18 CHAPTER 4: SETUP FOR WINDOWS NT
Uninstalling the Card
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:
1 Remove the LAN card from the card slot.
2 Open Network/Adapters.
3 Select FE574B-3Com 10/100 LAN PCCard-Fast Ethernet
and click Remove.
4 Reboot and reinstall the card.
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
Programs/Admin Tools/Windows NT Diagnostics.
Check for resource conflicts and make sure the settings
for the LAN card are valid.
