Agp (Accelerated Graphics Port) Slot; Pci (Peripheral Component Interconnect) Slots; Pci Interrupt Request Routing - MSI 848PM User Manual

MS-7037 M-ATX Mainboard
The motherboard 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 mainboard supports one AGP 8x slot.

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:
PCI Slot 1
PCI Slot 2
PCI Slot 3
2-22
Slots
Order 1 Order 2
INT G# INT H#
INT F# INT G#
INT E# INT F#
