4.7.1 Resources Controlled by
The Award Plug and Play BIOS can automatically configure all the boot and Plug and Play-
compatible devices. If you select Auto, all the interrupt request (IRQ) and DMA assignment
fields disappear, as the BIOS automatically assigns them.
4.7.2 PnP O/S Installed:
Select Yes if the system operating environment is Plug-and-Play aware (e.g., Windows 95).
4.7.3 Reset Configuration Data
Normally, you leave this field Disabled. Select Enabled to reset Extended System
Configuration Data (ESCD) when you exit Setup if you have installed a new add-on and the
system reconfiguration has caused such a serious conflict that the operating system cannot
boot.
4.7.4 IRQ # Assigned to
When resources are controlled manually, assign each system interrupt 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
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.
4.7.5 DMA # Assigned to
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:
