Chapter3 Award BIOS Setup 3 - 27
²
Resources Controlled By
The Award Plug and Play BIOS has the capacity to
automatically configure all the boot and Plug and Play devices.
If you choose Auto, you cannot select IRQ DMA and memory
base address fields, since BIOS automatically assigns them.
The choices: Auto (ESCD), Manual.
²
IRQ Resources
When resources are controlled manually, assign each system
interrupt a type, depending on the type of device using the
interrupt. There are two types for choice: Legacy ISA and
PCI/ISA PnP.
Legacy ISA:
Devices compliant with the original PC AT bus
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.
² DMA Resources
When resources are controlled manually, assign each DMA
channel a type, depending on the type of device using the DMA
channel. There are two types for choice:
Legacy ISA and
PCI/ISA PnP.
Legacy ISA:
Devices compliant with the original PC AT bus
specification, requiring a specific DMA channel
PCI/ISA PnP:
Devices compliant with the Plug and Play
standard, whether designed for PCI or ISA bus architecture.
