Resources Controlled By:
When you select Auto, the BIOS will automatically assign the IRQ and
DMA to PCI / ISA PnP . When this option is Manual, you can choose which
IRQ or DMA can assign to PCI / ISA PnP .
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:
Three options are available for this item: PCI Auto, PCI-slotX and ISA.
ä
PCI-Auto: The onboard BIOS auto-detects which PCI slot has an IDE
card inserted in.
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#).
Assign IRQ for PCI VGA :
You can assign IRQ for PCI VGA or not .
On Board FDD Controller:
This is to Enable or Disable the Onboard FDD Controller.
