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 setting will be shown on the screen only if “Manual”
is chosen for the Resources Controlled By function.
The Choices: Disabled (default), Enabled.
Resources Controlled By
By Choosing “Auto” (default) the system BIOS will detect the
system resources and automatically assign the relative IRQ
channel for each peripheral.
By Choosing “Manual”, the user will need to assign IRQ 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”.
IRQ-3 assigned to: PCI device
IRQ-4 assigned to: PCI device
IRQ-5 assigned to: PCI device
IRQ-7 assigned to: PCI device
