Setup Problems in Windows 95
Setup can configure your PC Card only if Card Services is
functioning correctly and resources (I/O ports and IRQs) are
available. When these two requirements are met, Setup
can automatically determine a configuration for you.
Power Management
Microsoft’s Windows 95 version B (also referred to as OSR 2)
power management utility is not properly implemented for
supporting multifunction PC cards. Power-management
problems may occur when you restart your computer after
installing the card. Since the LAN+Modem card’s built-in
power management feature manages power for the card,
the Setup program automatically reconfigures power
management. If you did not run the Setup program, watch
for the following symptoms:
■
The computer may not see the network.
■
In the Control Panel/System/Device Manager list, a
yellow exclamation point may appear next to the 3Com
LAN+Modem card listing under Network Adapters, but
the Multifunction Adapter and Modem functions will
appear to be functioning correctly.
■
The computer may stop responding.
■
The computer may reboot in Safe Mode.
■
Rebooting gets as far as the Windows logo screen then
hangs.
If you are having any of these problems, you may have to
disable the power management utility for PC Card modems
using the following procedure:
1
Open the Control Panel application.
2
Double-click the Power icon.
3
Select the
PC-Card Modems
tab.
4
Clear the check box labeled
Turn off PC-Card modem
when not in use
by removing the check symbol.
5
Click
OK
and Reboot.
