PCI IRQ Activated by
This items sets the method by which the PCI bus recognize that an IRQ
service is being requested by a device. Under all circumstances, you should
not change the default configuration unless advised otherwise by your
system's manufacturer. Choices are
Level

Edge

PCI IDE IRQ Map to
This items 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
device rather than a PCI controller.
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
disk drivers, you can select the 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.
