Chapter 1 Hardware Configuration  
1.1 Introduction  
Advantech's PCA-6186 full-size CPU card is designed with Intel 845G  
chipset and supports socket 478 Pentium 4/Celeron processor (FSB 400/  
533MHz) up to 2.4GHz and above. In addition to high-speed processor,  
PCA-6186 supports up to 2GB DDR memory with 2 DIMM socket on  
board. It provides maximum computing power and productivity which is  
ideal for high-performance demanding application. Intel's 845G inte-  
grated VGA provides superior 3D performance with AGP 4X. Dual Intel  
82551/82562 10/100Base-T Ethernet controller or dual Intel 82540 10/  
100/1000Base-T Ethernet controller are available in PCA-6186 series.  
The high reliability and excellent performance provided by Intel Ethernet  
controller are crucial for various network applications. PCA-6186 also  
offers an exclusive feature of USB 2.0 and which provides high speed  
data transfer rate up to 480 Mb/sec. In addition to onboard two USB con-  
nectors, flexible I/O expension board allows customer to optimize their  
need for additional four USB port.  
A backup of CMOS data is stored in the Flash memory, which protects  
data even after a battery failure. Also included is a 255-level watchdog  
timer, which resets the CPU or generates an interrupt if a program cannot  
be executed normally. This enables reliable operation in unattended envi-  
ronments.  
The remote management interface enables the PCA-6186 to be managed  
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/  
SNMP System Manager..  
Note:

3.  
Fan status monitoring and alarm: To prevent system overheating  
and damage, the CPU fan can be monitored for speed and failure.  
The fan is set for its normal RPM range and alarm thresholds.  
Temperature monitoring and alert: To prevent system overheat-  
ing and damage, the CPU card supports processor thermal sensing  
and auto-protection.  
Voltage monitoring and alert: System voltage levels are moni-  
tored to ensure stable current flows to critical components. Voltage  
specifications will become even more critical for processors of the  
future. Thus monitoring will become ever more necessary to ensure  
proper system configuration and management.  
4.  
ATX soft power switch: Through the BIOS, the power button can  
be defined as the "Standby" (aka "Suspend" or "Sleep") button or as  
the "Soft-Off" button (see Section 3.7.8 Soft-off by PWR-BTN).  
Regardless of the setting, pushing the power button for more than 4  
seconds will enter the Soft-Off mode.  
5.  
6.  
7.  
8.  
Power-on by modem (requires modem): This allows a computer  
to be turned on remotely through an internal or external modem.  
Users can thus access information on their computers from any-  
where in the world.  
Power-on by LAN: This allows you to remotely power up your  
system through your network by sending a wake-up frame or sig-  
nal. With this feature, you can remotely upload/ download data to/  
from systems during off-peak hours.  
Message LED: Chassis LEDs now act as information providers.  
The way a particular LED illuminates indicates the stage the com-  
puter is in. A single glimpse provides useful information to the  
user.  
CMOS RAM backup: When BIOS CMOS setup has been com-  
pleted, data in the CMOS RAM is automatically backed up to the  
Flash ROM. This is particularly useful in industrial environments  
which may cause soft errors. Upon such an error occurring, BIOS  
will check the data, and automatically restore the original data for  
booting.

1.6 Safety Precautions  
Warning! Always completely disconnect the power cord  
from your chassis whenever you work with the  
hardware. Do not make connections while the  
power is on. Sensitive electronic components  
can be damaged by sudden power surges. Only  
experienced electronics personnel should open  
the PC chassis.  
Caution!  
Always ground yourself to remove any static  
charge before touching the CPU card. Modern  
electronic devices are very sensitive to static  
electric charges. As a safety precaution, use a  
grounding wrist strap at all times. Place all elec-  
tronic components on a static-dissipative sur-  
face or in a static-shielded bag when they are  
not in the chassis.  
Caution!  
The computer is provided with a battery-pow-  
ered Real-time Clock circuit. There is a danger  
of explosion if battery is incorrectly replaced.  
Replace only with same or equivalent type rec-  
ommended by the manufacturer. Discard used  
batteries according to manufacturer's instruc-  
tions.  
1.7 Jumper Settings  
This section provides instructions on how to configure your card by set-  
ting the jumpers. It also includes the card's default settings and your  
options for each jumper.  
1.7.1 How to set jumpers  
You configure your card to match the needs of your application by setting  
the jumpers. A jumper is a metal bridge that closes an electrical circuit. It  
consists of two metal pins and a small metal clip (often protected by a  
plastic cover) that slides over the pins to connect them. To “close” (or  
turn ON) a jumper, you connect the pins with the clip. To “open” (or turn

