Dude I have the same system Dell Inspiron 6000 Centtino PM chip 512MB RAM so on, but out of all the comps I own this one installs Vista everytime, and every build since 5231 I have used them all successfully!!! The drivers on the Dell Support Site that are for XP all work for Vista. Extract them all like you normallly do, but you notice that they dont install, just extract to C:/dell/drivers. If you get that far than your on the right track. Now to install the drivers goto the DEVICE MANAGER and install them each manually that way. Just click on each device and choose UPDATE DRIVERS and browse to the folder that contain all extracted drivers. IT WORKS, I dunno what your talking about all default vista drivers work, except of NETWORKING
