Troubleshooting
Firstly, confirm your card type and OS. Ensure that you have installed the correct
drivers for the correct device and OS.
Verify the boot sequence. After the powering up the PC, the PCI BIOS will scan
the cards on the PCI bus. The PCI BIOS will assign the memory map, I/O map,
and IRQ number to each card. Our PCIPORT cards will have vendor ID "10B5"
or "144A". The device ID will be "9050". If you can not see such card, it
means that the PCI BIOS can not find the card. Try changing slots or cleaning
the connectors.
