Chapter 2 BIOS Setup 2.7 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. Figure 7. PnP/PCI Configurations 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 Choices: Disabled (default), Enabled. 2-24

2.7 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.

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 Choices: Disabled
(default), Enabled.
