Prova questo:




<BODY>

<SCRIPT LANGUAGE="JavaScript">

<!-- Begin
// If it's Internet Explorer, use automatic link
// Be sure to change the "http://www.YourWebSiteHere.com\"
// to the URL you want them to bookmark.
if (document.all){
document.write('<A HREF="javascript:history.go(0);" onClick="this.style.behavior=\'url(#default#homepa ge)\';this.setHomePage(\'http://www.YourWebSiteHere.com\');">');
document.write('<font size="5" color=6699FF face=arial>Click Here to Make My Web Page Your Homepage</font></a>');
}
</script>
</BODY>



Ovviamente devi cambiare [www.YourWebSiteHere.com] con la tua home page
