MS-DOS 7.1 adds FAT32 support [11] for larger than 2GB and up to 2TB per volume, [12] and MS-DOS 7.0 and earlier versions of MS-DOS only support FAT12 and FAT16. [13] Logical block addressing (LBA) is supported in MS-DOS 7 for accessing larger hard disks, unlike earlier versions which only supported cylinder-head-sector (CHS)-based addressing.
Originally MS-DOS was designed to be an operating system that could run on any computer with a 8086-family microprocessor.It competed with other operating systems written for such computers, such as CP/M-86 and UCSD Pascal.

Thus, the lower the LBA value is, the closer the physical sector is to the hard drive's first (that is, outermost [5]) cylinder. CHS tuples can be mapped to LBA address with the following formula: [6] [7] LBA = (C × HPC + H) × SPT + (S − 1) where C, H and S are the cylinder number, the head number, and the sector number; LBA is the logical ...
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
