Clear CMOS Jumper: JBAT1

There is a CMOS RAM on board that has a power supply from external battery to keep the data of
system configuration. With the CMOS RAM, the system can automatically boot OS
every time it is turned on. If you want to clear the system configuration, use the
JBAT1 (Clear CMOS Jumper) to clear data.
MSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin position. Avoid
clearing the CMOS while the system is on; it will damage the mainboard.
The mainboard provides one AGP slot and five 32-bit PCI bus slots.

AGP (Accelerated Graphics Port) Slot

The AGP slot allows you to insert the AGP
graphics card. AGP is an interface specification
designed for the throughput demands of 3D graphics. It introduces a 66MHz, 32-bit channel for the
graphics controller to directly access main memory. The slot supports 8x/4x AGP card.

PCI (Peripheral Component Interconnect) Slots

The PCI slots allow you to insert the expansion cards to meet your needs. 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, acronym of interrupt request line and pronounced I-R-Q, are hardware lines over which
devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically connected to
the PCI bus INT A# ~ INT D# pins as follows:
Order 1
PCI Slot 1 INT A#
PCI Slot 2 INT B#
PCI Slot 3 INT C#
PCI Slot 4 INT D#
PCI Slot 5 INT B#
Order 2 Order 3
