Is there a "special" URL param to force SWFObject to show alt content?

Question

I remember doing this years ago, but can't remember if it was with SWFObject. Anyone herd of this before? I guess it would basicly disable SWFObject from switching the altContent for the SWF.

I though it was something like: www.mysite.com?noflash=true

But can't remember the real one (if it exists).

Thanks
