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 TM 95
This item allows you to reset the configuration data or not.
This item allows you to determine the IRQ/DMA assigned to the ISA
bus and is not available to any PCI slot.
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 manufacturer.
Choices are Level and Edge.
This allows you to configure your system to the type of IDE disk
controller in use. 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 the INT# for each. Again, you
will note that the primary has a lower interrupt than the secondary.
Selecting PCI Auto allows the system to automatically determine how
your IDE disk system is configured.
Refer to the above description of PCI IDE IRQ.
