Trinity 100AT's PCI Local Bus provides high performance capabilities that are ideal for a wide range of demanding applications such as: general, business, and gaming. This system board achieves high reliability with numerous features and yet is small enough to be supported in an AT form-factor.

Some of the features included are: on-board dual channel PCI IDE PIO, IDE DMA and IDE UltraDMA/33, on-board floppy controller, on-board high speed I/O, and a switching power supply to deliver unparalleled support for emerging CPU technologies.

Flexibility and expandability have been designed in the Trinity 100AT. With I/O and drive controller support built on-board, the four PCI and four ISA (One ISA and one PCI as a shared slot) slots are free for numerous add-on expansion cards.
