MS-7005 Micro ATX Mainboard
The motherboard 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 4x/2x 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. The orange PCI slot (PCI5) also works as a
communcation slot, which allows you to insert the communcation card.

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
2-20
