Quick Installation Guide
Utility CD
PFM-541I
Note:
The PFM-541I WiTAS series include the full cable kit because the
special cables can be used in rigid environment.
Because of the weight of the heatsink and the mounting design of the
heatsink, we strongly suggest you to review the system design:
- Make sure the vibration of the system will not impact the reliability of
board.
- If the TF-PFM-541IW2 has to be applied in severely vibrational
operating condition, the system level thermal solution will be an
alternative to minimize the vibration effect since the heatsink is installed
on the chipset.
If any of these items should be missing or damaged, please
contact your distributor or sales representative immediately.

PC/104 CPU Module PFM-541I
2.1 Safety Precautions
Always completely disconnect the power cord
from your board whenever you are working on
it. Do not make connections while the power is
on, because a sudden rush of power can
damage sensitive electronic components.
Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. 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

2.7 Setting Jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. 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”
a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

A pair of needle-nose pliers may be helpful when working with
jumpers. If you have any doubts about the best hardware
configuration for your application, contact your local distributor or
sales representative before you make any change. Generally, you
simply need a standard cable to make most connections.

3.1 System Test and Initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors. Non-fatal error messages
usually appear on the screen along with the following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue the boot
up sequence.
System configuration verification
These routines check the current system configuration against the
values stored in the CMOS memory. If they do not match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The PFM-541I CMOS memory has an integral lithium battery
backup for data retention. However, you will need to replace the
complete unit when it finally runs down.

to modify the basic system configuration. This type of information is
stored in battery-backed CMOS RAM so that it retains the Setup
information when the power is turned off.
Entering Setup
Power on the computer and press <Del> immediately. This will
allow you to enter Setup.
Standard CMOS Features
Use this menu for basic system configuration. (Date, t ime, IDE,
etc.)
Advanced BIOS Features
Use this menu to set the advanced features available on your
system.
Advanced Chipset Features
Use this menu to change the values in the chipset registers and
optimize your system performance.
Integrated Peripherals
Use this menu to specify your settings for integrated peripherals.
(Primary slave, secondary slave, keyboard, mouse etc.)

system.
Frequency/Voltage Control
Use this menu to specify your settings for auto detect DIMM/PCI
clock and spread spectrum.
Load Fail-Safe Defaults
Use this menu to load the BIOS default values for the
minimal/stable performance for your system to operate.
Load Optimized Defaults
Use this menu to load the BIOS default values that are factory

4.1 Software Drivers
This chapter describes the operation and installation of the display
drivers supplied on the Supporting CD-ROM that are shipped with
your product. The onboard VGA adapter is based on the AMD LX
VGA Flat Panel/CRT controller. This controller offers a large set of
extended functions and higher resolutions. The purpose of the
enclosed software drivers is to take advantage of the extended
features of the AMD LX VGA Flat Panel/CRT controller.
Hardware Configuration
Some of the high-resolution drivers provided in this package will
work only in certain system configurations. If a driver does not
display correctly, try the following:
1. Change the display controller to CRT-only mode, rather than flat
panel or simultaneous display mode. Some high-resolution
drivers will display correctly only in CRT mode.
2. If a high-resolution mode does not support your system, try to
use a lower-resolution mode. For example, 1024 x 768 mode will
not work on some systems, but 800 x 600 mode supports the
most.

4.2 Necessary to Know
The instructions in this manual assume that you understand
elementary concepts of MS-DOS and the IBM Personal Computer.
Before you attempt to install any driver from the Supporting
CD-ROM, you should:
Know how to copy files from a CD-ROM to a directory on the
hard disk
Understand the MS-DOS directory structure
If you are uncertain about any of these concepts, please refer
to the DOS or OS/2 user reference guides for more
information before you proceed with the installation.
Before you begin
The Supporting CD-ROM contains different drivers for
corresponding Windows OS, please choose the specific driver for
your Windows OS.

Appendix A Programming the Watchdog Timer A-1
PC/104 CPU Module PFM-541I
A.1 Programming
PFM-541I utilizes SCH3114-NU chipset as its watchdog timer
controller.
The SCH311X WDT ( W atch Dog Timer ) has a programmable
time-out ranging from 1 to 255 minutes with one minute resolution,
or 1 to 255 second resolution. The unit of the WDT timeout value
are selected via bit[7] of the WDT_TIMEOUT register. The WDT
time-out value is set through the WDT_VAL Runtime register.
Setting The WDT_VAL re gister to 0x00 disables the WDT function
(this is its power on default).
Setting the WDT_VAL to any other non-zero value will cause the
WDT to reload and begin counting down from the value loaded.
When the WDT count value reaches zero the counter sto ps and
sets the Watchdog time-out status bit in the WDT_CTRL Runtime
register. Note: Regardl ess of the current state of the WDT, the WDT
time-out status bit can be directly set or cleared by the Host CPU.
The related register for configuring WDT is list as follows:
