The Plug and Play EliteBIOS can automatically configure all the boot and Plug
and Play-compatible devices. If you select Auto, all the interrupt request (IRQ)

assigns them.

of the following types, depending on the type of device using the interrupt:

specification, requiring a specific interrupt (such as IRQ4 for serial
port 1).
PCI/ISA PnP: Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
DMA Resources (DMA-n Assigned to)

one of the following types, depending on the type of device using the

whether designed for PCI or ISA bus architecture.
