/**
 * MBR (Master Boot Record) partition table is a traditional way of
 * MS-DOS to partition larger hard disc drives into distinct
 * partitions.
 * 
 * This table is stored in the end of the boot sector (first sector) of
 * the drive, after the bootstrap code. Original DOS 2.0 specification
 * allowed only 4 partitions per disc, but DOS 3.2 introduced concept
 * of "extended partitions", which work as nested extra "boot records"
 * which are pointed to by original ("primary") partitions in MBR.
