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.
IRQ Resources
This submenu will allow you to assign each system interrupt a type, depending
on the type of device using the interrupt. When you press the “Press Enter” tag,
you will be directed to a submenu that will allow you to configure the system
interrupts. This is only configurable when “Resources Controlled By” is set to
“Manual”.
