Hardware Setup Slots The motherboard provides one PCI Express x1 slot, one PCI Express x16 slot, and two 32-bit/33MHz PCI slots. PCI (Peripheral Component Interconnect) Express Slots The PCI Express slots support high-bandwidth, low pin count, and serial interconnect technology. You can insert the expansion cards to meet your needs. W hen adding or removing expansion cards, make sure that you unplug the power supply first. PCI Express architecture provides a high performance I/O infrastructure for Desktop Platforms with transfer rates starting at 2.5 Giga transfers per second over a PCI Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general purpose I/O. Also, desktop platforms with PCI Express Architecture will be designed to deliver highest performance in video, graphics, multimedia and other sophisticated applications. Moreover, PCI Express architecture provides a high performance graphics infrastructure for Desktop Platforms doubling the capability of existing AGP 8x designs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics controllers, while PCI Express x1 supports transfer rate of 250 MB/s. PCI Express x16 slot PCI Express x1 slot PCI (Peripheral Component Interconnect) Slots The PCI slots allow you to insert the expansion cards to meet your needs. W hen 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 Slot 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 pins as follows: PCI Slot 1 PCI Slot 2 Order 1 INT E# INT F# Order 2 INT F# INT G# Order 3 INT G# INT H# Order 4 INT H# INT E# 2-25
