  Benefits and Applications

Designed for cost-effective multimedia desktop PC systems, Tyan Tomcat i810ef delivers substantially faster performance than on boards uing the  Intel 810 AGPset.  The Tomcat i810ef  includes integrated Intel 3D graphics, AC'97 audio, and UDMA/66 IDE controllers.  This product also includes onboard 10/100 Mbps LAN as a manufacturing option.  All of these features combine to make the ideal all-in-one desktop PC.

The Tomcat i810ef supports PC100 SDRAM  memory.  The board's PCI Local Bus and onboard Intel 3D Graphics accelerator provides graphics performance for appliance PC applications and other small footprint solutions.

This integrated system board achieves the highest reliability and is based on a double row flex-ATX form factor. Some of the features included are: on-board dual channel PCI IDE,  floppy controller, high speed I/O, Universal Serial Bus, PS/2 mouse connector, AC-97 sound, onboard 4 MB Display Cache, and Audio Modem Riser support.

Flexibility and expandibility have been designed into the Tomcat i810ef. With I/O and drive controller support built on-board, the Tomcat i810ef allows many upgrade paths not found on other flex-ATX boards.. With two 168-pin DIMM sockets,  the Tomcat i810ef can provide a memory configuration of up to 512 MB  PC100 SPD SDRAM.
