3.7 PCI Configuration
Both the ISA and PCI use on the CPU card use system IRQs & DMAs. You must set up
the IRQ and DMA assignments correctly through the PCI Configuration Setup
utility,otherwise the CPU Card will not work properly.
Selecting “PCI CONFIGURATION” and the Screen appears as ...

Slot X Using INT# : Some PCI devices use interrupts to signal that they need to use the
PCI bus. Other devices, notably most graphics adapters, do not need interrupt service
at all. Each PCI slot can activate up to four interrupts, INT#A, INT#B, INT#C and INT#D.
By default, a PCI slot is allowed INT#A. Assigning INT#B has no meaning unless the
device in the slot requires two interrupt services rather than just one. Likewise, using
INT#C can only mean the device requires three interrupts; and using INT#D, four
interrupts. The default, AUTO, allows the PCI controller to automatically allocate the
interrupts.
PCI IRQ Activated by : Leave the IRQ trigger set at Level unless the PCI device
assigned to the interrupt specifies Edge-triggered interrupts.
PCI IDE 2nd Channel : You can use this selection to enable or disable the second IDE
channel.
