Solution 1:

I have a copy of the 3.0.3 ISO and yes, that does appear to be the last one they made available. If you want to try your luck with the download, here's the MD5 hash of the copy that I have: C8FDA701B884FE9A96CB6AD10154F2C1. I've used it before and it works OK, but be aware that it's rather limited in which network cards it supports. You might need to pull the hard drive out of your physical box so you can run the clone operation on another machine. For best results, find one that has a broadcom card.
