Chapter 1
1-1 Introduction
The PEAK 632A is a full size Sing l e Bo a r d Comput e r . It applies Single Soc k e t 370
FC-PGA based processor, supporting both 66 MHz (Celeron) and 100 MHz (Pentium
III) Front Side Bus. The memory it can accommodate is 1 GB SDRAM up to 100
MHz.
Meanwhile, this card is on-board with the following three significant I/Os which help
to spare out more PCI slots for other add-on I/Os, i.e. the C&T 69000/69030
VGA/Panel controller through AGP interface; the Intel 82559 Ethernet and the
Adaptec 7890 Ultra 2 SCSI. Components with all o f the abo v e branded and
powerful. PEAK 632A is obv i ously a form i da bl e pla t f o r m ideal for heavy duty and
computer telephony application.
The other on-board I/Os includes 2S1P, the high precision RTC with battery, the
Watch Dog Timer, DOC, IDE×2, FDC×1, USB×2, and PS/2 Keyboard/Mouse.

Capability Expanding
This chapter explains how you can expand capability of your CPU board in such
aspects as system memory, cache memory, and CPU.
3-1 System Memory
Your system memory is provided by DIMM's (Dual In-line Memory Modules) on the
CPU board. The CPU board contains four memory banks: Bank 0, 1, 2, 3,
corresponds to connector DIMM1, DIMM2, DIMM3 and DIMM4.
The table below shows possible DIMM configurations for the memory banks.
You can also use the DIMM with parity check. The ECC (Error Checking and
Correction) could be turned on if parity DIMMS are used. The ECC will correct
one bit error and report two bit errors. Please be noted that the PEAK 6320A only
supports the SDRAM.

Installing DIMM
To install the DIMM , first make sure the two handles of the DIMM socket are in the
penposition, i.e. the handles stay outward. Slowly slide the DIMM modules
along the plastic guides in the both ends of the socket. Then press the DIMM
module down right into the socket, until a click is heard. That means the two
handles automatically locked the memory modules into the right position of the
DIMM socket as Figure 3-1 shows. To take away the memory module, just push the
both handles outward , the memory module will be ej ected by the mech anism in the
socket.

3-2 Cache Memory
Since the second level cache has been embedded in to the Pentium II CPU. You do
not have to take care of either SRAM chips or SRAM modu les. The built-in second
level cache in the Pentium II yields much higher performance than the external ones.
The cache size in the Pentium II CPU is either 256KB or 512KB. Normally, for
workstation and server applications, th e 256KB version is good enou gh. However,
if your system is for heavy duty applications, the 512kB version will help a lot.
Specifically for our Pentium II based SBC, the Pentium II has another version
provide much better data security if combined with the DRAM ECC, please check
with your vendor for various Pentium II models.
Figure 3-2 Memory Banks
The level 2 cache of the Peak 6320A is built in the Celeron/Pentium III current
Celerons have 128 KB on die L2 Cache which is very fast because it’s running at the
CPU speed. Future Celerons/Pentium III might be upgr aded to 256 KB L2 Cache.

3-3 Change CPU
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 CPU up to remove it from
the socket.

Place the new CPU on the middle of the socket, orienting its beveled corner to line up
with the socket's beveled corner. Make sure the pins of the CPU fit even ly to the
socket openings. Replace the handling bar to fasten the CPU to the socket. Be
sure to re-arrange the jumper setting for the correct external clock (66MHz or
100MHz) by (SW1.3) (SW1.4).
