Pci Irq Setting; Onboard Lan - Acer Altos 9100 Series User Manual

3.4.1

PCI IRQ Setting

This parameter allows for Auto or Manual configuration of PCI devices. If you
use plug-and-play (PnP) devices, set this parameter to Auto. The system then
automatically assigns IRQ to the PnP devices. If your PCI device is not a PnP, you
can manually assign the interrupt for each device. Refer to your manual for
technical information about the PCI card.
PCI Slots
These parameters allow you to specify the appropriate interrupt for each of the PCI
devices. You can assign IRQ3, IRQ4, IRQ5, IRQ7, IRQ9, IRQ10, IRQ11, IRQ12,
IRQ14, or IRQ15 to the slots.
The items PCI Slot 4 and Onboard SCSI share the same IRQ. Setting an interrupt
for the former automatically sets that same interrupt for the latter.
3.4.2

Onboard LAN

This item allows you to manually assign the interrupt for the onboard LAN when
the PCI IRQ Setting parameter is set to Manual . This parameter is grayed and not
user-configurable when the PCI IRQ Setting is set to Auto and when the Onboard
LAN parameter is set to Disabled .
When the PCI IRQ Setting is set to Auto , all the
IRQ setting fields become gray and non-
configurable.
Make sure that the interrupt you assign in any of
the PCI slots are not used by other devices to
avoid conflicts.
