The version included with PC DOS 3.0 and 3.1 is hard-coded to transfer the operating system from A: to B:, while from PC DOS 3.2 onward you can specify the source and destination, and can be used to install DOS to the harddisk. The version included with MS-DOS 4 and PC DOS 4 is no longer a simple command-line utility, but a full-fledged installer.
The Main code page (Russian: Основная кодировка) is an 8-bit code page used in DOS. It was devised in 1986 by a research group at the Academy of Science of the USSR. [ 1 ] The other code page by the same group is known as the " Alternative code page " ( Russian : Альтернативная кодировка ) which is nearly ...
Code page 737 (CCSID 737) [1] (also known as CP 737, IBM 00737, and OEM 737, [2] MS-DOS Greek [3] or 437 G [4]) is a code page used under DOS to write the Greek language. [5] It was much more popular than code page 869 although it lacks the letters ΐ and ΰ.
MS-DOS / PC DOS and some related disk operating systems use the files mentioned here. System Files: [1] IO.SYS (or IBMBIO.COM): This contains the system initialization code and builtin device drivers; MSDOS.SYS (or IBMDOS.COM): This contains the DOS kernel. Command-line interpreter (Shell): COMMAND.COM: This is the command interpreter.
With the release of PC DOS version 3.3 (and the near identical MS-DOS 3.3) IBM introduced the code page numbering system to regular PC users, as the code page numbers (and the phrase "code page") were used in new commands to allow the character encoding used by all parts of the OS to be set in a systematic way. [10]
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, [citation needed] although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used.
Code page 866 (CCSID 866) [2] (CP 866, "DOS Cyrillic Russian") [3] is a code page used under DOS and OS/2 [4] in Russia to write Cyrillic script. [5] [6] It is based on the "alternative code page" (Russian: Альтернативная кодировка) developed in 1984 in IHNA AS USSR and published in 1986 by a research group at the Academy of Science of the USSR.

Under real mode operating systems, such as DOS, calling INT 13h would jump into the computer's ROM-BIOS code for low-level disk services, which would carry out physical sector-based disk read or write operations for the program. In DOS, it serves as the low-level interface for the built-in block device drivers for hard disks and floppy disks.
