I want it to always boot up in OFF mode
just switch it off manually, and quit.
next time you run HFS, it will be OFF.
if this does not work, then there is some problem in saving your configuration.
ATM there are only few parameters possible by the command line, and there is no paramer for switch off.
HFS has lots of config things. maybe a good way to make all available is a single parameter that let you load an additional ini file that will overlap the existing one.
