JUMPERS
The mainboard provides jumpers for setting some mainboard’s functions.
This section will explain how to change the settings of the 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 pins 1 and 2 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. The default position of the jumper is on pins 2 and 3.

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
Order 1
Order 2
Order 3
Order 4
INT B#
INT C#
