1.5 Precautions
Please make sure you properly ground yourself before handling the CB-7960
control board or other system components. Electrostatic discharge can be
easily damage the CB-7960 control board.
Do not remove the anti-static packing until you are ready to install the CB-7960
control board.
Ground yourself before removing any system component from it protective
anti-static packaging. To ground yourself, grasp the expansion slot covers or
other unpainted parts of the computer chassis.
Handle the CB-7960 control board by its edges and avoid touching the
components on it.
CompactFlashTM card is a small removable mass storage device. It can
provide complete PCMCIA-ATA functionality and compatibility plus True IDE
functionality compatible with ATA/ATAPI-4.
CompactFlashTM storage products are solid state form factor, it means they
contain no moving parts. Thus, it provides users with much greater protection
of the data than conventional magnetic disk device.
The ROM chip of your CB-7960 board is configured with a customized Basic
Input/Output System (BIOS) from Phoenix-Award BIOS. The BIOS is a set of
permanently recorded program routines that give the system its fundamental
operational characteristics. It also tests the computer and determines how
the computer reacts to instructions that are part of programs.
The BIOS is made up of code and programs that provide the device-level
control for the major I/O devices in the system. It contains a set of routines
(called POST, for Power-On Self Test) that check out the system when you turn
it on. The BIOS also includes CMOS Setup program, so no disk-based setup
program is required CMOS RAM stores information for:
z Date and time
z Memory capacity of the main board
z Type of display adapter installed
z Number and type of disk drives
The CMOS memory is maintained by battery installed on the CB-7960 board.
By using the battery, all memory in CMOS can be retained when the system
power switch is turned off. The system BIOS also supports easy way to
reload the CMOS data when you replace the battery of the battery power lose.
3.1 Quick Setup
In most cases, you can quickly configure the system by choosing the following
main menu options:
1. Choose “Load Optimized Defaults” from the main menu. This loads the
setup default values from the BIOS Features Setup and Chipset Features
Setup screens.
2. Choose “Standard COS Features” from the main menu. This option lets
you configure the date and time, hard disk type, floppy disk drive type,
primary display and more.
3. In the main menu, press F10 (“Save & Exit Setup”) to save your changes
and reboot the system.

3.2 Entering the CMOS Setup Program
Use the CMOS Setup program to modify the system parameters to reflect the
options installed in your system and to customize your system. For example,
you should run the Setup program after you:
z Received an error code at startup
z Install another disk drive
z Use your system after not having used it for a long time
z Find the original setup missing
z Replace the battery
z Change to a different type of CPU
z Run the Phoenix-Award Flash program to update the system BIOS
Run the CMOS Setup program after you turn on the system. On-screen
instructions explain how to use the program.
Enter the CMOS Setup program’s main menu as follows:
1. Turn on or reboot the system. After the BIOS performs a series of
diagnostic checks, the following message appears:
“Press DEL to enter SETUP”
2. Press the <DEL> key to enter CMOS Setup program. The main
menu appears:

precharge time”, ”Precharge delay”, “System
Memory Frequency” by manual.
CAS Latency Time
llow to determine the timing delay (in clock
cycle) that elapses before DRAM carries out a
read command after receiving it.
DRAM RAS# to CAS# Delay Allows you to insert a delay between the RAS
(Row Address Strobe) and CAS (Column
Address Strobe) signals. The delay occurs when
the DRAM is written to, read from or refreshed.
DRAM RAS# Precharge Allow you to set the number of cycles required for
the RAS to accumulate its charge before the
DRAM refreshes.
Precharge Delay The field specifies the idle cycles before
precharging an idle bank.
System Memory Frequency Select “Auto” to be set by hardware. The other
options are 533MHz and 667MHz.
SLP_S4# Assertion Width When removing and reapplying power to the

if processing comes to a stop. This function ensures greater system reliability in
industrial stand-alone and unmanned environments.
In order to enable the watchdog timer, you have to output the value of the watchdog
timer interval to the controller. The value range is from 01H to FFH, and the related
time watchdog timer interval is 1 sec to 255 sec.

FF 255 sec
If you want to disable the watchdog timer, just set the timer interval value to 00H.
After setting the timer interval value, the watchdog timer begins to count down. You
have to refresh the watchdog timer, so that the watchdog timer will return to its initial
value; otherwise, your system will reset after a time-out. The following program
shows how to set the watchdog timer:

Note: This XX value range is from 01H to FFH, and the related
watchdog timer interval is 1 sec. to 255 sec. (as in the previous
description).
Using the Demo Program
Update the System BIOS as follows:
1. Run Program 1
2. Run Program 2 (load the timer interval of 1EH, 30 seconds)
3. Run your Application Program #1 (Be sure your Application Program will
finish within 30 seconds)
4. Run Program 1
5. Run Program 2 (change the timer interval value to 3CH, 60 seconds)
6. Run your Application Program#2 (Be sure your Application Program will be
finished within 60 seconds)
7. Run Program 1
8. Run Program 2 (reload the timer interval value of 3CH, 60 seconds)
9. Run Program 1
Run Program 3 (Load the timer interval of 00H, and disable the watchdog timer function)