OFF) a jumper, you remove the clip. Sometimes a jumper consists of a set  
of three pins, labeled 1, 2, and 3. In this case you connect either pins 1  
and 2, or 2 and 3. A pair of needle-nose pliers may be useful when setting  
jumpers.  
1.7.2 CMOS clear (J1)  
The PCA-6186 CPU card contains a jumper that can erase CMOS data  
and reset the system BIOS information. Normally this jumper should be  
set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to 2-3  
closed for just a few seconds, and then move the jumper back to 1-2  
closed. This procedure will reset the CMOS to its default setting.

1.7.3 Watchdog timer output (J2)  
The PCA-6186 contains a watchdog timer that will reset the CPU or send  
a signal to IRQ11 in the event the CPU stops processing. This feature  
means the PCA-6186 will recover from a software failure or an EMI  
problem. The J2 jumper settings control the outcome of what the com-  
puter will do in the event the watchdog timer is tripped.

Note:  
The interrupt output of the watchdog timer is a  
low level signal. It will be held low until the  
watchdog timer is reset.  
1.8 System Memory  
The top-left edge of the PCA-6186 contains two sockets for 184-pin dual  
in-line memory modules (DIMMs). Both two sockets use 3.3 V unbuf-  
fered synchronous DRAMs (DDR SDRAM). DIMMs are available in  
capacities of 64, 128, 256, 512 MB, or 1 GB. The sockets can be filled in  
any combination with DIMMs of any size, giving your PCA-6186 single  
board computer between 64 MB and 2 GB of memory. Use the following  
table to calculate the total DRAM memory within your computer:

1.8.1 Sample calculation: DIMM memory capacity  
Suppose you install a 512 MB DIMM into your PCA-6186's socket 1 and  
a 512 MB DIMM into sockets 2. Your total system memory is 1 GB, cal-  
culated as follows:

1.9 Memory Installation Procedures  
To install DIMMs, first make sure the two handles of the DIMM socket  
are in the "open" position. i.e. The handles lean outward. Slowly slide the  
DIMM module along the plastic guides on both ends of the socket. Then  
press the DIMM module right down into the socket, until you hear a  
click. This is when the two handles have automatically locked the mem-  
ory module into the correct position of the DIMM socket. To remove the  
memory module, just push both handles outward, and the memory mod-  
ule will be ejected by the mechanism in the socket.  
1.10 Cache Memory  
Since the second-level (L2) cache has been embedded into the Intel®  
socket 478 Pentium® 4/Celeron™ processor, you do not have to take care  
of either SRAM chips or SRAM modules. The built-in second-level  
cache in the processor yields much higher performance than the external  
cache memories. The cache size in the Intel ® Pentium ® 4 processor is  
512 KB. In the Celeron CPU, the cache size is 128KB.

Connecting  
Peripherals  
This chapter tells how to connect  
peripherals, switches, and indicators to  
the PCA-6186 board.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 2 Connecting Peripherals  
2.1 Introduction  
You can access most of the connectors from the top of the board while it  
is installed in the chassis. If you have a number of cards installed or have  
a packed chasis, you may need to partially remove the card to make all  
the connections.  
2.2 Primary (CN1) and Secondary (CN2) IDE Connec-  
tors  
CN1  
CN2  
You can attach up to four IDE (Integrated Drive Electronics) drives to the  
PCA-6186’s built-in controller. The primary (CN1) and secondary (CN2)  
connectors can each accommodate two drives.  
Wire number 1 on the cable is red or blue and the other wires are gray.  
Connect one end to connector CN1 or CN2 on the CPU card. Make sure  
that the red/blue wire corresponds to pin 1 on the connector (in the upper  
right hand corner). See Chapter 1 for help finding the connector.  
Unlike floppy drives, IDE hard drives can connect in either position on  
the cable. If you install two drives to a single connector, you will need to  
set one as the master and the other as the slave. You do this by setting the  
jumpers on the drives. If you use just one drive per connector, you should  
set each drive as the master. See the documentation that came with your  
drive for more information.  
Connect the first hard drive to the other end of the cable. Wire 1 on the  
cable should also connect to pin 1 on the hard drive connector, which is  
labeled on the drive circuit board. Check the documentation that came  
with the drive for more information.  
Connect the second hard drive to the remaining connector (CN2 or CN1),  
in the same way as described above.

