Follow the instructions in this guide.

This is the meat and veg of it though...

The link in your master page:

<link rel="search" type="application/opensearchdescription+xml" href="http://mysite.com/browserplugin.xml" title="My Site Search" />  

The browserplugin.xml file mentioned above should look like this:

<?xml version="1.0"?>
<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">
    <ShortName>My Site Search</ShortName>
    <Description>My Site Search</Description>
    <Image height="16" width="16" type="image/x-icon">http://mysite.com/favicon.ico</Image>
    <Url type="text/html" method="get" template="http://mysite.com/search/{searchTerms}"/>
</OpenSearchDescription>

Note that you should (obviously) change that urls appropriately according to your website. Specifically the Url in the OpenSearchDescription in order to match your search url.
