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
7.1 PNP OS Installed
When set to YES, BIOS will only initialize the PnP cards used for the boot sequence (VGA,
IDE, SCSI). The rest of the cards will be initialized by the PnP operating system like
Window™ 95. When set to NO, BIOS will initialize all the PnP cards. For non-PnP
operating systems (DOS, Netware™), this option must set to NO.
The Choices: No
(default), Yes.
7.2 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.
