Xth Available IRQ:
You can select four IRQs out of the 10 listed (IRQ3, 4, 5, 7, 9, 10, 11, 12, 14, 15) to
be assigned for use by the PCI device in the PCI slot.
1st Available IRQ:
This means that the first PCI device found on the PCI bus will use this IRQ. That
is, this IRQ will be assigned to the PCI interrupt number (INT#) of the first PCI
device found on the PCI bus.
2nd Available IRQ:
This IRQ will be assigned to the PCI interrupt (INT#) of the second PCI device
found on the PCI bus.
The third and the fourth available IRQ will be assigned in sequence to PCI INT#
of the third and the fourth PCI devices found on the PCI bus.
PCI IDE Card 2nd Channel:
This option can be enabled or disabled. BIOS default is Enable.
Since this channel uses IRQ15, if you want to use this channel, you have to enable
this option to make the BIOS assign IRQ15 to this channel.
PCI IDE Card IRQ Map to:
Since the main board has two IDE controllers on board, you rarely want to use an
add-on PCI IDE card. However, if you do, there are three options are available for
the PCI IDE card IRQ settings: PCI Auto, PCI-slotX and ISA.
PCI-Auto: The onboard BIOS auto-detects which PCI slot has an IDE card
inserted in.
PCI-slotX: Some old PCI IDE cards cannot be detected by the BIOS. If the
onboard BIOS cannot detect a PCE IDE card, you have to specify on which
PCI slot the IDE card is inserted, to make the BIOS assign IRQ14 for use by
the interrupt number (INT#) of this PCI slot.
ISA: If you select ISA, it means that your PCI IDE card features a
“
paddleboard
”
and a cable that can be connected to IRQ on the ISA slot,
because the BIOS will not assign any IRQ to this PCI slot.
Attention: Primary Channel and Secondary Channel : The BIOS needs two
independent interrupt number (INT#) lines to be allocated to the PCI
IDE card. Be careful not to choose the same INT# twice.