2.3 Floppy Drive Connector (CN3)  
CN3  
You can attach up to two floppy disk drives to the PCA-6186's onboard  
controller. You can use 3.5" (720 KB, 1.44 MB) drives.  
The card comes with a 34-pin daisy-chain drive connector cable. On one  
end of the cable is a 34-pin flat-cable connector. On the other end are two  
sets of 34-pin flat-cable connector (usually used for 3.5" drives). The set  
on the end (after the twist in the cable) connects to the A: floppy drive.  
The set in the middle connects to the B: floppy drive.  
2.4 Parallel Port (CN4)  
CN4  
The parallel port is normally used to connect the CPU card to a printer.  
The PCA-6186 includes an onboard parallel port, accessed through a 26-  
pin flat-cable connector, CN4. The card comes with an adapter cable  
which lets you use a traditional DB-25 connector. The cable has a 26-pin  
connector on one end and a DB-25 connector on the other, mounted on a  
retaining bracket. The bracket installs at the end of an empty slot in your  
chassis, giving you access to the connector.  
To install the bracket, find an empty slot in your chassis. Unscrew the  
plate that covers the end of the slot. Screw in the bracket in place of the  
plate. Next, attach the flat-cable connector to CN4 on the CPU card. Wire  
1 of the cable is red or blue, and the other wires are gray. Make sure that  
wire 1 corresponds to pin 1 of CN4. Pin 1 is on the upper right side of  
CN4.

CN34)  
CN8 and CN34  
The PCA-6186 is equipped with one or two high-performance 32-bit  
PCI-bus Ethernet interfaces, which are fully compliant with IEEE 802.3/u  
10/100 Mbps CSMA/CD standards. Also, PCA-6186 provides the option  
of supporting single or dual 10/10/1000 Mbps Ethernet LANs. They are  
supported by all major network operating systems. The RJ-45 jacks on  
the rear plate provide convenient 10/100/1000 Base-T RJ-45 operation. If  
users use dual LANs, the second LAN port, CN34, is located at top slot of  
the I/O expension ports.  
2.8 Serial Ports (CN9: COM1; CN10: COM2)  
CN9 and CN10  
The PCA-6186 offers two serial ports, CN9 as COM1 and CN10 as  
COM2. These ports can connect to serial devices, such as a mouse or a  
printer, or to a communications network.  
The IRQ and address ranges for both ports are fixed. However, if you  
want to disable the port or change these parameters later, you can do this  
in the system BIOS setup.  
Different devices implement the RS-232 standard in different ways. If  
you are having problems with a serial device, be sure to check the pin  
assignments for the connector.

Chapter 3 Award BIOS Setup  
3.1 Introduction  
Award’s BIOS ROM has a built-in setup program that allows users to  
modify the basic system configuration. This type of information is stored  
in battery-backed memory (CMOS RAM) so that it retains the setup  
information when the power is turned off.  
3.2 Entering Setup  
Turn on the computer and check for the “patch code”. If there is a number  
assigned to the patch code, it means that the BIOS supports your CPU.  
If there is no number assigned to the patch code, please contact Advan-  
tech’s applications engineer to obtain an up-to-date patch code file. This  
will ensure that your CPU’s system status is valid.  
After ensuring that you have a number assigned to the patch code, press  
<Del> to allow you to enter the setup.

3.3.1 CMOS RAM backup  
The CMOS RAM is powered by an onboard button cell battery.  
When BIOS CMOS Setup has been completed, CMOS RAM data is auto-  
matically backed up to Flash ROM. If conditions in a harsh industrial  
enviroment cause a soft error, BIOS will recheck the data and automati-  
cally restore the original data for booting.

Before you begin, it is important to note that most display drivers need to  
have the relevant software application already installed in the system  
prior to installing the enhanced display drivers. In addition, many of the  
installation procedures assume that you are familiar with both the rele-  
vant software applications and operating system commands. Review the  
relevant operating system commands and the pertinent sections of your  
application software’s user’s manual before performing the installation.

