/** @brief The first three bytes EB 3C 90 disassemble to JMP SHORT 3C NOP. (The 3C value may be different.) The reason for this is to jump over the disk format information (the BPB and EBPB). Since the first sector of the disk is loaded into ram at location 0x0000:0x7c00 and executed, without this jump, the processor would attempt to execute data that isn't code. Even for non-bootable volumes, code matching this pattern (or using the E9 jump opcode) is required to be present by both Windows and OS X. To fulfil this requirement, an infinite loop can be placed here with the bytes EB FE 90. */
