Getting author pages to display more than default number of posts

Hello,

I followed the codex instructions for creating author pages (author.php) on my multi-author blog, which also list posts contributed by each author:
https://codex.www.ads-software.com/Author_Templates

However, the author pages will only display the number of posts that my Reading Settings specify as the number of posts for blog pages to show. For instance, I have authored 8 posts, my Reading Settings are set to display 5 posts, so my author page only displays the last 5 posts I have contributed — not my total number of posts.

Using the $curauth method specified in the codex example above, how can I show more posts on my author pages?

I’ve included my code below:

<?php get_header(); ?>
   <div id="content" class="narrowcolumn">
      <!-- This sets the $curauth variable -->
<?php
if(isset($_GET['author_name'])) :
$curauth = get_userdatabylogin($author_name);
else :
$curauth = get_userdata(intval($author));
endif;
?>

<h2>Latest Posts by <?php echo $curauth->nickname; ?></h2>
<!-- Find out how to do showposts= to display all posts by an author -->

<div style="float:right;">
<?php userphoto($wp_query->get_queried_object()) ?>
</div>
<p><?php echo $curauth->user_description; ?></p>

<ul>
<!-- The Loop -->
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
  <li>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>">
<?php the_title(); ?></a> on
<?php the_time('F jS, Y'); ?>
  </li>

  <?php endwhile; else: ?>
     <p><?php _e('No posts by this author.'); ?></p>

	<?php endif; ?>
<!-- End Loop -->
</ul>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

Thank you!
