Additional Notes
Crystal/Cirrus Logic CL4299 multimedia device. When you upgrade many Acer notebooks (mine is a Travelmate 506T) from win98 to w2000 you will lose sound support. Acer support is absolutely no help, so after searching for days I found this driver from Crystal/Cirrus Logic's site (hard to find). Works great, full support now.
