Yes they do - take a look at the "Command Line Execution" topic in the help file (press F1) - it's all detailed in there. But for expediency these are the options:
/mode: "createnew" or "upgrade" - this is the execution mode of the installer. /server: The name of the target server. /database: The name of the target database. /username: A user on the target database that has full administration privileges /password: The user's password. /silent A flag indicating that no UI should be displayed during the install.
