The setup help user handles the ROCKY-3701 board‘s PCI
function. All PCI bus slots on the system use INTA#, thus all
installed PCI slots must be set.

Plug and Play Aware O/S > Yes or No

When PNP OS is installed, interrupts will be reassigned by the
OS when the setting is Yes. When a non-PNP OS is installed or
to prevent reassigning of interrupt settings, select setting to No.

used by a legacy ISA adapter card. The settings are ISA/EISA or
PCI/PnP.

4.7 Peripheral Setup

This setup is working mostly on Multi-I/O Chip (W83977F/877TF).
The options are used to change the Chipset‘s registers. Please
carefully change any default setting to meet your application
need perfectly. 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 Serial Port A (/B) > to specify the I/O port address of
the serial port 1(/2). If you set it Auto, the BIOS will decide the
correct I/O port address, automatically.

Serial Port B Mode > to specify the mode of serial port 2.
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.

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 are 7.
Parallel Port DMA Channel > available only if the parallel port
mode is ECP. The optimal and fail-safe settings are 3.
Onboard IDE > to define which on-board IDE controller
channel(s) to be used. Available options are: Primary, Secondary,
Both and Disabled.

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 CN3/CN16/CN17 is correct.

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.

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 low-level 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.

4.12 Auto Configuration with Fail Save Settings

This option lets you load the Fail Safe default settings when
something happens to your computer so that it cannot 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. Just 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. Just simply press <Enter> key and you
will exit the BIOS SETUP without saving the changes.

Appendix A. Watch-Dog Timer

The Watchdog Timer is a device to ensure that standalone systems can
always recover from abnormal conditions that cause the system to crash.
These conditions may result from an external EMI or a software bug.
When the system stops working, hardware on the board will perform
hardware reset (cold boot) to bring the system back to a known state.

Three I/O ports control the operation of Watch-Dog Timer.

443 (hex) Write Set Watchdog Time period
443 (hex) Read Enable the refresh the Watchdog Timer.
043/843 (hex) Read Disable the Watch-Dog Timer.

Prior to enable the Watch-Dog Timer, user has to set the time-out period.
The resolution of the timer is 1 second and the range of the timer is from
1 sec to 255 sec. You need to send the time-out value to the I/O port –
443H, and then enable it by reading data from the same I/O port – 443H.
This will activate the timer that will eventually time out and reset the CPU
board. To ensure that this reset condition won’t occur, the Watch-Dog
Timer must be periodically refreshed by reading the same I/O port 443H.
This must be done within the time-out period, please refer to the example
program. Finally, we have to disable the Watch-Dog timer by reading the
I/O port -- 843H or 043H. Otherwise the system could reset
unconditionally.

A tolerance of at least 5% must be maintained to avoid unknown routines
in the operating system (DOS), such as disk I/O that can be very time­consuming. Therefore if the time-out period has been set to 10 seconds,
the I/O port 443H must be read within 7 seconds.
