I agree of course after reading the prep docs. A few hexdump later.... All seems fine in the headers I have examined. Entry point offset points to smthing I believe the start of code (no desassembly yet..) Load image length Flags ( showing big endian for the code) Similar for file vmlinuz...., file zImage from Leigh, x41 boot partition of my 43P-140 (whith addition of "root=..." done whith preptools), memory after loading using OF . I am wondering if I could be able to write a little piece of code for testing if it could be load-and-go'ed but I have no experience of that. May I use some makefile or equivalent ? Felipe
