S MANUAL
RESOURCES CONTROLLED BY:
The Award Plug & Play BIOS has the capacity to automatically configure
all the boot and Plug & Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug & Play operating
system such as Win 95. The available choices are Auto and Manual.
RESET CONFIGURATION DATA:
Normally, set this field to Disable. 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.
PCI IDE 2ND CHANNEL:
Select Disabled to deactivate the onboard PCI IDE second channel interface,
if you install a secondary add-in IDE interface.
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.
PCI IDE IRQ MAP TO:
This allows you to configure your system to the type of IDE disk controller
in use. By default, Setup assumes that your controller is an ISA (Industry
Standard Architecture) device rather than a PCI controller. The more
apparent difference is the type of slot being used.
If you have equipped your system with a PCI controller, changing this
allows you to specify which slot has the controller and which PCI interrupt
(A, B, C or D) is associated with the connected hard drives.
Remember that this setting refers to the hard disk drive itself, rather than
individual partitions. Since each IDE controller supports two separate hard
drives, you can select INT# for each. Again, you will note that the primary
has a lower interrupt than the secondary as described in “
Slot x Using INT# ”
above.
Selecting “ PCI Auto ” allows the system to automatically determine how
your IDE disk system is configured.
