Sound Card Is Not Detected If Network Card Uses Same Address

The information in this article applies to:

 - Microsoft Windows 95

If you upgrade from Windows version 3.1 or Windows For Workgroups version
3.11 to Windows 95 and have the Media Vision Windows 3.1 sound card drivers
installed, Setup may display a message during hardware detection that it is
receiving no response from one of the hardware components it is looking
for. In Windows 95, neither the Setup program nor the Add New Hardware
program detects the Media Vision MV-1100 Blue Light Special sound card when
a DEC DE201 Etherworks Turbo/TP network card is also installed on the
computer.

Both the network card and the sound card are configured to use the same
address. When Windows 95 hardware detection writes to a particular address
that is being used by a sound card, the network card's response hides the
sound card's response, causing a conflict.

Reconfigure the network card to use a different address, and then have
Windows detect the hardware again using the Add New Hardware program.

The DEC DE201 Etherworks Turbo/TP network card uses Input/Output address
ranges 200h-20Fh. The Media Vision MV-1100 Blue Light Special sound
card also use this range. The same problem may occur with computers that
have both a network card and a sound card that use overlapping addresses.
