In computing, format is a command-line utility that carries out disk formatting. It is a component of various operating systems , including 86-DOS , MS-DOS , IBM PC DOS and OS/2 , Microsoft Windows and ReactOS .
For example, in DOS 5, if the current directory is C:\TEMP, then TRUENAME command.com will display C:\TEMP\COMMAND.COM (which does not exist), not C:\DOS\COMMAND.COM (which does and is in the PATH). This command displays the UNC pathnames of mapped network or local CD drives. This command is an undocumented DOS command.
The command-line sg_format program may be used to issue the command. [19] A variety of sector sizes may be chosen, but are not available on all devices: 512, 520, 524, 528, 4096, 4112, 4160, and 4224-byte sectors. [20] Although the SCSI command provides many options, even resizing, it does not touch on the track layer where low-level format ...
The Linux fdformat program works with the kernel floppy driver. It simply formats a floppy disk using whatever parameters is already known to the system. [1] The setfdprm can be used to provide the system with unusual formatting parameters with which to format.
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.
However, due to the lack of a controlled shutdown procedure (as found in modern operating systems), many users saw the appearance of the MS-DOS prompt as an indication that it was safe to switch off the computer, which was typically the case prior to MS-DOS 6.0. Microsoft addressed this issue in MS-DOS 6.2 where the write caching was still ...
NewDos/80 had many options for specifying specific low-level disk configurations. Settings such as diskette formats, disk drive types, track geometry and controllers could be configured using the PDRIVE command. [1] In version 2.1, Apparat added support for hard disk drives via an external bus adapter.
FASM (flat assembler) is an assembler for x86 processors. It supports Intel-style assembly language on the IA-32 and x86-64 computer architectures. It claims high speed, size optimizations, operating system (OS) portability, and macro abilities.
