Chapter 3 Award BIOS Setup 45
3.7.1 Resources 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 95. The
default setting is Auto.
3.7.2 Reset Configuration Data
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.
3.7.3 IRQ-xx assigned to : PCI/ISA PnP
These fields indicate whether or not the displayed IRQ for each field
is being used by a legacy (non-PnP) card. Two options are available:
PCI/ISA PnP or Legacy ISA. The first option, the default setting,
indicates that the displayed IRQ is not used to determine if an ISA
card is using that IRQ. If you install a legacy ISA card that requires a
unique IRQ, you must set the field for that IRQ to “Legacy ISA”. Say
for example that you install a legacy ISA card that requires IRQ10.
You must then set “IRQ-10 assigned to :” as “Legacy ISA”.
3.7.4 PCI IRQ Activated by
This sets the method by which the PCI bus recognizes that an IRQ
service is being requested by a device. Under all circumstances, you
should retain the default configuration unless advised otherwise by
your system’s manufacturer. The default setting is Level.
