PCI/PNP Resource Management
IRQ and DMA Settings
The BIOS has the capability to automatically configure all of the boot and Plug & Play compatible
devices. Normally, you should set them as [Available], so that the BIOS can automatically assign
the IRQs and DMA channels. In the old days, you might assign each IRQ or DMA channel to a
Legacy ISA card, and you had to change the setting to [Reserved] to reserve IRQ/DMA for this
ISA card. This happened mostly on the ISA bus sound cards. Legacy ISA devices are compliant
with the original PC AT bus specification and require a specific interrupt / DMA channel to function
properly.
Now, ISA bus is disappeared on the motherboard, only PCI PnP devices are considered. PCI PnP
devices, on the other hand, adhere to the Plug & Play standard and can use any interrupt / DMA
channel. The IRQ/DMA assignments here are just to reserve some particular resources for them,
and you can go to Device Manager for the assignments.
