Tyan Tomahawk A+ S1856-V Motherboard

Tyan Tomahawk A+ is a quality, high performance single processor system platform based on the powerful Intel PPGA-370 Celeron microprocessors. This mainboard is designed around the latest and fastest Intel 440BX AGPset as well as VIA´s Apollo Pro Plus AGPset.

The Tomahawk A+ supports SPD SDRAM memory and ECC SDRAM. S1856's PCI Local Bus and new 32-bit AGP bus provides high performance capabilities that are ideal for a wide range of demanding applications such as: CAD, CAM, CAE, real-time 3D, and simulations.

This integrated system board achieves the highest reliability and is based on a double row 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, on-board PS/2 mouse connector, on-board wavetable sound (optional), and on-board system mangement (optional).

Flexibility and expandibility have been designed into the Tomahawk A+. With I/O and drive controller support built on-board, the Tomahawk A+ allows many upgrade paths not found on other boards.. With three 168-pin DIMM sockets, the board can provide a very flexible memory configuration of up to 768MB SPD SDRAM or SDRAM+ECC in addition to the new 100 MHz SDRAMs.
