Chapter 1 Introduction
Welcom e to the PEAK 650 the most powerf ul Intel 815E based single boar d com puter.
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, f ull-size single board computer . The
Intel 815E chipset, which combining inter nal graphics, LAN, and support for 4 USB ports, Ul tra 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 control ler, 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 compatibl e with DVI spec if icati on 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 appl ications requiring addi tional texture memor y. The operating system requir es allocation of up
to 1MB of system memory to support legacy VGA. System properties will display up to 1MB less than
physical system memory avai labl e to the operating system . The graphi cs dri v er f or the Intel 815 conf i guration
will request up to 4MB of memory from the OS to implement a maximum 1024x 768 screen resolution, 2MB
for a command buffer and 4MB used for Z-buffering. For high-end 3D applications, the drivers request
allocation of system mem ory fr om the O/S for AGP graphics textures . W hen the 3D appli cation is closed, the
O/S will re-allocate system memory back for generic use.
With the on board NEXC OM proprietar y PCI Interface, the optional EBK SCSI 2 m odule desi gn 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 f eatur e 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 Li nux Oper ation system .

Chapter 3 Capability Expanding
This chapter explains how you can expand capability of your CPU board in such aspects as system memory
and CPU.
3-1 System Memory
Peak650 support 2 slots f or 168-pin 3.3V Non-regi stered DIMM modules , providing suppor t for up to 512M B
of main memory using DIMM modules from 8MB to 256MB. The following is the example to install the
system SDRAM mem ory module combinati on.
Note:
1. It is highly recommended to use the PC-100 or PC-133 Specification DIM M module.
2. Due to limitation of Intel 815E chipset, th e board can support the ECC memory module.
Q y of Module DIMM1 DIMM2
1 1 st 8~256 MB 256 MB
2 1 st 2 nd 8~256 MB 512 MB
To insert the DIMMs, the m odul es mus t be oriented in
the correct way. Notice the notches of the DIMM.
Align these notches as shown in the diagr am bel ow.
Gently push the DIMM until the r etai ner s on both
sides of the socket lock the m odule in pl ace.
To remove a DIMM , push the retainer s outwards to
release the module then pull the m odule out of the
socket.

To change the CPU, pull the handling bar of the socket upward to the other end to loosen the socket's
openings. Carefully lift the existing C PU up to r em ove it from the s ock et.
Removing CPU
Place the new CPU on the middle of the socket, orienting its beveled corner to line up with the socket's
beveled corner. Make s ure the pins of the CPU fit ev enly to the socket openi ngs. Replace the handling
bar to fasten the CPU to the socket. Be sure to re-arrange the jumper setting for the correct external
clock.

Advanced Chipset Features Setup Menu
Since the features in thi s sec ti on ar e related to the chipset in the C PU boar d and al l ar e opti m i zed, you are
not recommended to change the default settings in the setup tabl e, unless you know v ery detailed of the
chipset features.
This section allows you to configure the system based on the specific features of the installed chipset.
This chipset manages bus speeds and access to system memory resources, such as DRAM and the
external cache. It also coordi nates communications between the conv entional ISA bus and the PCI bus.
It must be stated that these items should never need to be altered. The default settings have been
chosen because they provide the best operating conditions for your system. The only time you might
consider making any changes would be if you discov ered that data was being los t while usi ng your system.
The first chipset settings deal with CPU acces s to dynamic random ac cess mem ory (DRA M). The default
timings have been carefully chosen and should only be altered if data is being lost. Such a scenario
might well occur if your system had mixed speed DRAM chips installed so that greater delays may be
required to preserve the integrity of the data held in the slower m em or y chi ps .

The Choice: 2, 3.
SDRAM RAS Precharge Time
If an insufficient number of cycles is allowed for the RAS to accumulate its charge before DRAM refresh,
the refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and
Slow gives more s table performanc e. This field appli es only when synchronous DRAM is instal led in the
