OS is a family of proprietary native operating systems of the Amiga and Amiga. One personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1. Early versions of Amiga. OS required the Motorola 6. Later versions were developed by Haage Partner Amiga. OS 3. 5 and 3. 9 and then Hyperion Entertainment Amiga. OS 4. 0 4. 1. A Power. PC microprocessor is required for the most recent release, Amiga. OS 4. Amiga. OS is a single user operating system based on a preemptive multitaskingkernel, called Exec. It includes an abstraction of the Amigas hardware, a disk operating system called Amiga. DOS, a windowing system. API called Intuition and a desktop file manager called Workbench. The Amiga intellectual property is fragmented between Amiga Inc., Cloanto, and Hyperion Entertainment. The copyrights for works created up to 1. Cloanto. 12 In 2. Amiga Inc. contracted Amiga. OS 4 development to Hyperion Entertainment and, in 2. Hyperion an exclusive, perpetual, worldwide license to Amiga. OS 3. 1 in order to develop and market Amiga. OS 4 and subsequent versions. On December 2. Amiga. OS 3. 1 source codeleaked to the web this was confirmed by the rights holder, Hyperion Entertainment. ComponentseditAmiga. OS is a single user operating system based on a preemptive multitaskingkernel, called Exec. Amiga. OS provides an abstraction of the Amigas hardware, a disk operating system called Amiga. DOS, a windowing system. API called Intuition and a desktop file manager called Workbench. A command line interface CLI, called Amiga. Shell, is also integrated into the system, though it also is entirely window based. The CLI and Workbench components share the same privileges. Notably, Amiga. OS lacks any built in memory protection. Amiga. OS is formed from two parts, namely, a firmware component called Kickstart and a software portion usually referred to as Workbench. Up until Amiga. OS 3. Kickstart and Workbench were typically released together. However, since Amiga. OS 3. 5, the first release after Commodores demise, only the software component has been updated and the role of Kickstart has been diminished somewhat. Firmware updates may still be applied by patching at system boot. Firmware and bootloadereditKickstart is the bootstrap firmware, usually stored in ROM. Kickstart contains the code needed to boot standard Amiga hardware and many of the core components of Amiga. OS. The function of Kickstart is comparable to the BIOS plus the main operating system kernel in IBM PC compatibles. However, Kickstart provides more functionality available at boot time than would typically be expected on PC, for example, the full windowing environment. Kickstart contains many core parts of the Amigas operating system, such as Exec, Intuition, the core of Amiga. DOS and functionality to initialize Autoconfig compliant expansion hardware. Later versions of the Kickstart contained drivers for IDE and SCSI controllers, PC card ports and other built in hardware. Upon start up or reset the Kickstart performs a number of diagnostic and system checks and then initializes the Amiga chipset and some core OS components. It will then examine connected boot devices and attempt to boot from the one with the highest boot priority. Evangelion Episode 24 Raw 2011. If no boot device is present a screen will be displayed asking the user to insert a boot disk, typically a floppy disk. At start up Kickstart attempts to boot from a bootable device typically, a floppy disk or hard disk drive. In the case of a floppy, the system reads the first two sectors of the disk the bootblock, and executes any boot instructions stored there. Normally this code passes control back to the OS invoking Amiga. DOS and the GUI and using the disk as the system boot volume. Any such disk, regardless of the other contents of the disk, was referred to as a Boot disk or bootable disk. A bootblock could be added to a blank disk by use of the install command. Some entertainment software contained custom bootblocks. This allowed an application, game or demo to take control of memory and resources, effectively disabling Amiga. OS. The bootblock became an obvious target for virus writers. Some games or demos that used a custom bootblock would not work if infected with a bootblock virus, as the code of the virus replaced the original. The first such virus was the SCA virus. Anti virus attempts included custom bootblocks. These amended bootblock advertised the presence of the virus checker while checking the system for tell tale signs of memory resident viruses and then passed control back to the system. Unfortunately these could not be used on disks that already relied on a custom bootblock, but did alert users to potential trouble. Several of them also replicated themselves across other disks, becoming little more than viruses in their own right. The Macintosh should have had multitasking. I cant stress enough what a big contribution it makes to the elegant design of system software. The Amiga has an excellent multitasking system, and I think it will have twice the product life of the Macintosh because of it. Adam Brooks Webber, the programmer responsible for porting True. BASIC to the Amiga and Macintosh, Byte, September 1. Exec is the multi taskingkernel of Amiga. OS. Exec provides functionality for multi tasking, memory allocation, interrupt handling and handling of dynamic shared libraries. It acts as a scheduler for tasks running on the system, providing pre emptive multitasking with prioritized round robin scheduling. Exec also provides access to other libraries and high level inter process communication via message passing. Other comparable microkernels have had performance problems because of the need to copy messages between address spaces. Since the Amiga has only one address space, Exec message passing is quite efficient. Amiga. DOSeditAmiga. DOS provides the disk operating system portion of the Amiga. OS. This includes file systems, file and directory manipulation, the command line interface, file redirection, console windows, and so on. Its interfaces offer facilities such as command redirection, piping, scripting with structured programming primitives, and a system of global and local variables. In Amiga. OS 1. x, the Amiga. DOS portion was based on TRIPOS, which is written in BCPL. Interfacing with it from other languages proved a difficult and error prone task, and the port of TRIPOS was not very efficient. From Amiga. OS 2. Amiga. DOS was rewritten in C and Assembler, retaining 1. BCPL program compatibility, and it incorporated parts of the third party Amiga. DOS Resource Project,9 which had already written replacements for many of the BCPL utilities and interfaces. ARP also provided one of the first standardized file requesters for the Amiga, and introduced the use of more friendly UNIX style wildcard globbing functions in command line parameters. Other innovations were an improvement in the range of date formats accepted by commands and the facility to make a command resident, so that it only needs to be loaded into memory once and remains in memory to reduce the cost of loading in subsequent uses. In Amiga. OS 4. 0, the DOS abandoned the BCPL legacy completely and, starting from Amiga. OS 4. 1, it has been rewritten with full 6. File extensions are often used in Amiga. OS, but they are not mandatory and they are not handled specially by the DOS, being instead just a conventional part of the file names. Executable programs are recognized using a magic number. Graphical user interfaceeditThe native Amiga windowing system is called Intuition, which handles input from the keyboard and mouse and rendering of screens, windows and basic widgets. However, until Amiga.
