* Pentium is a registered trademark of Intel Corporation.

 The CM-i786 Module is a small but extremely powerful PC-compatible single board computer, designed to serve as a building block in variety of embedded applications. The CM-i786 module has all the components needed to run operating systems such as Windows XP / CE, Linux, VxWorks or DOS. Ready BIOS and operating systems packages are available from CompuLab.

The CM-i786 is both small and inexpensive relatively to products of its class. Its size, slightly larger than a credit card, allows integration into compact embedded applications where extraordinary processing power is required.

The feature set of the CM-i786 module includes practically all of the components found in a high-end seventh-generation desktop computer. For embedded applications, the CM-i786 provides a Flash Disk, PCI bus, two 100Mbit Ethernet ports, UART's, I/O lines and many other essential functions.

Software support for the CM-i786 includes ready-to-run packages for:

* Linux
* Windows CE & XP
* VxWorks
* DOS with networking
