The driver I mentioned in a previous post is for the Volcano IC100, it's made by a company called Mito-tech. Go to the website below (just cut and paste the link) and select IC100 from the drop down menu. This driver only works with Windows 98/ME/XP and 2000 as far as I'm aware, it may work with Vista but not too sure.
