1. The MultiPort does not work properly even after it has been successfully installed
One of major reasons MultiPort boards do not work properly is mostly interrupt
collisions. This is not a frequent problem because PCIe boards are automatically
assigned interrupts. However, reasons for interrupt collisions or abnormal operation of
PCIe boards can be classified into three.
Since there are no reserved resources in the system, PCIe may use an already
assigned interrupt number. It is required to install MultiPorts again by disabling IRQ
numbers (such as IRQ3 and IRQ7) that have been assigned but not used in the CMOS
setup program in order to make those interrupts available.
