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. 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. Kickstart Amiga Wikipedia. Kickstart is the bootstrapfirmware of the Amiga computers developed by Commodore. Most Amiga models were shipped with the Kickstart firmware stored on ROM chips. Its purpose is to initialize the Amiga hardware and core components of Amiga. OS and then attempt to boot from a bootablevolume, such as a floppy disk. Versionsedit. The default boot screen displayed under Kickstart 1. Commodores Amiga. OS was formed of both the Kickstart firmware and a software component provided on disk with the software portion often termed as Workbench. For most Amiga. OS updates the Kickstart version number was matched to the Workbench version number. Confusingly, Commodore also used internal revision numbers for Kickstart chips. For example, there were several Kickstart revisions designated as version 2. Version summaryeditKickstart version. V number. Retailed with Amiga models. Launch date. ROM capacity.

Some A1. 00. 0 software titles notably Dragons Lair provided an alternative code base in order to use the extra 2. KB for data. Later Amiga models had Kickstart embedded in a ROM chip, thus improving boot times. Many Amiga 1. 00. Kickstart was stored in 2. KB ROM chips for releases prior to Amiga. OS 2. 0. Later releases used 5. KB ROM chips containing additional and improved functionality. The Amiga CD3. 2 featured a 1 MB ROM Kickstart 3. CD ROM. Early A3. A1. 00. 0, also shipped with Kickstart on floppy disk, and used a 1. BETA ROM as bootstrap. Either Kickstart 1. WB1. 3 or WB2. x, respectively, and put in DEVS kickstart, an absolute system location from where the A3. RAM. This early A3. ROM based Kickstarts and disk based Kickstarts, although not simultaneously. An A3. 00. 0 configured to use disk based Kickstart images had the benefit of being able to boot various versions of Amiga. OS without additional tools, simply by selecting the appropriate Kickstart image at boot time. The Commodore CDTV featured additional firmware ROMs which are not technically part of the Amiga Kickstart. The CDTVs original firmware ROMs must be upgraded in order to install a Kickstart version later than 1. Amiga. OS 2. 1 was a pure software update and did not require matching Kickstart ROM chips. Workbench 2. 1 ran on all Kickstart ROMs of the 2. Later releases of Amiga. OS 3. 5 and 3. 9 were also software only and did not include matching ROM upgrades instead requiring Kickstart 3. ROM file based Kickstart components replacing those in ROM. Kickstart modules of Amiga. OS 4 are stored on the boot disk partition. Up to Kickstart v. V3. 6 only 5. 12 byte blocks were supported. Motorola 6. 80. 40 uses write caches that requires the use of the functions Cache. Clear. U and Cache. Control to flush cache when program code has been modified. These functions are only available in Kickstart 2. FunctioneditThe default boot screen displayed under Kickstart 2. 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 check for connected boot devices and attempt to boot from the one with the highest boot priority. If no boot device is present a screen will be displayed asking the user to insert a boot disk  typically a floppy disk. Insertion of such a bootable disk other than workbench like disk will result in a a command line interface CLI prompt to operate with ROM internal and disks commands including programs, scripts if the disk is non workbench, or empty, orb a basic point and click UI named Workbench if the disk contains at least loadwb in the startup sequence script residing inside the s folder on this disk. OS alive in the background. Exec multitasking, driver initialization etc. The Kickstart contains many of the core components of the Amigas operating system, such as Exec the Amigas multi tasking kernel. Intuition functionality for GUI, screens, windowing and handling of inputoutput devices. Autoconfig functionality to automatically initialize or boot from compliant expansion hardware. Floppy disk device driver and file system to read and boot from floppy disk. DOS library for file access and handling. Amiga. DOS Command Line Interface CLI functionality and a number of core CLI commands. Graphics library for basic drawing and raster graphics functions using the native Amiga chipset. Audio device driver for the native Amiga sound hardware. Device drivers for the Amiga keyboard and mousegameports. Kickstart 1. 3 is the first version to support booting from a hard disk drive. From Amiga. OS release 2. Kickstart also contained device drivers to boot from devices on IDE controllers, support for PC Card ports and various other hardware built into Amiga models. Diagnostic testeditThe screen color after power on shows the result of the self test. If everything is working the following screen color sequence will be displayed Dark grey Hardware working and the registers are readable. Light grey ROM verified. White Initialization is alright. Ready to boot. 3. These colors indicate a problem The keyboard LED uses blink codes where One blink means the keyboard ROM has a checksum error3. Two blinks means RAM failure3. Three blinks means watchdog timer failure. When the Caps Lock key is repeatedly pressed approx. Caps Lock LED turning on and off each time indicates the CPU is correctly reading the CIAs. If the Caps Lock LED sticks on or off, the CPU is not servicing CIA interrupt requests. In general, to run a specific Workbench version a Kickstart with a matching or greater version number is required. It is not generally possible to boot directly into the Workbench windowing environment from Kickstart alone. Though much of the functionality required for Workbench is contained in Kickstart some disk based components are needed to launch it. From release 2. 0 onwards it is possible to enter a boot menu by holding down both mouse buttons at power on or reset. This allows the user to choose a boot device, set parameters for backwards compatibility and examine Autoconfig hardware. With third party software, it is possible to use an alternate Kickstart to the version stored in the embedded ROM chip. Such software allows a Kickstart version to be loaded from file into RAM  for example Kickstart 1. Kickstart 2. 0 or later.
