Forcing the LMS to select HTML 5 regardless of browser or platform

I have a client who wishes to avoid the use of Flash and wants to deploy courses using an LMS.  

In looking over the index_lms.html, I am wondering if I manually replace "story.html" bolded below in the html code, with "story_html5.html" will this force the course LMS to direct the use to HTML 5 content?

Code taken from index_lms.html:

<script language="JavaScript1.2">

strContentLocation = "story.html"; //Put the link to the start of the content here.
//strContentLocation = "TestAllFunctions.htm";

function LoadContent(){
window.scormdriver_content.document.location.href = strContentLocation;
}
</script>
