7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal Computer

Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed of

the CPU itself uses when communicating with its own special components. This section

covers some very technical items and it is strongly recommended that only experienced users

should make any changes to the default settings.

Init Display First

With systems that have multiple video cards, this option determines whether the

primary display uses a PCI Slot or an AGP Slot.

The Choices: PCI Slot (default), AGP.

Re se t Config urat io n 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.
