Figure 3-8A. PnP/PCI Configurations Setup Menu

Force Update ESCD:

Two options are available: Disabled or Enabled. The default setting is Disabled. Normally, you should 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 a serious conflict that prevents the operating system from booting.

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.

Resources Controlled By:

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 devices compliant with the original PC AT bus specification require a specific interrupt. PCI PnP devices comply with the Plug and Play standard, whether designed for the PCI or legacy bus architecture.

Two options are available: Auto (ESCD) or Manual. The default setting is Auto (ESCD). The Award Plug and Play BIOS has the capability to automatically configure all boot and Plug and Play compatible devices. If you select Auto (ESCD), all of the interrupt request (IRQ) fields become unselectable, as the BIOS automatically assigns them.
