PCI Interrupt Mapping INTx#
defines which PCI interrupt is switched to which ISA interrupt.
With multifunctional PCI boards, all PCI interrupts can be used. The controllers
on the system board do not need any PCI interrupts.
If you use a setting other than
Auto
, the Plug&Play functionality of the system
BIOS for PCI boards is deactivated.
With monofunctional PCI boards, the PCI interrupts are designed as follows:
PCI slot 1 = INTA#, PCI slot 2 = INTB#, PCI slot 3 = INTC#
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.
PCI Device, Slot #n: Default Latency Timer
specifies the lowest number of clock cycles in which a PCI master module can be
active at the PCI bus.
n
stands for the number of the PCI slot.
Yes
The value predefined by the PCI module is accepted. The entry in
the corresponding field for
PCI Device, Slot #n: Latency Timer
is
ignored. (Default entry)
No
The value predefined by the PCI module is ignored. The value set
in the corresponding field for
PCI Device, Slot #n: Latency Timer
determines the number of clock cycles.
PCI Device, Slot #n: Latency Timer
Condition: the corresponding field for
PCI Device, Slot #n: Default Latency Timer
must be set to
No
.
The field defines the lowest number of clock cycles in which a burst can be
transferred on the PCI bus.
n
stands for the number of the PCI slot.
0000h
to
0280h
Number of clock cycles (default entry =
0040h
).