Chapter 5 AGP VGA Setup  
5.1 Introduction  
As quoted from "Intel® 845G chipset Graphics Chipset Controller Hub  
(GMCH) Rev. 1.0 May 2002.”:  
The Intel® 845G Graphics Memory Controller Hub (the 845G GMCH) is  
Intel’s first memory controller hub with integrated graphics for the Intel  
Pentium® 4 processor. The 845G GMCH, with its new architecture  
graphics engine, delivers not only high 2D/3D graphics performance, but  
also provides efficient, high bandwidth communication channels connect-  
ing the processor, the memory, the I/O subsystem, and other components  
together to deliver a stable mainstream desktop platform solution. The  
features include:  
• Built-in 2D/3D AGP VGA controller.  
• Integrated 350MHz RAMDAC that can directly drive a progressive  
scan analog monitor up to a resolution of 2048x1536 at 60MHz  
• Up to 1600 x 1200 x 32 resolution at 85 Hz refresh.  
• H/W motion compensation assistance for s/w MPEG 2 decoding.  
• Software DVD at 30 fps Full Screen.  
5.2 Dynamic Video Memory Technology  
The following is quoted from "Intel® 845G/845GL Chipset Dynamic  
Video Memory Technology" Rev. 1.2 June 2002”:  
Dynamic Video Memory Technology (DVMT) is an enhancement of the  
UMA concept, wherein the optimum amount of memory is allocated for  
balanced graphics and system performance, through Direct AGP known  
as Non-Local Video Memory (NLVM), and a highly efficient memory  
utilization scheme. DVMT ensures the most efficient use of available  
memory ñ regardless of frame buffer or main memory sizing ñ for maxi-  
mum 2D/3D Graphics performance. DVMT dynamically responds to  
system requirements, and applications demands, by allocating the proper  
amount of display, texturing and buffer memory after the operating sys-  
tem has booted. For example, a 3D application when launched may  
require more vertex buffer memory to enhance the complexity of objects,  
or more texture memory to enhance the richness of the 3D environment.  
The operating system views the integrated graphics driver as an applica-

tion, which uses Direct AGP to request allocation of additional memory  
for 3D applications, and returns the memory to the operating system  
when no longer required.  
The Intel Extreme Graphics Driver determines the size of the pre-allo-  
cated memory needed and will make additional Non-Local Video Mem-  
ory requests to achieve the amount needed for the display and application  
requirement. The video memory size in the Intel(R) 845G/GL chipset  
varies and is determined using several factors. The key factors are system  
resources and system activity. The maximum video memory is up to  
64MB SDRAM

• Users no longer have to manually enable DMA transfers for each  
ATA and/or ATAPI peripheral devices.  
• Each ATA channel has independent device timings/transfers which  
allows PIO-only and DMA-capable devices to share the same  
ATA controller cable, where one is the master and the other the  
slave, without restricting transfer mode to PIO-only for both  
devices.  
• Technical details of the ATA subsystem can be viewed via use of the  
application.  
• Drivers are optimized.

9.4 Using the OBS Hardware Doctor Utility  
After completing the setup, all the OBS functions are permanently  
enabled. When a monitored reading exceeds safe limits, a warning mes-  
sage will be displayed and an error beep tone will activate to attract your  
attention.  
OBS Hardware Doctor will show an icon on the right side of the bottom  
window bar. This icon is the "Terminate and Stay Resident" (TSR) icon.  
It will permanently remain in the bottom window bar, and will activate  
warning signals when triggered by the onboard security  
system.  
You can view or change values for various OBS settings by running this  
utility:

Programming the  
Watchdog Timer  
The PCA-6186 is equipped with a  
watchdog timer that resets the CPU or  
generates an interrupt if processing  
comes to a standstill for any reason.  
This feature ensures system reliability  
in industrial standalone or unmanned  
environments.

Appendix A Programming the watchdog  
timer  
A.1 Programming the Watchdog Timer  
The PCA-6186's watchdog timer can be used to monitor system software  
operation and take corrective action if the software fails to function after  
the programmed period. This section describes the operation of the  
watchdog timer and how to program it.  
A.1.1 Watchdog timer overview  
The watchdog timer is built-in the super I/O controller W83627HF. It  
provides the following functions for user programming:  
• Can be enabled and disabled by user's program.  
• Timer can be set from 1 to 255 seconds or 1 to 255 minutes.  
• Generates an interrupt or resets signal if the software fails to reset the  
timer after time-out.  
A.1.2 Reset/ Interrupt selection  
The J2 jumper is used to select reset or interrupt (IRQ 11) in the event the  
watchdog timer is tripped. See Chapter 1 for detailed jumper settings.

A.1.3 Programming the Watchdog Timer  
The I/O port address of the watchdog timer is 2E(hex) and 2F(hex).  
2E (hex) is the address port. 2F(hex) is the data port.  
You must first assign the address of register by writing address value  
into address port 2E(hex), then write/read data to/from the assigned  
register through data port 2F (hex).

rupt or reset signal. Writing  
a new value to this register  
can reset the timer to count  
with the new value.
