system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when
communicating with its own special components. This section covers some very technical items and it is
strongly recommended that only experienced users should make any changes to the default settings.

When resources are controlled manually, assign each system interrupt as one of the following types,
depending on the type of device using the interrupt:

IRQ4 for serial port 1).
PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus
architecture.
When resources are controlled manually, assign each system DMA channel as one of the following types,
depending on the type of device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific DMA channel
