PnP/PCI Configurations
Clear ESCD
Normally, you leave this field Clear ESCD 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 can not boot. The settings are: Enabled and Disabled.
Resource Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all
of the boot and Plug and Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug and Play operating
system such as Windows ® 98/2000/XP. If set to “Auto”, BIOS will automatically
assign the IRQ to each device. If set to “manual”, you have to choose specific
resources by going into each of the sub menu that follows this field (a sub
menu is preceded by a “!”). The settings are: Auto (ESCD), Manual.
This section describes configuring the PCI bus system. PCI, or Peripheral
Component Interconnect, is a system which allows I/O devices to operate at
speeds nearing the speed 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.
