AMI BIOS Setup
The ROCKY-3703EVR uses the AMI PCI/ISA BIOS for system
configuration. The AMI BIOS setup program is designed to
provide maximum flexibility in configuring the system by offering
various options, which may be selected for end-user
requirements. This chapter is written to assist you in the proper
usage of these features.
4.1 Getting Started
When powering on the system, the BIOS will enter the Power-
On-Self-Test (POST) routines. These routines will be executed
for system test, initialization and system configuration verification.
After the POST routines are completed, the following message
appears:
" Hit DEL if you want to run SETUP"
To access AMI PCI/ISA BIOS Setup program, press <Del> key.
The following screen will be displayed at this time.

23
When choose Auto Configuration with Fail Safe Settings will
load the minimized settings for Troubleshooting. The
performance should be very poor when use this setting.
When choose Auto Configuration with Optimal Settings will
load optimized defaults for regular use. Choosing this setting will
modify all applicable settings.
4.2 Standard CMOS Setup
The Standard CMOS Setup is used for basic hardware system
configuration. The main function is for Date/Time setting and
Floppy/Hard Disk Drive setting. Please refer to he following
screen for this setup.
24
For IDE hard disk drive setup, please check the following
possible setup procedure,
1. Use the Auto setting for detection during boot up.
2. Use the IDE HDD AUTO DETECTION in the main menu to
automatically enter the drive specifications.
3.Manually enter the specifications by yourself from
the ”User“ option.
4.3 Advanced CMOS Setup
The Advanced CMOS Setup is designed for the user's tuning
best performance of the ROCKY-3703EVR board. As for
normal operation, users don‘t have to change any default
setting. The default setting is pre-set for most reliable operation.
Users can set “System Keyboard” to“ Absent” for the application
which don’t need keyboard and display.

25
You can change the value of each option by using <PgUp> and
<PgDn> key. The available values are shown on the right
screen.
Quick Boot >Enabled: this will enable the BIOS to boot quickly
when you turn on your computer. The BIOS will only check the
first 1MB of the system memory.

4.5 Power Management Setup
Power Management Setup helps user handle the ROCKY-
3703EVR board‘s “green” function. The features could shut
down the video display and hard disk to save energy for
example. The power management setup screen is as following:

29
ACPI Standby State: S1/POS, S3/STR
This item allows you to select power Management ACPI mode.
Power Management/APM: Disable, Max Saving, Min Saving,
or User Defined > Max Saving puts the system into power
saving mode after a brief inactivity period. Min Saving is almost
the same as Max Saving except that the inactivity period is
longer. User Defined allows you to set power saving options
according to your requirement.
Note: Advanced Power Management (APM) has to be
installed to keep the system time updated when the computer
enters suspend mode activated by the Power Management.
Under DOS environment, you need to add
DEVICE=C:\DOS\POWER.EXE in your CONFIG.SYS
Under Windows 3.x and Windows 95, you have to install
Windows with APM feature. A battery and power cord icon
labeled “Power” will appear in the “Control Panel”
Power Management/APM > to enable or disable the Advanced
Power Management feature.
30
Video Power Down Mode > to specify the power state of the

4.6 Peripheral Setup
These setup mainly works for Multi-I/O Chip (W83977TF).
These 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 B. if you are using the IrDA port; you have to set this
port accordingly.

31
Onboard FDC > to enable the FDC on your board. If you set it
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 A (/B). 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 B.
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 bi-directional transfer),
EPP (supports devices that comply with the Enhanced Parallel
Port specification),
32
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.
4.7 PCI / PLUG AND PLAY SETUP
The setup helps users handle the ROCKY-3703EVR board‘s
“PCI” function. All PCI bus slots on the system use INTA#, thus
all installed PCI slots must be set to this value.
Plug and Play Aware O/S > Yes or No
When PnP OS is installed, the OS may reassign interrupts when
the setting is “Yes”. When a non-PNP OS is installed or to
prevent reassigning of interrupt settings, select setting to “No”.

33
Plug and Play Aware O/S > Yes or No
When PnP OS is installed, the OS will reassign interrupts when
the setting is “Yes”. When a non-PNP OS is installed or to
prevent reassigning of interrupt settings, select setting to “No”.
Clear NVRAM > if yes, BIOS will auto-clear NVRAM on every
boot.
On Board PCI SCSI Controller > to enable and disable the on
board PCI SCSI Controller
PCI Latency Timer (PCI Clocks) > to define the latency timing
(PCI clock) for all PCI devices on the PCI bus.
PCI VGA Palette Snoop > this option is useful only for system
with more than one VGA devices connected to it through
different bus (one PCI and one ISA). To enable those various
VGA devices to handle signal from the CPU on each set of
palette registers of every video devices, it must be set Enabled.
Allocate IRQ to PCI VGA > to allocate IRQ to PCI VGA, answer
Yes and vice versa.
Offboard PCI IDE Card > to specify if an off board PCI IDE card
is installed in your computer or not. You must specify the slot
number on the board, which will be used for the card.
Offboard PCI IDE Primary (/Secondary) IRQ > to specify the
PCI interrupt that is assigned to the Primary (/Secondary) IDE
channel on the offboard PCI IDE controller.
PCI Slot (1,2,3,4) IRQ Priority > to specify the IRQ priority to be
used by the PCI devices on slot 1 to 4.
DMA Channel (0,1,3,5,6,7) > to indicate whether or not the DMA
channel is assigned for a PnP or ISA card.
IRQ (3,4,5,7,9,10,11,14,15) > to assign the displayed IRQ to be
used by a legacy ISA adapter card. The settings are ISA/EISA or
PCI/PnP.
34
4.8 Hardware Monitor Setup
This setup helps users monitor the ROCKY-3703EVR boards
on board system voltage and fan speed. The function is
implemented by on board VIA686 chip. The voltage monitoring
will cover +5V, +12V,-12V,and –5V. And there are three fan
connectors for chassis and CPU fans.
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 CN1/CN22 is correct.

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 WatchDog Timer.
443 (hex) Write Set WatchDog Time period
443 (hex) Read Enable the refresh the WatchDog Timer.
043/843 (hex) Read Disable the WatchDog Timer.
Prior to enable the WatchDog 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 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 set by the software,
please refer to the example program. Finally, we have to disable the
WatchDog 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 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.
