This article presents a list of commands used by MS-DOS compatible operating systems, especially as used on IBM PC compatibles. Many unrelated disk operating systems use the DOS acronym and are not part of the scope of this list. In MS-DOS, many standard system commands are provided for common tasks such as listing files on a disk or moving ...
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 ...
Specifically, the above will create a 2 GB logical partition, provided that adequate space is available, and assign it the drive letter 'F:'. [5] The installed disks and their associated volumes and/or partitions can be viewed using these commands: list disk list volume list partition The sel command will select them.
The category Internal DOS commands deals with articles about DOS commands built into the command processor (COMMAND.COM, 4DOS.COM, NDOS.COM, DOSPLUS.COM, ...
To allow the use of more FAT partitions in a compatible way, a new partition type was introduced in PC DOS 3.2 (1986), the extended partition (EBR), [14] which is a container for an additional partition called logical drive. Since PC DOS 3.3 (April 1987), there is another, optional extended partition containing the next logical drive, and
IBM introduced the first version of fdisk (officially dubbed "Fixed Disk Setup Program") in March 1983, with the release of the IBM PC/XT computer (the first PC to store data on a hard disk) and the IBM PC DOS 2.0 operating system. fdisk version 1.0 can create one FAT12 partition, delete it, change the active partition, or display partition data. fdisk writes the master boot record, which ...
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.
For example, if the second or third hard disk is of SCSI type and, on DOS, requires drivers loaded through the CONFIG.SYS file (e.g. the controller card does not offer on-board BIOS or using this BIOS is not practical), then the first SCSI primary partition will appear after all the IDE partitions on DOS. Therefore, DOS and for example OS/2 ...
