Introduction of BIOS 3-29
Resources Controlled By:
Two options are available: Auto or Manual. The Award Plug and Play
BIOS has the capability to automatically configure all of the boot and Plug
and Play compatible devices. But if you met trouble for assign the
interrupt resource automatically, you can select Manual to set which IRQ
and DMA are assigned to PCI/ISA PNP or legacy ISA cards.
Assign IRQ For VGA :
You can assign an IRQ for the PCI VGA or Auto.
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.
➤
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 twice the same interrupt
number (INT#).
