operating system such as Windows
Reset Configuration Data
This item allows you to reset the configuration data.
IRQ3/4/5/7/9/10/11/12/14/15, DMA0/1/3/5/6/7 Assigned to
These items allow you to determine the IRQ/DMA assigned to the
ISA bus and is not available to any PCI slot.
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 by your
system manufacturer. The choices are Level/Edge.
PCI IDE 2nd Channel
This item allows you to designate an IDE controller board inserted
into one of the physical PCI slots as your secondary IDE controller.
If Enabled, the External IDE controller is designated as the second-
ary controller, if Disabled, no IDE controller is occupying a PCI
slot.
PCI IDE IRQ Map To
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.
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.
