For example, if you want to move your hard disk to another computer and don't want to
®
re-install Windows NT, then you can specify the IRQ for the device installed on the new
computer to fit the original computer settings.
If you specify the IRQ in this item, then you cannot specify the same IRQ to the ISA
bus, otherwise, it will cause a hardware conflict.
This feature is for the operating system that will record and fix the PCI configuration status,
if you want to change it.
For the relations between the hardware layout of PIRQ (the signals from the ICH chipset),
INT# (means PCI slot IRQ signals) and devices, please refer to the table below:
