The BIOS will scan for PCI IDE
devices and determine the location of
the PCI IDE device.

The BIOS will scan IRQ14 for primary
IDE INT# and IRQ15 for secondary IDE
INT# at the specified slot.
ISA
The BIOS will not assign any IRQs
even if PCI IDE card is found.
Because some IDE cards connect the
IRQ14&15 directly from ISA slot
through a card.
