text: sound installation? my mother board is asus p4sd-la. ihave to install the sound drive. i don't have the mother board cd. then where can i get the software for sound installation. just go to the manufacturers website and download it...piece of cake!  motherboard specs:  http://h20000.www2.hp.com/bizsupport/techsupport/document.jsp?objectid=c00022505  drivers:  http://h10025.www1.hp.com/ewfrf/wc/softwaredownloadindex?lc=en&cc=us&lang=en&os=228&product=452872&dlc=en&softwareitem=pv-25770-1  please note that they use this board in many of their computers (hp) you should enter the name of your computer to download the entire driver kit...the board just uses the ac97 sound so that part easy..you should have the others on hand.
