1.0.2 Product warranty  
Advantech warrants to you, the original purchaser, that each of its prod-  
ucts will be free from defects in materials and workmanship for two years  
from the date of purchase.  
This warranty does not apply to any products which have been repaired or  
altered by persons other than repair personnel authorized by Advantech,  
or which have been subject to misuse, abuse, accident or improper instal-  
lation. Advantech assumes no liability under the terms of this warranty as  
a consequence of such events.  
If an Advantech product is defective, it will be repaired or replaced at no  
charge during the warranty period. For out-of-warranty repairs, you will  
be billed according to the cost of replacement materials, service time and  
freight. Please consult your dealer for more details.  
If you think you have a defective product, follow these steps:  
Step 1. Collect all the information about the problem encountered. (For  
example, type of PC, CPU speed, Advantech products used,  
other hardware and software used, etc.) Note anything abnormal  
and list any on-screen messages you get when the problem  
occurs.  
Step 2. Call your dealer and describe the problem. Please have your man-  
ual, product, and any helpful information readily available.  
Step 3. If your product is diagnosed as defective, obtain an RMA (return  
material authorization) number from your dealer. This allows us  
to process your return more quickly.  
Step 4. Carefully pack the defective product, a fully-completed Repair  
and Replacement Order Card and a photocopy proof of purchase  
date (such as your sales receipt) in a shippable container. A prod-  
uct returned without proof of the purchase date is not eligible for  
warranty service.  
Step 5. Write the RMA number visibly on the outside of the package and  
ship it prepaid to your dealer.

Chapter 1 Hardware Configuration  
1.1 Introduction  
The PCA-6187 Series all-in-one industrial grade single board computer is  
a high performance and full-featured computing engine. It follows the  
PICMG 1.0 specification and meets most requirements for industrial  
applications.  
The PCA-6187 uses Intel's 865G chipset to support Intel's Socket 478  
Pentium 4 and Celeron processor with 800/533/400 MHz front side bus.  
The dual channel DDR 400 SDRAM interface provides bottle neck free  
memory bandwidth up to 6.4GB/s. In addition to the two EIDE interfaces  
(up to four devices), it features a high performance serial ATA interface  
(up to 150MB/s) which eases cabling to hard drives in industrial chassis  
with thin and long cables. Other features include chipset built-in high per-  
formance VGA interface, dual Giga-bit Ethernet ports, dual channel Ultra  
160 SCSI interface, six USB 2.0 ports (up to 480 Mbps), and other stan-  
dard PC functions like two RS-232 serial ports, one enhanced parallel  
port and floppy disk interface.  
The PCA-6187 Series offers several impressive industrial features such  
as: CMOS data backup, which is stored in the Flash memory, which pro-  
tects data even after battery failure. Also included is a 256-level watch-  
dog timer, which resets the CPU if a program cannot be executed  
normally. This enables reliable operation in unattended environments.  
The remote management interface enables the PCA-6187 to be managed  
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/  
SNMP System Manager.  
Note:  
Some of the features mentioned above are not  
available with all models. For more information  
about the specifications of a particular model,  
see Table 1.1 : Comparison table and Section  
1.3: Specifications.

1.2 Features  
1.  
High performance: The PCA-6187 uses Intel 865G chipset which  
offers high-bandwidth interfaces such as dual-channel DDR400  
main memory, 800 MHz system bus, integrated graphics controller  
with Intel® Extreme Graphics 2 Technology, Intel® Communica-  
tion Streaming Architecture featuring a Dedicated Network Bus  
(DNB) interface for Gigabit Ethernet (GbE) and Hi-Speed USB 2.0  
connectivity to ensure the flexibility and performance you expect.  
2.  
3.  
Remote management: System healthy status including CPU fan,  
CPU temperature and system voltages levels are monitored to  
ensure stable operation. A remote monitoring interface is reserved  
for remote management through Ethernet by using Advantech's  
SNMP-1000 system management module.  
BIOS CMOS backup and restore: When BIOS CMOS setup has  
been completed, data in the CMOS RAM is automatically backed  
up to the Flash ROM. This is particularly useful in harsh environ-  
ments which may cause setup data loss such as battery failure.  
Upon such an error occurring, BIOS will check the data, and auto-  
matically restore the original data for booting.  
4.  
Supports Hyper-Threading : This allows a single HT-enabled  
Pentium 4 processor to process two threads simultaneously. By  
building two logical processors into a single physical processor, the  
performance and utilization of the processor resource will both  
increase. Users can obtain a higher CPU performance while Hyper-  
Threading is enabled.  
1.3 Specifications

1.7 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 single board com-  
puter. Modern electronic devices are very sen-  
sitive to static electric charges. As a safety  
precaution, use a grounding wrist strap at all  
times. Place all electronic components on a  
static-dissipative surface 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.  
Notice: Before install your PCA-6187 into a chassis, make sure that all components  
on both sides of the CPU card do not touch any metal parts, especially the chassis  
wall and add-on card at the adjacent slot.

