Based on the Debian Sid software repository as of December 15, 2015, and powered by Linux kernel 4.3.1, Clonezilla Live 2.4.5-6 drops support for the i586 (32-bit) hardware architecture, which means that you can now use the Live CD only on i686 (32-bit non-PAE), i686-PAE (32-bit) and amd64 (64-bit) machines.
