Custom 404 error pages

[Sirrel Squirrel]

How do I do custom 404 error pages, with my old host it was easy as you could do it through the control panel but on my new one you can't, is there some sort of file I need to change on the server?

I'm with register1.net and I've got that .htaccess file so will give both suggestions a try, cheers
