Jeff,I think you can "decorate" the manufacturer section of your INF file to specify the target OS version.
Take a look here: http://msdn2.microsoft.com/en-us/library/ms794359.aspx I hope that helps. -Dan----- Original Message -----
From: "Jeff Pages" <jeff@xxxxxxxxxxxxxxxx> Subject: [wdmaudiodev] Driver selection Date: Wed, 16 May 2007 16:56:09 +1000 For a particular device, I have a WaveRT driver for Vista and a WavePCI driver for earlier systems, each with their own inf files. What can I do to stop Vista installing the WavePCI driver, or earlier operating systems from trying to install the WaveRT driver? There's a lot of stuff in the WDK about distinguishing between 9x and NT-based drivers in INF files, but I can't find anything that gets more version-specific. Jeff
