4.7 Peripheral Setup
This setup is working mostly on Multi-I/O Chip (W83977F). The
options are used to change the Chipset‘s registers. Please be
careful while making any changes to default setting as to meet
your application need properly. The only special concern is
Onboard Serial Port 2. If you want to use the IrDA port, you
have to configure the SIR or ASKIR model in the BIOS’s
Peripheral Setup’s COM2; the RS-232 COM2 will be disabled.
Onboard FDC > to enable the FDC on your board. If you
set it to Auto, the BIOS will decide if the FDC should be
enabled, automatically.
Onboard Serial Port A (/B) > to specify the I/O port
address of the serial port 1(/2). If you set it to Auto, the
BIOS will decide the correct I/O port address,
automatically.
Serial Port B Mode > to specify the mode of serial port 2.
33
IR Duplex Mode > to specify the mode of IR device that
is connected to the IR port.
IrDA Protocol > to specify the function mode if an IrDA
mode is selected.
Onboard Parallel Port > to specify the I/O port address
of the parallel port.
Parallel Port Mode > to specify the mode of parallel port.
The options are:
Normal (normal parallel port mode),
Bi-Dir (supports bidirectional transfer),
EPP (supports devices that comply with the
Enhanced Parallel Port specification),
ECP (supports devices that comply with the
Extended Capabilities Port).
Parallel Port IRQ > to assign certain IRQ to the parallel
port. The optimal and fail-safe settings is 7.
Parallel Port DMA Channel > available only if the
parallel port mode is ECP. The optimal and fail-safe
settings is 3.
Onboard IDE > to define which on-board IDE controller
channel(s) to be used. Available options are: Primary,
Secondary, Both and Disabled.
34
4.8 Hardware Monitor Setup
There is a LM78 chip on your board which can monitor on board
system voltage and fan speed. The voltage monitoring will
cover +5V,+12V,-12V,and –5V.
Note: Normal CPU Fan RPM is over than 5000 RPM. If your
CPU Fan RPM is less than that figure, something is
wrong and the CPU will be in overheat condition. Make
sure that the connection at CN12/CN13 is correct.
35
4.9 Change Supervisor / User Password
This option sets 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
always ask you to key-in password every time you enter the
BIOS SETUP. If you enter the BIOS SETUP with Supervisor
Password, you can access every setup option on the main menu
but with User Password you can only choose three setup
options (USER PASSWORD, SAVE SETTING AND EXIT and EXIT
WITHOUT SAVING). To disable these passwords, enter the
BIOS SETUP menu with Supervisor Password and then just
press the <Enter> key instead of entering a new password
when the 'Enter Password' prompt pop-up.
36
4.10 Auto-Detect Hard Disk
This option detects the parameters of an IDE hard disk drive
(HDD sector, cylinder, 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 the next IDE drives.
Note: If your IDE HDD was formatted in previous older system,
incorrect parameters may be detected. In this case, you
need to enter the correct parameters manually or lowlevel format the disk.
4.11 Auto Configuration with Optimal
Settings
This option lets you load the Optimal default settings. These
settings are best-case values which will provide the best
performance. Whenever your CMOS RAM is damaged, this
Optimal settings will be loaded automatically.
37
4.12 Auto Configuration with Fail Save
Settings
This option allows you to load the Fail Safe default settings
when something happens to your computer results in the
situation that it can no longer boot normally. These settings are
not the most optimal settings but are the most stable settings.
4.13 Save Settings and Exit
Select this option when you finish setting all the parameters
and want to save them into the CMOS. Simply press <Enter>
key and all the configuration changes will be saved.
4.14 Exit Without Saving
Select this option if you want to exit the Setup without saving
the changes that you made. Simply press <Enter> key and you
will exit the BIOS SETUP without saving the changes.

Chapter 5. E2 Key™ Function
The ROCKY-3702EV provides an outstanding E2KEY™ function
for system integrator. Based on the E
2
KEY™, you are free to
store the ID Code, Password or crucial data in the 1Kbit
EEPROM. Because the EEPROM is nonvolatile memory, you
don’t have to worry about losing these very important data.
Basically, the E
2
KEY™ is based on a 1Kbit EEPROM which is
configured to 64 words(from 0 to 63). You could access (read
or write) each word anytime.
When you start to use the E
2
KEY™ you should have the utility
in the package. The software utility will include four files as
follows,
README.DOC
E2KEY.OBJ
EKEYDEMO.C
EKEYDEMO.EXE.
The E2KEY.OBJ provides two library functions for user to
integrate their application with E
2
KEY™ function. These library
(read_e2key and write_e2key) are written and compiled in
C language. Please check the following statement, then you will
know how to use it. It is pretty easy.
unsigned int read_e2key(unsigned int address)
/* This function will return the E
2
KEY™’s data at 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
2
KEY™ at certain
address. The address range is from 0 to 63. The data value is
from 0 to 0xffff. */
39
To start to use the function in a quick way, please refer to the
included EKEYDEMO.C code before you start to operate.
Please note that the E
2
KEY™ function is based on the working
of parallel port so you should enable ROCKY-3702EV’s parallel
port, otherwise it will not work at all.

Appendix A. Watch-Dog Timer
The WatchDog Timer is provided to ensure that standalone
systems can always recover from catastrophic conditions that
cause the CPU to crash. This condition may have occurred by
external 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 time-out and either reset the CPU or
cause a NMI, depending on the setting of JP7. To ensure that
this reset condition does not occur, the WatchDog Timer must
be periodically refreshed by reading the same I/O port 443H.
This must be done within the time-out period that is selected by
jumper group JP8.
A tolerance of at least 30% 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 time out 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.
