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.