1.8 Jumper Settings  
This section provides instructions on how to configure your single board  
computer by setting the jumpers. It also includes the single board com-  
puter's default settings and your options for each jumper.  
1.8.1 How to set jumpers  
You can configure your single board computer 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.  
1.8.2 CMOS clear (J1)  
The PCA-6187 single board computer contains a jumper that can erase  
CMOS data and reset the system BIOS information. Normally this  
jumper should be set with pins 1-2 open. If you want to reset the CMOS  
data, set J1 to 1-2 closed for just a few seconds, and then move the jumper  
back to 1-2 open. This procedure will reset the CMOS to its default set-  
ting.  
Table 1.4: CMOS (J1)

1.8.3 Watchdog timer output (J2)  
The PCA-6187 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-6187 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.  
1.9 System Memory  
The PCA-6187 has four sockets for 184-pin dual inline memory modules  
(DIMMs) in two separated memory channels. It can operate with single  
channel or dual channel modules. We recommend to use dual channel  
mode to provide optimized performance.  
All these sockets use 2.5 V unbuffered double data rate synchronous  
DRAMs (DDR SDRAM). They are available in capacities of 128, 256,  
512 and 1024 MB. The sockets can be filled in any combination with  
DIMMs of any size, giving a total memory size between 128 MB and 4  
GB.  
Note: System resources such as PCI and AGP require physical  
memory address locations that reduce available memory  
addresses above 3GB. This may result in less than 4GB of mem-  
ory being available to the operating system and applications.

1.9.1 CPU FSB and memory speed  
The PCA-6187 can accept DDR SDRAM memory chips without parity.  
Also note: The PCA-6187 accepts PC2100 (DDR266), PC2700 (DDR  
333) and PC3200 (DDR 400) DDR SDRAM, depending on the CPU  
front side bus frequency (FSB). Please refer below table for the relation-  
ship between the CPU FSB and memory speed.

The PCA-6187 does not support ECC (error checking and correction).  
Memory modules with 9 SDRAM chips/side support ECC; modules with  
8 chips/side do not support ECC.  
1.9.2 Dual channel configuration  
The four DIMM sockets are arranged in two channels: DIMM1 &  
DIMM2 in channel A; DIMM3 & DIMM4 in channel B. To enable dual  
channel operation, please install a matched pair of DIMMs in DIMM1 &  
DIMM3 (green sockets). If additional memory is to be used, another  
matched pair of DIMMs have to be installed in DIMM2 & DIMM4 (pur-  
ple sockets).  
"Matched pair of DIMMs" means: same in speed (DDR266, DDR333,  
DDR400), same in size (128MB, 256MB, 512MB or 1GB), same in chip  
density (128 Mb, 256Mb or 512Mb and same in CSA latency. Any other  
memory configuration will result in single channel memory operation.

1.10 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.  
1.11 Processor Installation  
The CPU on the board must have a fan or heat sink attached, to prevent  
overheating.  
Warning: Without a fan or heat sink, the CPU will over-heat and cause  
damage to both the CPU and the single board computer. To install a CPU,  
first turn off your system and remove its cover. Locate the processor  
socket 478.  
1. Make sure the socket 478 lever is in the upright position. To raise the  
lever, pull it out to the side a little and raise it as far as it will go.  
2. Place the CPU in the empty socket. Follow the instructions that came  
with the CPU. If you have no instructions, complete the following proce-  
dure. Carefully align the CPU so it is parallel to the socket and the  
notches on the corners of the CPU correspond with the notches on the  
inside of the socket. Gently slide the CPU in. It should insert easily. If it  
does not insert easily, pull the lever up a little bit more.  
3. Press the lever down. The plate will slide forward. You will feel some  
resistance as the pressure starts to secure the CPU in the socket. This is  
normal and will not damage the CPU. When the CPU is installed, the  
lever should snap into place at the side of the socket.  
Note : The CPUs made with 0.18 micro-meter process technology  
("Willamette") cannot be supported by PCA-6187.

