Reset Configuration Data
The system BIOS supports the PnP feature which requires the system to
record which resources are assigned and protects resources from
conflict.
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 are
reserved in the system BIOS. If the Disabled (default) option is chosen,
the system's ESCD will update only when the new configuration varies
from the last one. If the Enabled option 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 non-PnP ISA add-on cards. PCI / ISA PnP signify that
a resource is assigned to the PCI Bus or provides for ISA PnP add-on
cards and peripherals.
The Choices: Disabled (Default) / Enabled
Resources Controlled By
By Choosing "Auto(ESCD)" (default), the system BIOS will detect the
system resources and automatically assign the relative IRQ and DMA
channel for each peripheral. By Choosing "Manual", the user will need to
assign IRQ & DMA for add-on cards. Be sure that there are no IRQ/DMA
and I/O port conflicts.
The Choices: Auto (ESCD) (Default) / Manual
