Trying to use install_switches in the sqlserver module. What format should the parameter be in?

I'm not certain what "hash of switches means". I've tried variations of the following: install_switches => ['INSTALLSQLDATADIR="S:\"','TCPENABLED="1"','/SQLUSERDBDIR="D:\"','/SQLUSERDBLOGDIR="L:\"','/SQLTEMPDBDIR="T:\"'], }
