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
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), PCI EX.
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.
