When adding or removing expansion cards, make sure that you unplug the power sup- ply first. Meanwhile, read the documentation for the expansion card to configure any necessary hardware or software settings for the expansion card, such as jumpers, switches or BIOS configuration.
PCI Interrupt Request Routing
IRQ, or interrupt request line, are hardware lines over which devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically connected to the PCI bus pins as follows:
| Order1 | Order2 | Order3 | Order4 |
PCI Slot1 | INT A# | INT B# | INT C# | INT D# |
PCI Slot2 | INT B# | INT C# | INT D# | INT A# |
