Normally, the operating system can identify the device and then find and load the drivers. The port identifies itself and the port slot sends the message to the BIOS, which will then check any configuration data for the PCI serial port.
This scans for any hardware connected to the PCI bus and then asks for the detected PCI serial port’s identification. The computer’s system BIOS initiates the plug-and-play BIOS. Step 2 – Wait for the Computer to Identify the PCI Serial Port Plug the serial port into the PCI slot by matching the serial port’s edge with the port. It looks like a bar with holes for the PCI serial port’s pins. Find an empty PCI slot, also called a PCI bus. This is the biggest board in the CPU and typically wears a green background. Remove the CPU cover by unscrewing the screws or pulling the panel back. Unplug the central processing unit (CPU) from the electrical outlet. Step 1 – Plug the PCI Serial Port into a PCI Slot
