Does Atom work?

I installed version 1.0 on my Ten Thousand Year Blog I noticed the index.php file that came with 1.0 did not include the wp-rss.php (RSS 0.92) and wp-rdf.php (RSS 1.0) links as part of the Meta section, so I added them. I also saw the Atom file and tried adding it the same way, but when I try to click the link with Internet Explorer, it tries to download the file.
Can someone explain how to use Atom with version 1.0?
Thanks,
