Winnt doesn't see SB 16 card in legacy mode

[Pccoordinator]

I have a Compaq PC with an on board sound card.&nbsp;&nbsp;I have a software package designed for voice recognition that requires a sound blaster setup using the windows NT &quot;Creative Labs Sound Blaster 1.X Pro, 16&quot; driver (not Plug and Play)<br>I disabled the onboard sound card in the BIOS and removed it from multimedia.&nbsp;&nbsp;After a reboot I setup the SB16 WinNt driver.&nbsp;&nbsp;When I click ok the &quot;sound blaster base I/O address box comes up with I/O address selected. I press the continue button the test the port address but I get the error message &quot; The sound card cannot be fopund with this port number. check your settings and try agian.&quot;<br>I try it with each available port address and get the same message.&nbsp;&nbsp;I went into Windows Nt Diagnostics to see if the I/O address was being use by anything but it was not.&nbsp;&nbsp;It will not allow me to change any other resources until I select the correct I/O address.&nbsp;&nbsp;I would appreciate any help I can get.
