Eleven options are available: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14, 15. Default setting is Auto.
This item allows the system to automatically specify the IRQ number for the device installed
on PCI slots. Which means, the system can specify the fixed IRQ number for the device
installed on the PCI slots (PCI slot 1 to PCI slot 5). This is a useful function when you want
to fix the IRQ for a specific device.
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.
