To use SFS you just have to use HDToolBox to add the FileSystem to the harddisks RDB. Simply, open the partition view and chose 'Add FileSystem'. You also need to specify the FileSystem to use for your partition.
After that your HD controller should load the FileSystem and mount the drive automatically independent from which media you boot.
If you have multiple controllers I recommend to use the latest HDToolBox that is in OS3.9 BB2.
