That was my impression to for the last couple years, but we had discussion about it on the beagleboard group. The rom doesn't care, it was x-loader that was coded for sector 63.. http://www.sakoman.com/cgi-bin/gitweb.cgi?p=x-loader.git;a=commit;h=f24393836812798cac755eeaeae37112d709b09d Discussion: http://groups.google.com/group/beagleboard/browse_thread/thread/2a41df7801eca451/23f2921ef00c0f9e#23f2921ef00c0f9e > >> >> https://github.com/RobertCNelson/omap-image-builder/blob/master/tools/setup_sdcard.sh#L348 >> > > I partitioned a card with the exact same commands you use in > setup_sdcard.sh (fdisk to create the boot partition and parted for the > root one), and then used our script to populate it (without changing the > partitions), but it didn't boot.
