^^^^^^^^^^^^^^^^^^^^^^^^^^
Equally weird. The only "standard" ones are 64 heads, 32 sectors and
255 heads, 63 sectors.
Indeed, repartitioning the USB stick with 32 sectors and 255 heads fixed
boot for a previously unbootable computer.
Thanks, Peter. I think we should document this tip in the Sugar on a
Stick wiki page and perhaps change the Fedora livecd-iso-to-disk script
to create the MBR with parted rather than fdisk.
