Precautions
Some components on SBC-370 are very sensitive to static electric charges and can be damaged by a sudden rush of power.
To protect it from unintended damage, be sure to follow these precautions:
Ground yourself to remove any static charge before touching the SBC-370. You can do this by using a grounded wrist strap
at all times or by frequently touching any conducting materials that are connected to the ground.
Handle your SBC-370 by its edges. Don't touch IC chips, leads, or circuitry if not necessary.
Do not plug any connector or jumper while the power is on.
Do not put your SBC-370 unprotected on a flat surface because it has components on both sides.
BATTERY REPLACEMENT CAUTION
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's instructions.

is equipped with a high performance Intel® Celeron processor (up to 500 MHz) or
Pentium III (FC-PGA) 500 MHz (or above) processor, and advanced high performance
multi-mode I/O.
This board has a built-in DiskOnChip™ (DOC) Flash Disk for embedded applications.
The DOC Flash Disk is 100% compatible to hard disk. Users can use any DOS com
mand without any extra software utility. The DOC currently is available from 2 MB to
144 MB.
An advanced high performance super AT I/O chip - Winbond W83977TF is used in

WATCHDOG TIMER
The Watchdog Timer is provided to ensure that standalone systems can recover from
catastrophic conditions that cause the CPU to crash. This condition can occur from ex
ternal EMI or a software bug. When the CPU stops working correctly, hardware on the
board will either perform a hardware reset (cold boot) or a Non-Maskable Interrupt
(NMI) to bring the system back to a known state.
Two I/O ports control the Watchdog Timer:
443 (hex) Read Enable to refresh the Watchdog Timer
043 (hex) Read Disable the Watchdog Timer
To enable the Watchdog Timer, a read from I/O port 443H must be performed. This
will enable and activate the countdown timer which will eventually timeout and
either reset the CPU or cause a NMI, depending on the setting of JP5. To ensure
that this reset condition does not occur, the Watchdog Timer must periodically be
refreshed by reading the same I/O port 433H. This must be done within the time
out period that is selected by JP12.
-
-
A tolerance of at least 20% must be maintained to avoid unknown routines
within the operating system (DOS), such as disk I/O that can be very time consuming. Therefore, if the timeout period has been set to 10 seconds, the I/O port
443H must be read within 7 seconds.
Note: When exiting a program, it is necessary to disable the Watchdog Timer, otherwise
the system will reset.
E2KEY™ FUNCTION
The SBC-370 provides an E2KEY™ function for system integrators. Based on the E2KEY
utility, you can freely store the ID Code, Password, or Critical Data in the 1Kbit
EEPROM. Because the EEPROM is nonvolatile memory, you don't have to worry about
losing important data.
The E2KEY utility is based on a 1Kbit EEPROM which is configured to 64 words
(from 0 to 63). You can access (read or write) each word at any time.
2
The E
will include four files as files:
•
KEY utility is provided on a CD-ROM with your system. The software utility
README.DOC
•
E2KEY.OBJ
•
EKEYDEMO.C
•
EKEYDEMO.EXE
9 Features
The E2KEY.OBJ provides two library functions for you to integrate your application
2
with the E
KEY function. The read_e2key and write_e2key libraries are written and
compiled in C language. To implement them, refer to the functions below:
*/unsigned int read_e2key(unsigned int address): This function will return the
2
E
KEY data to a certain address. The address range is from 0 to 63. Return data is
one word, 16 bits.
*/void write_e2key(unsigned int address, unsigned data): This function will write
the given data to E
value is from 0 to 0xffff.
To begin using this function, refer to the included EKEYDEMO.C code.
2
Key to a certain address. The address is from 0 to 63. The data
Note: The E
2
KEY function is based on the parallel port. Therefore, you should enable
SBC-370's parallel port or it will not work.
CONNECTING TO AN ATX POWER SUPPLY
To Connect ATX Power Supply to the Backplanes and/or the ISBC Card
1. Disconnect the AC cord from the power supply to prevent sudden electric surge.
2. Connect the ATX power supply switch to the pin 17 (power button) and pin 19
(+5VSB) of CN7 (multi panel) on the board.
Figure 1. SBC-370
(through Power
Button and +5VSB).
•
To turn off the power supply, push the ATX power switch button for about four seconds.
•
To turn the system on, push the button once.

