Apple DOS is the disk operating system for the Apple II computers from late 1978 through early 1983. It was superseded by ProDOS in 1983. Apple DOS has three major releases: DOS 3.1, DOS 3.2, and DOS 3.3; [2] each one of these three releases was followed by a second, minor "bug-fix" release, but only in the case of Apple DOS 3.2 did that minor release receive its own version number, Apple DOS ...
CP/M, [3] originally standing for Control Program/Monitor [4] and later Control Program for Microcomputers, [5] [6] [7] is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system [8] and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.
Its Warp loader is 25 times faster, but programs can only be loaded with a loader saved to disk when the cartridge is not present. Whereas the ARMK6 fastloader was compatible with most software, The Final Cartridge III was known to crash often, [ citation needed ] so programs had to be loaded in normal C64 mode, deactivating the cartridge ...
Part of the compiler's function is to link these files in such a way that the program can be executed by the hardware. Once compiled, the program can be saved as an object file and the loader (part of the operating system) can take this saved file and execute it as a process on the computer hardware. [59]
A related example is based on a loader for a Nicolet Instrument Corporation minicomputer of the 1970s, using the paper tape reader-punch unit on a Teletype Model 33 ASR teleprinter. The bytes of its second-stage loader are read from paper tape in reverse order. Set the P register to 106; Check paper tape reader ready; If not ready, jump to 2
UEFI requires the firmware and operating system loader (or kernel) to be size-matched; that is, a 64-bit UEFI firmware implementation can load only a 64-bit operating system (OS) boot loader or kernel (unless the CSM-based legacy boot is used) and the same applies to 32-bit.
DOS 3 or DOS-3 may refer to: . Kosmos 557 aka Salyut-3 or DOS-3, a Russian space station; Apple DOS for the Apple II series, released in versions 3.1, 3.2, and 3.3; Atari DOS 3 for the Atari 8-bit family
The intermediate stage loader (stage1.5, usually core.img) is loaded and executed by the stage1 loader. The second-stage loader (stage2, the /boot/grub/ files) is loaded by the stage1.5 and displays the GRUB startup menu that allows the user to choose an operating system or examine and edit startup parameters.
