Reset Configuration Data
The system BIOS supports the PnP feature so the system needs to record which
resource is assigned and protect resources from conflicts. Every peripheral
device has a node which is called ESCD. This node records which resources are
assigned to it. The system needs to record and update ESCD to the memory
locations. These locations (4K) are reserved at the system BIOS.
If Disabled (default) is chosen, the system‘s ESCD will update only when the new
configuration varies from the last one.
If Enabled is chosen, the system is forced to update ESCDs and then is
automatically set to the “Disabled” mode.

The above settings will be shown on the screen only if “Manual” is chosen for the
Resources Controlled By function.
Legacy is the term which signifies that a resource is assigned to the ISA Bus and
provides for non PnP ISA add-on cards. PCI / ISA PnP signifies that a resource
is assigned to the PCI Bus or provides for ISA PnP add-on cards and peripherals.
The Choices: Disabled
(default), Enabled
