Assigning IRQs for Expansion Cards
Some expansion cards may require an IRQ to operate. Generally an IRQ must be exclusively
assigned to only one device. In an standard design there are 16 IRQs available but most of
them are occupied by the system and leaves 6 free for expansion cards.
With most recent device, the BIOS automatically assign an IRQ number to PCI expansion cards.
Please make sure there are no any of two devices use same IRQs, otherwise your computer
may experience some problems when those two devices are in use at the same time.
Assigning DMA Channels for Expansion Cards
Some devices may also need to use a DMA (Direct Memory Access) channel. DMA
assignments for this mainboard are handled the same way as the IRQ assignment process
described above. You can select a DMA channel in the PCI and PnP configuration section of the
BIOS Setup utility.
