Open two frames with same form

[neta]

<form action="http://www.msn.com/search" method="get" onSubmit="search(this)" name="root" target="_self">
<input name="qfront" type="text" style="width: 280px" />
<input type="submit" value="Search" style="height: 26px" name="root" />

How can I use the code above for when I click on the search buton on the master page with one frame, open the search results on _top with two frames.
Top frame with banner and the main frame with the search results of MSN?

Ex:
Master page = one frame. Click on search buton and opens one page x.htm with two frames. Top frame y.htm with banner and main frame z.htm with the search results of MSN

Put a page on your site in the form action, and have that page set a frameset that opens the 2 frames.
