This driver should work for Conexant AC-Link audio devices on windows 2000. I used it for my ze5460us HP laptop / notebook and it worked like a charm. The XP drivers were available from HP's website but the windows 2000 one's WERE NOT. An HP tech recommended this file to me even though it is for another model notebook. If you have a Conexant AC-Link audio device running on win2k I'd give this a whirl.
