Dell only provide support for windows XP and Vista for Dell Inspiron 6400. Basically there are compatible windows 7 drivers for this model but we need to collect it manually from different download page and different product. So here i just make a QuickList so it is easy to get all the drivers in one place. Some drivers like audio, we just need to use original vista drivers and install it in compatibility mode. So if you have problems with the installation do let me know.
