Introduction
Welcome to the PEAK 650 the most powerful Intel 815E based single board computer.
NEXCOM’s PEAK 650 series 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 PEAK 650 series 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, PEAK 650
series 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.
With the on board NEXCOM proprietary PCI Interface, the optional EBK SCSI 2 module design with Adaptec
AIC-7890 Ultra 2 SCSI controller, and the module EBK SCSI 160D design with Adaptec AIC 7899 Dual Ultra
160 SCSI controller, giving the PEAK 650A a unique feature as a full function single board computer,
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.
