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 (4K) 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 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.
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.
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”.
