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 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
mainboard supports 4X (for KM266Pro)/8X (for KM400 & KM400A) 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, 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#
Order2 Order3
INT B# INT C#
INT C# INT D#
INT D# INT A#
