Introduction of BIOS 3-23

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.
