Sometimes previous or unfinished installations leave 
problems that affect card operation. If the card installation 
is unsuccessful for any reason, your best course may be to 
remove the card and its software and repeat the installation 
procedures with a fresh installation of the operating 
system. Possible problems may be indicated if:

■

The card is not working.

■

Windows NT is not detecting the card.

■

The system issues a warning tone at startup.

If you are having any of these problems:

3 Select FE574B-3Com 10/100 LAN PCCard-Fast Ethernet 

and click Remove.

This procedure removes the card only. Users who choose to 
remove all networking components should remember to 
use the setup procedure described in “Setup With No 
Networking Installed” on page 15.

Card not functioning.

Open Windows NT Diagnostics. From Start menu, select