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 chassis, you may need to partially remove the card to make all  
the connections.  
2.2 1st & 2nd (CN1, CN2) IDE Connectors  
CN1  
CN2  
You can attach up to four IDE (Integrated Drive Electronics) drives to the  
PCA-6187’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 single board computer.  
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 connec-  
tor.  
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-6187's on board  
controller. You can use 3.5" (720 KB, 1.44 MB) drives.  
The single board computer comes with a 34-pin daisy-chain drive con-  
nector 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 single board computer to  
a printer. The PCA-6187 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.  
The parallel port is designated as LPT1, and can be disabled or changed  
to LPT2 or LPT3 in the system BIOS setup.  
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

supported by all major network operating systems and is 100% Novell  
NE-2000 compatible. An onboard RJ-45 jack provides convenient 10/  
100Base-T or 10/100/1000Base-T RJ-45 operation.  
2.8 Serial Ports (COM1 : CN9; COM2 : CN10 )  
The PCA-6187 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.  
3.1.1 CMOS RAM Auto-backup and Restore  
The CMOS RAM is powered by an onboard button cell battery. When  
you finish BIOS setup, the data in CMOS RAM will be automatically  
backed up to Flash ROM. If operation in harsh industrial environment  
cause a soft error, BIOS will recheck the data in CMOS RAM and auto-  
matically restore the original data in Flash ROM to CMOS RAM for  
booting.  
Note:  
If you intend to change the CMOS setting with-  
out restoring the previous backup, you have to  
click on "DEL" within two seconds of the  
"CMOS checksum error..." display screen mes-  
sage appearing. Then enter the "Setup" screen  
to modify the data. If the "CMOS checksum  
error..."message appears again and again,  
please check to see if you need to replace the  
battery in your system.

Chapter 5 VGA Setup  
5.1 Introduction  
The PCA-6187 has VGA onboard, you need to install the VGA driver to  
enable the function.  
The Intel® 865G Graphics Memory Controller Hub (the 865G GMCH)  
provides an integrated graphics accelerator delivering cost competitive  
3D, 2D, and video capabilities. The GMCH contains an extensive set of  
instructions for 3D operations, BLT and Stretch BLT operations, motion  
compensation, overlay, and display control. The 865G GMCH’s video  
engines support video conferencing and other video applications. The  
GMCH does not support a dedicated local graphics memory interface; it  
may only be used in a UMA configuration. The features include:  
• Built-in 2D/3D VGA controller.  
• Use Intel® Extreme Graphics Architecture  
• Integrated 350MHz RAMDAC that can directly drive a progressive  
scan analog monitor up to a resolution of 2048x1536 at 75Hz  
• Maximum 3D resolution supported : 1600 x 1200 x 32 @ 85Hz.  
• 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® 865G Chipset Dynamic Video  
Memory Technology", document number : 253144-001 :  
The method of memory allocation where the Operating System, Applica-  
tion and Graphics Memory come from a unified System Memory pool  
known as Unified Memory Architecture (UMA).  
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, or NLVM), and a highly efficient memory  
utilization scheme. DVMT ensures the most efficient use of available  
memory – regardless of frame buffer or main memory sizing – for maxi-  
mum 2D/3D graphics performance.  
PCA-6187 User’s Manual  
52  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
DVMT dynamically responds to system requirements, and application  
demands, by allocating the proper amount of display, texturing and buffer  
memory after the operating system has booted. For example, a 3D appli-  
cation 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 inte-  
grated graphics driver as an application, which uses Direct AGP to  
request allocation of additional memory for 3D applications, and returns  
the memory to the operating system (OS) 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® 865G 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

