BIOS Setup 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. IRQ-3 assigned to: PCI Device IRQ-4 assigned to: PCI Device IRQ-5 assigned to: PCI Device IRQ-7 assigned to: PCI Device IRQ-9 assigned to: PCI Device IRQ-10 assigned to: PCI Device IRQ-11 assigned to: PCI Device IRQ-12 assigned to: PCI Device IRQ-14 assigned to: PCI Device IRQ-15 assigned to: PCI Device 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" (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. - 29 -
