D-Bracket™2 Connector: Jdb1 (Optional); Agp (Accelerated Graphics Port) Slot; Pci Interrupt Request Routing - MSI 848P Neo-V Series Instruction Manual

MSI Reminds You...
Please do not fold the Serial ATA cable into 90-degree angle. Otherwise, the loss of data may occur
during transmission.
D-Bracket™2 Connector: JDB1 (Optional)
The mainboard comes with a JDB1 connector for you to connect to D-Bracket™2.
D-Bracket™2 is a USB Bracket that supports both USB1.1 & 2.0 spec. It integrates
four LEDs and allows users to identify system problem through 16 various
combinations of LED signals.

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 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, acronym 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 INT B#
PCI Slot 2 INT C#
PCI Slot 3 INT D#
PCI Slot 4 INT B#
PCI Slot 5 INT A#
