It's a relatively new target in the arch/powerpc/boot/Makefile which wraps your compressed kernel and bootcode together with a device tree blob. A device tree blob is created using a device tree source (dts). > (2)What is dts ? I don't know what is this :( A device tree source is plain text. Look inside arch/powerpc/boot/dts. A device tree is essential if you want to boot an ARCH=powerpc Linux-Kernel. Read this: http://ols.fedoraproject.org/OLS/Reprints-2008/likely2-reprint.pdf I supposed you were using 2.6.26 or 2.6.27-rcX Regards Jens