Chapter 7 SCSI Setup & Configuration  
7.1 Introduction  
The PCA-6187 is equipped with an Adaptec AIC-7899 single-chip PCI-  
to-SCSI host adapter which provides a dual channel Ultra 160 multi-  
tasking interface between your computer.s PCI bus and SCSI devices  
(disk drives, CD-ROM drives, scanners, tape backups, removable media  
drives, etc.). Ultra 160 is a new generation of SCSI technology that  
expands SCSI performance from 80 MBytes/sec to 160 MBytes/ sec. Up  
to a total of 15 SCSI devices can be connected to each of the SCSI con-  
nectors.  
The AIC-7899 combines this Ultra 160 SCSI technology with Adaptec.s  
SpeedFlex. technology. SpeedFlex allows the Adaptec SCSI card to be  
backwards compatible with previous generations of SCSI products, while  
allowing newer Ultra 160 SCSI devices to operate at the higher 160  
MBytes/sec rate.  
There are 3 SCSI connectors on the CPU card: CN50 and CN51 for Ultra  
160 devices, and CN52 for 50-pin SCSI devices. You can use Ultra 160  
and Ultra wide devices simultaneously without compromising the perfor-  
mance.  
If you need to configure the SCSI, the onboard SCSI Select configuration  
utility allows you to change host adapter settings without opening the  
computer or handling the board. The SCSI Select utility also contains a  
utility to low-level format and verifies the disk media on your hard disk  
drives.  
Note:  
If any peripheral is running at SE mode, the  
Ultra 160 SCSI segment will run at speeds up to  
40 MBytes/sec only instead of 160 MBytes/sec.

7.2 Understanding SCSI  
SCSI (pronounced .scuzzy.) stands for Small Computer Systems Inter-  
face. SCSI is an industry standard computer interface for connecting  
SCSI devices to a common SCSI bus.  
A SCSI bus is an electrical pathway that consists of a SCSI interface  
installed in a computer and one or more SCSI devices. SCSI cables are  
used to connect the devices to the SCSI interface. For the SCSI bus to  
function properly, a unique SCSI ID must be assigned to the SCSI inter-  
face and each SCSI device connected to it, and the SCSI bus must be  
properly terminated.  
7.3 SCSI IDs  
Each device attached to the SCSI bus, as well as the SCSI controller  
itself, must be assigned a unique SCSI ID number from 0 to 15. A SCSI  
ID uniquely identifies each SCSI device on the SCSI bus and determines  
priority when two or more devices are trying to use the SCSI bus at the  
same time.  
Refer o the device.s documentation to set the SCSI ID. Here are some  
general guidelines for SCSI IDs:  
• For internal SCSI devices, the SCSI ID usually is set by configuring a  
jumper on the device.  
• For external SCSI devices, the SCSI ID usually is set with a switch on  
the back of the device.  
• SCSI ID numbers don.t have to sequential, as long as the SCSI control-  
ler and each device has a different number.  
• For example, you can have an internal SCSI device with ID 0, and an  
external SCSI device with ID 6.  
• SCSI ID 7 has the highest priority on the SCSI bus. The priority of the  
remaining IDs, in descending order, is 6 to 0, then 15 to 8.  
• The on-boards SCSI interface is preset to SCSI ID 7 and should not be  
changed. This gives it the highest priority on the SCSI bus.  
• Most internal SCSI hard disk drives come from the factory pre-set to  
SCSI ID 0.  
• If you have 8-bit (or Narrow) SCSI devices, they must use SCSI IDs 0,  
1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first SCSI hard  
disk drive.  
65  
Chapter7

• If you are booting your computer from a SCSI hard disk drive con-  
nected to the SCSI bus, the Boot SCSI ID setting in the SCSISelect  
utility must correspond to the SCSI ID of the device from which you  
are booting. By default, the Boot SCSI ID is set to 0. We recommend  
that you do not change this setting.  
• In Windows 95/98, you can use the Device Manager to determine  
which SCSI ID is assigned to each installed SCSI device.  
7.4 Terminating the SCSI Bus  
To ensure reliable communication on the SCSI bus, the ends of the SCSI  
bus must be properly terminated. This is accomplished when the device at  
the end of the each cable, or the end of the cable itself, has a terminator  
installed (or enabled). Terminators must be removed, or termination must  
be disabled, on devices between the ends of each cable.  
Since the method for terminating a SCSI device can vary widely, refer to  
the device.s documentation for instructions on how to enable or disable  
termination. Here are some general guidelines for termination:  
• Internal Ultra 160 and Ultra 2 SCSI devices come from the factory with  
termination disabled and cannot be changed. Proper termination for  
internal Ultra 160 and Ultra2 SCSI devices is provided by a 68-pin  
Internal LVD (low voltage differential) SCSI cable, which has a built-  
in terminator at its end.  
• Termination on non-Ultra 160 and Ultra2 internal SCSI devices usually  
is controlled by manually setting a jumper or a switch on the device, or  
by physically removing or installing one or more resistor modules on  
the device.  
• Termination on most external SCSI devices is controlled by installing  
or removing a SCSI terminator. However, termination on some exter-  
nal SCSI devices is enable or disabled by setting a switched on the  
back of the SCSI device.  
The last external Ultra160 or Ultra2 SCSI device must be terminated with  
an LVD/SE (low voltage differential/single ended) terminator plug to  
ensure that the device will operate at its maximum speed. If you use a dif-  
ferent kind of terminator plug, the data I/O rate will decrease.  
By default, termination on the SCSI controller itself is set to Automatic  
(the preferred method). We recommend that you do not change this  
default setting.

