Chapter 3.
BIOS Setup
The ROM chip of your EM-6331 board is configured with a customized Basic
Input/Output System (BIOS) from Insyde 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:
Date and time
Motherboard Device Configuration
Memory and Cache Optimization
System Clock/ PLL Configuration
Power Management
Miscellaneous Configuration
Boot Order
The CMOS memory is maintained by battery installed on the EM-6331 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 “L. Load Defaults” from the main menu. This loads the setup default
values from the BIOS Features Setup and Chipset Features Setup screens.
2. In the main menu, choose “X. Save values and Exit ” 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 custom your system. For example, you should run
the Setup program after you:
Received an error code at startup
Install another disk drive
Use your system after not having used it for a long time
Find the original setup missing
Replace the battery
Change to a different type of CPU
Run the Insyde Flash program( Gflashit.exe) to update the system BIOS
22
Run the CMOS Setup program after you turn on the system.
instructions explain how to use the program.
On-screen
Enter the CMOS Setup program’s main menu as follows:
Turn on or reboot the system. After the BIOS performs a series of diagnostic
checks, the following message appears:
“Press F1 for SETUP”
1. Press the <F1> key to enter CMOS Setup program. The main menu
appears:
3. Choose a setup option with the arrow keys and press <Enter>.
following sections for a brief description of each setup option.
See the
In the main menu, choose “X. Save value and Exit” to save your changes and
reboot the system. Choosing “Q. Exit Without Save” ignores your changes and
exits the program. Pressing <ESC> anywhere in the program returns you to the
main menu.

Appendix A:Programming the Watchdog Timer
The EM-6331 provides a watchdog timer that resets the CPU or generates an
interrupt 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.

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:

Appendix B: System Resource
Interrupt Controller
The EM-6331 is a fully PC compatible control board, it consists of 16 ISA interrupt
request lines and most of them already in used by other part of the board. Both of
ISA and PCI expansion cards may need to use IRQs, please make sure that the IRQs
do not conflict if you would like to use extra add-on cards.
System IRQs are available to cards installed in the ISA expansion Bus first. Any
remaining IRQs then may be assigned to this PCI Bus. You are able to use the AMI
Diagnostic utility to see their map.

Appendix C: Installing CompactFlash Memory
CompactFlash™ is a very small removable mass storage device; it provides complete
PCMCIA-ATA functionality and compatibility pluse TrueIDE functionality compatible
with ATA/ATAPI-4.
CompactFlash storage products are solid state, meaning they contain no moving parts,
and provide users with much greater protection of their data than conventional
magnetic disk device.
