Master boot record (MBR) valid flag:
• 0 means no MBR was detected
• 1 means a valid MBR was found
Partition boot record (PBR) valid flag:
• 0 means no PBR was detected
• 1 means a valid PBR was found
Master boot record (MBR) FAT12 flag:
• 0 means FAT12 flag is not set in MBR
• 1 means FAT12 flag is set in MBR
Partition boot record (PBR) FAT12 flag:
• 0 means FAT12 flag is not set in PBR
• 1 means FAT12 flag is set in PBR
Master boot record (MBR) FAT16 flag:
• 0 means FAT16 flag is not set in MBR
• 1 means FAT16 flag is set in MBR
Partition boot record (PBR) FAT16 flag:
