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. Follow the instructions below to clear the 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.

AGP (Accelerated Graphics Port) Slot

The AGP slot allows you to insert the AGP
graphics card. AGP
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.

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, 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 IRQ pins are typically
connected to the PCI bus INT A# ~ INT D# pins as follows:
Order1
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#
