...= 0 and the 'data size' field stores the entry point address). Attached to the e-mail there is the 'whole-wip.diff' file with our current changes to syslinux (applied over syslinux-4.06-pre2 tag). When we test the code, we find the entry point. But syslinux fails to boot with 'syslinux_shuffle_boot_pm'. The symptomatic failure (we don't know if it's the root failure) comes from the function 'syslinux_compute_movelist' called from 'syslinux_do_shuffle'. The last 'printf' shown from inside 'syslinux_compute_movelist' is the one marked with "########...
