PCI Interrupt Mapping INTx# - Assignment of the PCI interrupts
defines which PCI interrupt is switched to which ISA interrupt. For the change to
take effect, you must switch your device off and then on again after the
Setup BIOS
has terminated.
A multifunctional PCI board can use all PCI interrupts, if need be.
If you use a setting other than
Auto
, the Plug&Play functionality of the system BIOS
for PCI boards is deactivated.
The PCI interrupts INTA#, INTB# and INTC# are assigned as follows:
PCI slot 1 = INTA#, PCI slot 2 = INTB#,
PCI slot 3 = INTC#, PCI slot 4 = INTD#
Auto
The PCI interrupts are assigned automatically in accordance with
the Plug&Play guidelines (default entry).
Disabled
No PCI interrupt is used for the PCI board in the assigned PCI
slot.
IRQ03, IRQ04, IRQ05, IRQ06, IRQ07, IRQ09, IRQ10, IRQ11, IRQ12, IRQ14, IRQ15
The PCI interrupt is switched to the selected ISA interrupt. You
may not select an ISA interrupt that is used by a component on the
system board (e.g. controller) or an ISA board.
VGA Interrupt - Assigning PCI-VGA interrupt
assigns PCI interrupt to the screen controller on the built-in PCI board. If you have
not defined any other interrupt with
PCI Interrupt Mapping
, IRQ9 is assigned.
Enabled
The interrupt is assigned to the screen controller on the built-in PCI
board (default entry).
Disabled
The interrupt can be used for other add-on boards.
