An example of a computer with one operating system per storage device is a dual-booting computer that stores Windows on one disk drive and Linux on another disk drive. In this case a multi-booting boot loader is not strictly necessary because the user can choose to enter BIOS configuration immediately after power-up and make the desired drive ...
Amstrad licensed both MS-DOS 3.2 and Digital Research DOS Plus, which was largely compatible with MS-DOS and included some features from CP/M and the ability to read CP/M disks. Only one of these operating systems could be used at a time. They also licensed the GEM windowing system, which supported the customized CGA hardware of the 1512. [10]
In Windows NT and OS/2, the operating system uses the aforementioned algorithm to automatically assign letters to floppy disk drives, optical disc drives, the boot disk, and other recognized volumes that are not otherwise created by an administrator within the operating system. Volumes that are created within the operating system are manually ...
Even though each 1541 has its own on-board disk controller and disk operating system, it is not possible for a user to command two 1541 drives to copy a disk (one drive reading and the other writing) as with older dual drives like the 4040 that was often found with the PET computer, and which the 1541 is backward-compatible with (it can read ...
The DOS/V operating system enabled IBM clones to display Japanese text by using a software font only, giving a chance for global PC manufacturers to enter the Japanese PC market. The PC-98 is a non-IBM compatible x86 -based computer and is thus capable of running ported (and localized) versions of MS-DOS and Microsoft Windows .
The boot loader; performs basic system initialization options such as loading the hardware abstraction layer and boot-time device drivers, prior to passing control to the Windows kernel. In versions prior to Vista, NTLDR and IA64ldr also display menus to the user if multiple operating systems are defined in boot.ini, or if F8 is pressed.
Multi-boot systems are computers where the user can boot into more than one distinct operating system (OS) stored in separate storage devices or in separate partitions of the same storage device. In such systems a menu at startup gives a choice of which OS to boot/start (and only one OS at a time is loaded).
When the medium (or media, when the filesystem is a volume filesystem as in RAID arrays) is mounted, these metadata are read by the operating system so that it can use the storage. [2] [3] Unix-like operating systems often include software and tools that assist in the mounting process and provide it new functionality. Some of these strategies ...
