3.8 pnp/pci configurations
This section describes configuring the PCI bus system and PnP (Plug &
Play) feature. PCI, or
P
eripheral
C
omponent
I
nterconnect, is a system which
allows I/O devices to operate at speeds nearing the speed the CPU itself uses
when communicating with its 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.
Clear ESCD
Normally, you leave this field [Disabled]. Select [Enabled] to reset Extended
System Configuration Data (ESCD) when you exit Setup if you have installed a
new add-on and the system reconfiguration has caused such a serious conflict
that the operating system cannot boot.
Primary Graphic Adaptor
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
[Onboard/AGP]
The system initializes the installed AGP card first.
If the AGP card is not available, it will initialize the
PCI VGA card.
[PCI Slot]
The system initialize the installed PCI VGA card first.
If the PCI VGA card is not available, it will initial-
ize the AGP card.
