Installation
Jumpers
The mainboard provides jumpers for setting the mainboard’s functions. This
section will explain how to change settings for your mainboard’s functions
through the use of the jumpers.
Clear CMOS: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an
onboard battery power supply. The long-life battery has a lifetime of at least
5 years. If you want to clear the system configuration data from the CMOS
RAM, use the CLEAR_CMOS (Clear CMOS jumper). You can clear the
CMOS by shorting 1-2 pin while the system is off. Then return it to the 2-3
pin position. Shorting the jumper while the system is on will damage the
mainboard.

Peripheral Component Interconnect: PCI
The PCI slot allows you to insert PCI expansion card. When adding or
removing expansion cards, make sure that you unplug the power supply first.
Meanwhile, read the documentation for the expansion card to make any
necessary hardware or software settings for the expansion card, such as
jumpers, switches or BIOS configuration.
PCI Interrupt Request Routing
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are
hardware lines over which devices can send interrupt signals to the
microprocessor. The “PCI & LAN” IRQ pins are typically connected to the
PCI bus INT A# ~ INT D# pins as follows:
PCI Slot

Set Supervisor / User Password
When you select this function, a message as below will appear on the screen:
Type the password, up to eight characters in length, and press Enter. The
password typed now will clear any previously set password from CMOS
memory. You will be prompted to confirm the password. Re-type the
password and press Enter. You may also press Esc to abort the selection
and not enter a password.
To clear a set password, just press Enter when you are prompted to enter
the password. A message will show up confirming the password will be
disabled. Once the password is disabled, the system will boot and you can
enter Setup without entering any password.
When a password has been set, you will be prompted to enter it every time
you try to enter Setup. This prevents an unauthorized person from changing
any part of your system configuration.
There are two types of passwords you can set. A Supervisor password and a
User password. When a Supervisor password is used, the user can start
BIOS Setup program and change the settings of the setup menus. When a
User password is used, the user can start the BIOS Setup program but does
not have the right to change the settings of the setup menus.

BIOS Setup
Additionally, when a password is enabled, you can also have BIOS to
request a password each time the system is booted. This would prevent
unauthorized use of your computer. The setting to determine when the
password prompt is required is the Security Option of the Advanced BIOS
Features menu. If the Security Option is set to System, the password is
required both at boot and at entry to Setup. If set to Setup, password prompt
only occurs when trying to enter Setup.