SCSI Bus Interface Definitions  
• Host Adapter SCSI ID-(Default: 7) Sets the SCSI ID for the SCSI  
controller. The Adaptec SCSI controller AIC-7899 is set at 7, which  
gives the highest priority on the SCSI bus. We recommend that you do  
not change this setting.  
• SCSI Parity Checking-(Default: Enabled) When set to Enabled, veri-  
fies the accuracy of data transfer on the SCSI bus. Leave this setting  
enabled unless any SCSI device does not support SCSI parity.  
• Host Adapter SCSI Termination-(Default: Automatic) Determines  
the termination setting for the SCSI card. The default setting for both  
the LVD/SE (low voltage differential/single ended) connectors and SE  
connectors is Automatic, which allows the SCSI card to adjust the ter-  
mination as needed depending on the configuration of the connected  
SCSI devices. We recommend that you do not change these settings.  
Boot Device Options  
• Boot SCSI ID-(Default: 0) Specifies the SCSI ID of your boot  
device. We recommend that you don’t change the default setting.

Unit Command is sent to the SCSI device at bootup.  
The following three options have no effect if the SCSI Card BIOS is dis-  
abled. (The SCSI Cards BIOS is normally enabled by default.)  
• Enable Write Back Cache-(Default: N/C) Can be used to enable or  
disable the write-back cache on SCSI disk drives connected to the host  
adapter. Leave this option at its default setting of N/C (no change),  
which usually allow for optimum drive performance.  
• BIOS Multiple LUN Support-(Default: No) Leave this setting at No if  
the device does not have multiple Logical Unit Numbers (LUNs.)  
When set to Yes, the SCSI card BIOS provides boot support for a SCSI  
device with multiple LUNs (for example, a CD jukebox. device in  
which multiple CDs can be accessed simultaneously.)  
• Include in BIOS Scan-(Default: Yes) When set to Yes, the SCSI card  
BIOS includes the device as part of its BIOS scan at bootup.

Windows 95/98.  
• Verbose/Silent Mode-(Default: Verbose) When set to Verbose, the  
SCSI card BIOS displays the host adapter model on the screen during  
system buildup. When set to Silent, the message is not displayed dur-  
ing bootup.  
• Host Adapter BIOS (Configuration Utility Reserves BIOS Space)-  
(Default: Enabled) Enables or disables the SCSI card BIOS.  
• Leave at Enabled to allow the SCSI card BIOS to scan and initialize all  
SCSI devices.  
• Set to Disabled: Not scan if the devices on the SCSI bus (for example,  
CD-ROM drives) are controlled by software drivers and do not need  
the BIOS, and you do not want the BIOS to scan the SCSI bus.  
• Set to Disabled: Scan Bus if you do not need the BIOS, but you want it  
to scan the SCSI devices on the bus and you need to spin up the  
devices.  
The following four options have no effect when the SCSI Card BIOS is  
disabled. (The SCSI Card BIOS is normally enabled by default.)  
• Domain Validation.(Default: Enabled) Determines the optimal trans-  
fer rate for each device on the SCSI bus and sets transfer rates accord-  
ingly. Displays the resulting data transfer rate.

maintain your system's stability and durability. The PCA-6187 can moni-  
tor 5 sets of system positive voltages, 2 sets of system negative voltages,  
CPU cooling fan speed, and CPU temperature. The positive system volt-  
age sets which can be monitored include:  
• CPU core voltage: 1.3 V ~ 3.3 V, according to Intel specifications.  
• Transmission voltage from CPU to chipset: typically 1.8 V.  
• Chipset voltage: typically 3.3 V.  
• Main voltage: +5 V, +12 V.  
The negative system voltage sets which can be monitored include:  
• Main voltage: -5 V, -12 V.

Programming the  
Watchdog Timer  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix A Programming the watchdog  
A.1 Programming the Watchdog Timer  
The PCA-6187'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.  
Note:  
The interrupt output of the watchdog timer is a low  
level signal. It will be held low until the watchdog timer  
is reset.  
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).

a new value to this register  
can reset the timer to count  
with the new value.
