Follow these instructions at your own risk. This worked perfectly on my Cobalt RaQ4, but may not work on all machines. I cannot be held responsible for your machine.

The process below is how I installed Debian 3.1 Sarge on my Cobalt RaQ4. I used various sources of information to do this, but the most help came from the Debian Cobalt HOWTO that I found on the Internet. At the time this article was written, the site was down, so I've reposted the original on my site. I'll simply copy most parts of the original document because it is written SO well. So if you compare the two, you'll see a lot of similarities, but I've added/removed/changed the things that didn't work for me. I'll also include lessons learned throughout this process. Mostly things I wanted the cobalt to do, but it just won't do it. Many thanks to Tim Hockin, a former Cobalt engineer who has continued hacking the Cobalt kernel long after Sun backed out. Without his initial work on the Cobalt ROM Kernels, there's no way we could have been using these machines with a modern OS. So...let's get started. Shall we?
