Limiting Posts w/ have_posts()

I am using Options>Reading>Reading Options>Blog Pages>Show at Most>X #of posts to display the last post and only the last post on my index.php page.

My problem is that when I browse to say all posts in that category or to the archives I still only see that one latest post and I’d like to see ALL of the posts. Does that make sense? So, can someone tell me if I can pass have_posts() a limit of # of entries to display?

Take a look at my site: https://www.sixminutes.ca to get an idea of what I mean. make sure you look at the archives and browse by category …

Thanks for the help!
