As long as you have the correct compiler for it, you should be able to compile any kernel for any platform, irregardless of the kernel currently running. The compiler should be doing the work, converting source to machine code. If the folks at kernel.org couldn't compile a 2.6.26 kernel without a 2.6.26 kernel running, then they'd have to write kernels in Assembler, or worse, a hex editor. Michael
