PCI IRQ Activated by
To tell the chipset the IRQ signals input is level or edge trigger.
PCI IDE IRQ Map to
The options in this category are : PCI-AUTO, PCI-SLOTx, ISA.
PCI-AUTO :
The system BIOS will scan for PCI IDE devices & deter-
mine the location of the PCI IDE device.
PCI-SLOTx (x=1~4) :
The BIOS will assign IRQ 14 for primary IDE
INT#, and IRQ 15 for secondary IDE INT# for the specified slot.
ISA :
The BIOS will not assign any IRQs even if PCI IDE card is found.
Because some IDE cards connect the IRQ 14 & 15 directly from ISA
slot through a extended cord. (this cord is called Legacy Header)
Primary IDE INT#
To tell which INT# does the primary IDE port on PCI IDE cad is using
for its interrupts.
Secondary IDE INT#
To tell which INT# does the secondary IDE port on PCI IDE cad is using
for its interrupts.
