This is a driver for a Realtek ALC202A codec chip which covers several operating systems. Specifically, I am posting this for other owners of Trigem Gendale motherboard owners aka Pavilion 533w owners who have been duped and lied to by the specification sheet at HP, because it states that the codec on a trigem glendale is an Analog Devices ADI1981. That is a lie, the codec is actually a Realtek ALC202A. This driver will work perfectly when you are installing 98SE on an HP Pavilion 533w box.
Good luck, thanks to the site masters for this website, it helped me on this quest. Now I want to help them and others.
