Now, you can download Fedora core live CD :D
After lots of feedback, bug fixing and testing of the beta live CD announced 3 weeks ago, I'm pleased to announce the first official Fedora live CD. This live CD is based on packages from the Fedora Core 6 (codenamed "Zod") and Fedora Extras package collections and is such 100% free software.
The live CD is currently only available for i386 architectures. Support for other architectures including ppc and x86_64 is planned. The live cd weighs around 682MB. Download from official web site
