Yeh! D-Fend is the right choice. I've used it and it doesn't cause much overheating. of system. Just one thing bad ,or may be good, about it is that you have to mount drive letters each time you want to use it, else its fine. I remember, some of the dos games, like alladin which had problem with sound previously on my system with windows 98, now run smoothly with sound on both 98 and XP since it uses the 32 bit soundcard interface provided by Windows and not the emulated sound devices.
