hi Wolfgang ,
    yah i have stripped off ppcbootloader as u saud inthe mail ,
  i  have set cross compiler for ppc on my i386 machine ,
after compiling zImage i give command make zImage.initrd
so that r4,r5 contain initrd offset and size
i am getting initrd offset as 9099b

initrd_load routine is called ,he is checking at this loaction for
start of ramdisk image ,he is not getting it, so he says couldnt
find valid ramdisk image

what can be the problem
thanks in advance
regards
somshekar

How do you load the image? Linux uses a special segment  in  the  ELF
file  for the initrd image; maybe your bot loader does not understand
this, and drops it?
