How can I customize my 404 - Page not found page?

Submitted by: Muhammad
Create a new page with some extra information, so that your visitors don't ever plunge on to the default boring 404 - page not found error page.
Once this page is created:
► Remember its node ID,
► Go to Administer > Site configuration > Error reporting
► Set Default 404 (not found) page to the node ID you just created
► Save your settings
You can also use the Search 404 module as an alternative.