3 AMI BIOS Setup Menus
The SBC-370 uses the AMI PCI/ISA BIOS for system configuration. The AMI BIOS
setup program is designed to provide maximum flexibility in configuring the sys
tem by offering various options for end user requirements. This section is pro
vided to assist you in the proper usage of these features.
GETTING STARTED
When you turn the system on, the BIOS will enter the Power-On-Self-Test routines.
These routines will be executed for system test and initialization and system con

STANDARD CMOS SETUP
The standard CMOS Setup is used for basic hardware system configuration. The main
26
function is for Date/Time setting and Floppy/Hard Disk setting. Refer to the following
screen.
Date/Time:
Use the left arrow, right arrow, and Enter keys to move from one field to the
next. The numeric keys, 0-9, are used to change the field values. To set the date
(MM:DD:YYYY), select one of the fields (Month, Day, or Year) and then press either
PgUp or PgDn to set it to the current Month, Day, and Year. Follow the same procedure
for setting the Time (HH/MM/SS). The hour is calculated according to a 24-hour mili
tary clock, i.e., 00:00:00 through 23:59:59.
Note: It is not necessary to enter the seconds or type zeros in front of numbers.
IDE hard disk drive setup: Use one of the following setup procedures:
•
Use the Auto setting for detection during boot-up.
•
Use the Auto-Detect Hard Disk option in the main menu; the computer will
automatically detect the HDD specifications.
•
Manually enter the specifications from the User option.
ADVANCED CMOS SETUP
The Advanced CMOS Setup is designed for optimizing the performance of the
SBC-370. Under normal operation, you do not have to change any default set
tings. The default settings are preset for the most reliable operation.

HARDWARE MONITOR SETUP
There is a LM78 chip that can monitor onboard system voltage and fan speed.
The voltage monitoring will cover +5V, +12V, -12V, and -5V.
Note: Normal CPU fan RPM is more than 5000 RPM. If your CPU fan RPM is less than
5000 RPM, something is wrong and the CPU will be in overheat condition. Make sure
that the connection at CN12/CN13 is correct.

CHANGE SUPERVISOR/USER PASSWORD
Set a password that is used to protect your system and Setup Utility. Supervisor
Password has higher priority than User Password. Once you setup the password,
the system will ask you to enter the password every time you enter the BIOS SETUP.
If you enter the BIOS SETUP with the Supervisor Password, you can access every
setup option on the main menu. With a User Password, you can only choose three
setup options (Change User Password, Save Setting and Exit, and Exit Without Saving). To disable
these passwords, enter the BIOS SETUP menu with the Supervisor Password and
then press the Enter key instead of entering a new password when the Enter Password
prompt appears.
AUTO-DETECT HARD DISK
This option detects the parameters of an IDE hard disk drive (HDD sector, cylin
der, head, etc.) automatically and will put the parameters into the Standard
CMOS Setup screen. Up to 4 IDE drives can be detected and the parameters will
be listed in the box. Press Y if you accept these parameters. Press N to skip to the
next IDE drive.
Note: If your IDE HDD was formatted in a previous system, incorrect parameters may
be detected. In this case, you need to enter the correct parameters manually or low-level
format the disk.

AUTO CONFIGURATION WITH OPTIMAL SETTINGS
This option lets you load the Optimal default settings. These settings are
best-case values that will provide the best performance. Whenever your CMOS
RAM is damaged, the Optimal settings will be loaded automatically.
AMI BIOS Setup Menus 38
AUTO CONFIGURATION WITH FAIL SAFE SETTINGS
This option allows you to load the Fail Safe default settings when your computer
cannot boot normally. These settings are not optimal, but are the most stable.
SAVE SETTINGS AND EXIT
Select this option when you finish setting all the parameters and want to save
them into the CMOS. Simply press the Enter key and all the configuration changes
will be saved.
EXIT WITHOUT SAVING
Select this option if you want to exit the Setup without saving the changes that you
made. Simply press the Enter key and you will exit the BIOS SETUP without saving the
changes.
