3-6 PNP/PCI Configuration
This section provides IRQ and DMA setting information. By choosing the PNP/PCI
Configuration option from the CMOS Setup Utility menu (Figure 3-1), the screen below
is displayed. This sample screen contains the manufacturer's default values for the
mainboard.
A. PNP OS Installed
If you want to install a PNP compatible OS(such as Windows 95) set to Yes.
B. Resources Controlled By
When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA
information. Instead, it will refer to the items in the setup menu for assigning IRQ
& DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy
information.
ESCD (Extended System Configuration Data) provides a detailed format of
the configuration data structures stored in flash memory. Each data structure
defines the resources used by a device or a card in the system. This includes
legacy and PCI/ISA PnP devices.
C. FDD IRQ Can Be Free
This function allows user to choose if the FDD IRQ is able to be freed up. The
default setting is Yes and this does not allow the IRQ to be free.
