I think the offset you are passing is incorrect. According to the tools at http://hg.fedoraproject.org/hg/olpc/tools/image--devel, the first partition tbegins at $DISK_BYTES_PER_SECTOR which is defined to be DISK_BYTES_PER_SECTOR=$[ $DISK_SECTOR_SIZE * $DISK_SECTORS_PER_TRACK ] Where DISK_SECTOR_SIZE=512 DISK_SECTORS_PER_TRACK=32 Which gives you an offset of 16384, not 32256. Even then, this would give you the offset of the first patition (/boot), the main partiiton (/) is located further into the disk image. I don';t have the time to figure out the maths for the offset of / just at the moment, but you can see the geometry information at http://hg.fedoraproject.org/hg/olpc/tools/image--devel?f=be0754b1c131;file=conf/partition-ext3.conf Regards, Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=| -- olpc-software mailing list [email protected] https://www.redhat.com/mailman/listinfo/olpc-software
