Chapter 3 BIOS Setup
BIOS Overview
BIOS (Basic Input and Output System) is solidified in the flash memory on the CPU
board. Its main functions include: initialize system hardware, set the operating status
of the system components, adjust the operating parameters of the system components,
diagnose the functions of the system components and report failures, provide hardware
operating and controlling interface for the upper level software system, guide
operating system and so on. BIOS provides users with a human-computer interface in
menu style to facilitate the configuration of system parameters for users, control power
management mode and adjust the resource distribution of system device, etc.
Setting the parameters of the BIOS correctly could enable the system operating stably
and reliably; it could also improve the overall performance of the system at the same
time. Inadequate even incorrect BIOS parameter setting will decrease the system
operating capability and make the system operating unstably even unable to operate
normally.
BIOS Parameter Setup
Prompt message for BIOS setting may appear once powering on the system. At that
time (invalid at other time), press the key specified in the prompt message (usually
<Del>) to enter BIOS setting.
When the BIOS setting in CMOS is destroyed, system may also require entering BIOS
setting or selecting certain default value.
All the setup values modified by BIOS are saved in the CMOS storage in system. The
CMOS storage is powered by battery; unless clearing CMOS contents, or else its
contents will not be lost even if powered off.
Note! BIOS setting will influent the computer performance directly. Setting
parameter improperly will cause damage to the computer; it may even unable to power
on. Please use the internal default value of BIOS to restore the system.
Our company is constantly researching and updating BIOS, its setup interface may be
a bit different. The figure below is for reference only; it may be different from your
BIOS setting in use.

Watchdog Programming Guide
This board provides a programmable watchdog timer (WDT) up to 255 levels
and time by minute or second. Watchdog timeout event can be programmed
to reset system or generate maskable interrupts.
The available IRQ numbers for this board are: 3, 4, 5, 7, 9, 10 and 11.
Please modify the corresponding IRQ number in PCIPnP of BIOS Setup
interface into “Reserved” before using.
The following describes WDT program in C language. The steps to program
WDT are listed as follows:
Enter WDT programming mode;
Set WDT operating mode/enable WDT/disable WDT.

b. Time by second:
outportb(pm_base+0x65, 0x80);
(4) Enable/Disable WDT

Troubleshooting and Solutions
NO. Phenomenon Troubleshooting and Solution
Analysis: could be the problem of the CMOS battery.
1
BIOS setting
cannot be saved
Solution: measure the CMOS battery via multi-meter;
if the voltage is insufficient, replace with a new battery;
re-set the BIOS and save again.
Analysis: may be due to ill connection. Remove the
power from power socket on motherboard, you may
detect that certain pin of the motherboard power has
been collapsed to one side after several times insertion.
2
The computer
can be power-on
occasionally
Solution: power off the computer and remove the
power plug; erect the bended power pin with tweezers
and re-insert in the power socket. Reboot the computer
and test for several times until the problem no longer
exits.
Analysis: U disk is a high-speed USB2.0; when
connecting with the computer, it prompts that a
high-speed device has been connected with a low-speed
connector, which indicates that the connector on
motherboard is regarded as a USB1.1 port.
3
When
connecting with
U disk, the
system prompts
that a
high-speed
device has been
connected with a
low-speed
connector.
Solution: enable the USB high-speed transmission
mode on motherboard. Different motherboards may
have different settings. Modify the FULLSPEED
option to HISPEED in USB device option.
Analysis: it could be resulted from improper operation
when inserting or removing the memory and cause
abnormal operation of the components on motherboard.
Focus on the circuit related to the memory on
motherboard.
4
The screen has
no display after
replacing with a
new memory
and cannot enter
system; even
when the former
memory is
re-installed, the
system cannot
be booted as
well.
Solution: check the hardware such as memory, video
card first; if it shows that the hardware are all OK, then
check the circuit around the memory slot on
motherboard carefully; you may detect that the two
pins connected with the golden finger in the first
memory slot are shorted while the second memory slot
is normal, then you may know that there is short circuit
in the first memory slot. Remove the two pins to their
original location with tweezers carefully, insert the
memory, reboot the system and the system will be
Appendix
EC3-1813 SERIES - 45 -
booted smoothly.
Analysis: the data cable of the hard disk may get
knocked when installing the CD-ROM, which leads to
ill connection of the hard disk data cable, or the master
and slave jumpers on hard disk and CD-ROM are
wrongly set.
5
The system
cannot be
booted after
replacing a
CD-ROM
Solution: check the data cable of the hard disk and the
IDE connectors on hard disk and motherboard first; if
there are no problem, then check the master and slave
jumper setting. You may detect that the hard disk and
CD-ROM are connected with different data cables
while their jumpers are all set to master; thus, the hard
disk cannot be booted. Set the CD-ROM jumper to
slave and then re-install it.
Analysis: make sure whether the PCI card functions
normally; re-insert the PCI card or insert it into another
PCI slot to see whether it is normal; find out the power
type in use (AT or ATX); find out users’ requirement for
the PCI card voltage.

No PCI card can
be detected after
entering the
system
Solution: if the PCI card functions abnormally, replace
with a new one; if it functions normally when
re-inserted or inserted in another PCI slot, then there is
something wrong between the PCI card and the slot. If
AT power is adopted and the PCI card requires 3.3V
voltage, then the AT power shall be replaced with ATX
power because AT power cannot provide 3.3V voltage.
(Suggestion: when purchasing power, please check
whether the PCI card in use requires 3.3V voltage or
not).
Analysis: devices are not connected; no drivers are
loaded; devices are broken.

Cannot find
peripheral
devices
Solution: check whether the cable between the device
and the motherboard is normal; if it is normal, replace
with a new cable to make sure the connection is OK.
Re-install the device driver and check whether it can be
recognized; check whether the device is normal; if the
device is normal, then check whether the device is
compatible with the motherboard.
