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.
