I recall reading somewhere that the driver installation is done in the order of the name of the driver directories, ex 001 comes before 002, I will try to get it working one more time and if that doesn't work, I'll attach the lastsession information, as I am not sure it is the right sm bus driver, because dell doesn't have an inspiron 1521 smbus driver on it's website for xp. Edit: I finally found one for an opteron system that installs for the inspiron, so all my drivers are up and running. Still, being able to change driver installation order would be nice if one driver needs another one to be previously installed.
