Introduction of BIOS 3-31
ä 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.
ä 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 twice
the same interrupt number (INT#).
Note: Since the interrupt number of the PCI slot is connected
according the design described below, there are some limitations,
be careful.
+ The INT#A signal of the first PCI slot, the INT#B signal of
the second PCI slot, the INT#C signal of the third PCI slot
and the INT#D signal of the fourth PCI slot, are the same,
so be careful not to use them simultaneously.
+ The INT#B signal of the first PCI slot, the INT#C signal of
the second PCI slot, the INT#D signal of the third PCI slot
and the INT#A signal of the fourth PCI slot, are the same,
so be careful not to use them simultaneously.
+ The INT#C signal of the first PCI slot, the INT#D signal of
the second PCI slot, the INT#A signal of the third PCI slot
and the INT#B signal of the fourth PCI slot, are the same,
so be careful not to use them simultaneously.
+ The INT#D signal of the first PCI slot, the INT#A signal of
the second PCI slot, the INT#B signal of the third PCI slot
and the INT#C signal of the fourth PCI slot, are the same,
so be careful not to use them simultaneously.
On Board USB Controller:
This is to Enable or Disable the onboard Universal Serial Bus (USB)
controller.
