manually. When resources are controlled manually, the IRQ Resources DMA Resources and
Memory Resources can then be changed.
Computer Knowledge: ESCD (Extended System Configuration Data)
The ESCD contains the IRQ, DMA, I/O port, memory information of the system. This
is a specification and a feature specific to the Plug & Play BIOS.
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 the
PCI or ISA bus architecture.
The Award Plug and Play BIOS has the capability to automatically configure all of the boot
and PnP compatible devices. If you select Auto (ESCD), The IRQ, DMA and Memory
Resources items will be disabled, as the BIOS automatically assigns them. But if you have
trouble in assigning the interrupt resources automatically, you can select Manual to set
which IRQ and DMA are assigned to PCI/ISA PnP or legacy ISA cards.

IRQ Resources
When resources are controlled manually, assign each system interrupt a type, depending on
the type of device using the interrupt.
