The `systems base address, i.e. where the RAM begins', I suppose it's the one from the tablet, not the pc. If so, the command $ extract-ikconfig zImage | grep PHYS_OFFSET should be given from within the tablet. Then that script should be copied on the SDcard and be run from there after mounting it. I tried, but it says `not found'. As suggested in the tutorial, I also looked for "System RAM" in /proc/iomem on the tablet. There are two occurrences: 80000000-bbffffff : System RAM and bd800000-becfffff : System RAM . Or maybe the system base address is the one of the computer? Run that script in the PC, it produces: Usage: extract-ikconfig <kernel-image> . So I'm stuck now. Please help. Thanks, Rodolfo
