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. If it is set to ISA/EISA, the BIOS will not assign any
IRQ to PCI devices.
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
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.
28
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 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.
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 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
Vtt, Vcore, Vio, +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/CN4 is correct. Anyway, the above RPM
figure is for reference only. Different brand may give different
figure.
30
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.
31
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.
32
4.12 Auto Configuration with Fail Save Settings
This option lets you load the Fail Safe default settings when
something happens to your computer and causes 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.

E2 Key™ Function (optional)
The ROCKY-P258BX provides an optional outstanding E2KEY™
function for system integrator. Based on the E2KEY™, you can
free to store the ID Code, Password or Critical Data in the 1Kbit
EEPROM. Because the EEPROM is nonvolatile memory, you
don’t have to worry for losing very important data.
Basically the E2KEY™ is based on a 1Kbit EEPROM which is
configured to 64 words(from 0 to 63). You could access (read or
write) each word at any time.
When you start to use the E2KEY™ 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 E2KEY™ 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 implement it easily.
unsigned int read_e2key(unsigned int address)
/* This function will return the E2KEY™’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)
34
/* This function will write the given data to E2KEY™ at certain
address. The address range is from 0 to 63. The data value is
from 0 to 0xffff. */
To easily start to use the function, please refer to the included
EKEYDEMO.C code at first.
Please note that the E2KEY™ function is based on the working
of parallel port. So you should enable the ROCKY-P258BX’s
parallel port, otherwise it will not work.

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 JP12. 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 JP13.
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.
36
Appendix B. ATX Power Supply
The following notes show how to connect ATX Power Supply to the
backplanes and the ROCKY-P258BX.
Please, disconnect the AC cord of the Power Supply from the AC source
when you plug-in DC connector to prevent sudden electric surge to the
board.
Connect the ATX power supply switch to the pin 18 (power button) and
pin 20 (+5VSB) of CN2 (multi panel) on the board.
If you wish to turn off the power supply, please push the ATX power
switch button for about 4 sec. And to turn ON the system, simply push
the button once.
