More Info
A) What happens if your system cannot detect the controller card?
It might be IRQ conflicts, which are caused by other onboard PCI cards. In this case, you have to use different PCI slot to reinstall the card. Also, make sure all the contacts and gold fingers of the card are clean.
B) Do you need to assign an IRQ for the controller card?
No, the card is PNP ready. It is automatically assigned an IRQ by the Windows OS (98SE/ME/2000/XP). You do not need to assign it.
C) What printer mode do you use?
It is recommended to use it as SPP mode. You can change it in your system BIOS.
D) How do you know whether the driver is installed correctly?
Please check your device manager to see whether there is any yellow exclamation mark. If there is one, then the driver is not installed correctly. You need to reinstall the driver again.
E) How do you get the update driver or support help?
You can download the latest driver from Chipset manufacturer web site: http://www.moschip.com/html/download_drivers.html
