Some real BIOS+MBR demand that the last 2 bytes in a boot sector be 0xAA55. So sometimes the first sector has only 510 usable bytes. If the same code reads the second sector, then that sector also might have only 510 usable bytes. Those 2+2 bytes mattered to me when I wrote mine. -- -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
