4.5.7 PnP/ PCI Setup Defaults
This section describes configuring the PCI bus system. PCI (Peripheral Component
Interconnect) is a system that allows I/O devices to operate at speeds nearing CPU’s
when they communicate with own special components.
All of options described in this section are important and technical and it is strongly
recommended that only experienced users could make any changes to the default
settings.
4.5.7.1 PNP OS installed
This field allows you to use a Plug-and-Play (PnP) operating system.
Please set it as "No " if the operating system has no PnP function or to avoid reassigning
the IRQs by the operating system.
The choice: Yes, No.
4.5.7.2 Reset Configuration Data
In case a conflict occurs after you assign the IRQs or after you configure your system, you
can enable this function to allow your system to automatically reset your configuration and
reassign the IRQs, DMAs, and I/O address.
The choice: Disable, Enable.
4.5.7.3 Resources Controlled By
Default setting is “Auto (ESCD)”. This setting allows the BIOS to self detect setting and
Plug-and-Play devices during start up. The user can select and configure IRQs under
"Manual" mode.
The choice: Auto (ESCD), Manual.
