Tsunami AT (S1830) 

  Benefits and Applications

Tyan Tsunami AT is a quality, high performance single processor system platform that supports the powerful Intel Pentium II / III microprocessors. This system platform is designed with the Intel 440BX AGPset.  Please refer to the Motherboard CPU Compatibility Chart for more specs.

The Tsunami AT supports SPD SDRAM  memory and  ECC SDRAM.  The board's PCI Local Bus and new 32-bit AGP bus provide high performance capabilities that are ideal for a wide range of applications for desktop and general users.

This integrated system board achieves the highest reliability and is based on a baby AT 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, on-board PS/2 mouse connector, and optional System Mangement.

Flexibility and expandibility are designed into the Tsunami AT. With I/O and drive controller support built on-board, the Tsunami AT allows many upgrade paths not found on other boards.. With four 168-pin DIMM sockets,  the Tsunami AT can provide a very flexible memory configuration of up to 1 GB  SPD SDRAM or SDRAM+ECC in addition to the 100 MHz SDRAMs (PC100 memory required for 100 MHz operation)
