that affect card operation. Possible problems include:
■
One or both of the card functions not working.
■
Windows not detecting the card.
■
The system issuing a warning tone at startup.
If you are having any of these problems, remove the LAN+Modem card and
software using the procedures below, then reinstall the card.
