MS-7051G M-ATX Mainboard
The mainboard provides one AGP slot and three 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 neces-
sary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.

CNR Slot

The CNR slot allows you to insert the CNR expansion cards. CNR is a specially
designed audio, or modem riser card for ATX family motherboards. Its main process-
ing is done through software and controlled by the motherboard's chipset.

PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hard-
ware 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:
PCI Slot 1
PCI Slot 2
PCI Slot 3
AGP Slot
2-24
