Benefits and Applications
Tyan Tomahawk BX is a quality, high performance single processor system
platform that supports the powerful Intel?PPGA-370 Celeron
microprocessors. This board is designed around the Intel 440BX AGPset as
well as VIA's Apollo Pro Plus chipset. Please refer to the Motherboard CPU
Compatibility Chart for more specs.
The Tomahawk BX supports SPD SDRAM memory and ECC SDRAM. The board'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: basic business and general operations.
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, on-board PS/2 mouse connector, on-board wavetable
sound (optional), and on-board system mangement (optional).
Flexibility and expandibility are present in the Tomahawk BX. With I/O
and drive controller support built on-board, the S1856S allows many
upgrade paths not found on other boards.. With three 168-pin DIMM sockets,
the Tomahawk BX can provide a very flexible memory configuration of up to
768 MB SPD SDRAM or SDRAM+ECC in addition to the new 100 MHz SDRAMs.
