PC/104 CPU Module PFM-535S
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

2.6 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.

BIOS Setup
Chapter 3 AMI BIOS Setup 3-1
PC/104 CPU Module PFM-535S
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-535S 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.
Chapter 3 AMI BIOS Setup 3-2
PC/104 CPU Module PFM-535S
3.2 AMI BIOS Setup
AMIs 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 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.
Main
Use this menu for basic system configuration. (Processor, System
memory, Date, etc.)
Advanced
Use this menu to set the advanced features available on your
system.
PCIPnP
This entry appears if your system supports PnP/PCI.
Boot
This menu shows boot setting configurations.
Security
Use this menu to set the password for system security.
Chipset
Use this menu to set Northbridge and Southbridge configuration.
Exit
Use this menu to load or save CMOS value and exit setup.
You can refer to the “ BIOS Item Description ” option in the CD
auto-run menu for the meaning of each setting in this chapter.

Programming the
Watchdog Timer
Appendix
Appendix A Programming the Watchdog Timer A-1
PC/104 CPU Module PFM-535S
A.1 Programming
There are two watchdog timers in Vortex86SX/DX CPU. One is
compatible with M6117D watchdog timer and the other is new. The
M6117D compatible watchdog timer is called WDT0 and new one is
called WDT1.
WDT0
To access WDT0 registers, programmer can use index port 22H
and data port 23H. The watchdog timer uses 32.768 kHz frequency
source to count a 24-bit counter so the time range is from 30.5u sec
to 512 sec with resolution 30.5u sec. When timer times out, a
system reset, NMI or IRQ may happen to be decided by BIOS
programming.
Appendix A Programming the Watchdog Timer A-2
PC/104 CPU Module PFM-535S
Here are steps to setup watchdog timer:
1. Set Bit 6 = 0 to disable the timer.
2. Write the desired counter value to 3Bh, 3Ah, 39h.
3. Set Bit 6 = 1 to enable the timer, the counter will begin to count
up.
4. When counter reaches the setting value, the time out will
generate signal setting by index 38h bit[7:4]
5. BIOS can read index 3Ch Bit 7 to decide whether the Watchdog
timeout event will happen or not.
To clear the watchdog timer counter:
1. Set Bit 6 = 0 to disable timer. This will also clear counter at the
same time.
WDT1
WDT1 does not use index and data port to access WDT registers. It
uses I/O port 68H~6DH. The time resolution of WDT1 is 30.5 u
second. Here are registers information:
Appendix A Programming the Watchdog Timer A-3
PC/104 CPU Module PFM-535S
Here are steps to setup WDT1:
1. Write time into register 6Ah-6Ch.
2. Select signal from register 69h.
3. Set register 68h bit 8 to enable WDT1.
To clear the watchdog timer counter:
1. Write any value to register 67H
