Introduction
Welcome to the most powerful Intel 815E based single board computer.
The CPU board combines the high performance and exceptional value of Intel Celeron / Pentium III CPU
and 815E chipset with a full-featured, new generation, full-size single board computer. The Intel 815E
chipset, which combining internal graphics, LAN, and support for 4 USB ports, Ultra DMA66/100 IDE
interface, that meets the performance, stability and reliability requirements. Moreover, In order to meet the
network requirement, the CPU boards add one more Ethernet Controller Intel 82559 to support dual channel
Ethernet.
For the Display solution, not only the Intel 82815 (GMCH) chipset integrated Graphics controller, the CPU
board also provide On Board Optional ATI Rage Mobility M4 3D VGA accelerator with on die 8MB or 16MB
memory to support 4X AGP, which is compatible with DVI specification to support LCD panel.
The Intel 82815 (GMCH) chipset integrated Graphics with Intel Dynamic Video Memory Technology, the
D.V.M.T. employs direct AGP and intelligent arbitration to dynamically allocate and de-allocate memory for
textures for applications requiring additional texture memory. The operating system requires allocation of up
to 1MB of system memory to support legacy VGA. System properties will display up to 1MB less than
physical system memory available to the operating system. The graphics driver for the Intel 815
configuration will request up to 4MB of memory from the OS to implement a maximum 1024x768 screen
resolution, 2MB for a command buffer and 4MB used for Z-buffering. For high-end 3D applications, the
drivers request allocation of system memory from the O/S for AGP graphics textures. When the 3D
application is closed, the O/S will re-allocate system memory back for generic use.
The board is suitable and valuable for all the embedded applications, which also well support with the
Windows 2000, Windows NT and Linux Operation system.
