(September 2010) () is the proprietary native of the personal computer. Since its introduction with the launch of the in 1985, there have been four major versions and several minor revisions of the operating system. Initially the Amiga operating system had no strong name and branding, as it was simply considered an integral part of the Amiga system as a whole. Early names used for the Amiga operating system included 'CAOS' and 'AmigaDOS'. Another non-official name was 'Workbench', from the name of the Amiga, which was included on a floppy disk named 'Amiga Workbench'.

Other filesystems. 9.1 ADFS - Acorn Disc File System. The Acorn Disc Filing System is the standard filesystem of the RiscOS operating system which runs on Acorn's ARM-based Risc PC. The Fast File System (FFS) is the common filesystem used on hard disks by Amiga(tm) systems since AmigaOS Version 1.3 (34.20). Bill McEwen announces Amiga OS 3.9, and talks about the future of both the Classic Amiga OS and the Amiga Digital Environment. October 2000.

Version 3.1 of the Amiga operating system was the first version to be officially referred to as 'Amiga OS' (with a space between 'Amiga' and 'OS') by Commodore. Version 4.

What many consider the first versions of AmigaOS (Workbench 1.0 up to 3.0) are here indicated with the Workbench name of their original disks. Workbench 1.0 Workbench 1.0 was released for the first time in October 1985. X series of Workbench defaults to a distinctive blue and orange color scheme, designed to give high contrast on even the worst of television screens (the colors can be changed by the user). Version 1.1 consists mostly of bug fixes and, like version 1.0, was distributed only for the. The entire Workbench operating system consisted of three floppy disks: Kickstart, Workbench and ABasic.

The Amiga 1000 needed a Kickstart disk to be inserted into floppy drive to boot up. An image of a simple illustration of a hand on a white screen, holding a blue Kickstart floppy, invited the user to perform this operation. After the kickstart was loaded into a special section of memory called the writable control store (WCS), the image of the hand appeared again, this time inviting the user to insert the Workbench disk.

Workbench version 1.2 was the first to support Kickstart stored in a. A Kickstart disk was still necessary for Amiga 1000 models; it was no longer necessary for Amiga 500 or 2000, but the users of these systems had to change the ROMs (which were socketed) to change the Kickstart version. Workbench now spanned two floppy disks, and supported installing and booting from hard drive (assuming the Amiga was equipped with one), the name of the main disk was still named 'Workbench' (which is also the user interface portion of the operating system). The second disk was the Extras disk. The system now shipped with by, the only software Microsoft ever wrote for the Amiga.

Kickstart version 1.2 corrected various flaws and added support. AutoConfig is a protocol similar to and is the predecessor of, in that it can configure expansion boards without user intervention. Kickstart version 1.3 improved little on its predecessor, the most notable change being auto booting from hard drives. Workbench 1.3, on the other hand, users can find several significant improvements to Workbench, including a faster file system for hard disks storage which resolved the problem of which wasted too much hard disk space due to the fact it could store only 488 bytes in any block of 512 bytes keeping 24 bytes for checksums.

Many improvements were made to the CLI (command line interface) of Amiga which was now a complete text based Shell, named AmigaShell, and various additional tools and programs. Kickstart/Workbench 1.4 [ ] Kickstart/Workbench 1.4 was a version of the upcoming 2.0 update and never released, but the Kickstart part was shipped in very small quantities with early computers, where it is often referred to as the ' ROM'. In these machines it is only used to bootstrap the machine and load the Kickstart that will be used to actually boot the system. The appearance of a very early first release of 1.4 was similar to 1.3, but with colors slightly changed.

A second version was similar to that of 2.0 and higher, with just minor differences. It is, however, possible to dump out of the OS selection screen by clicking where one would expect to see a close gadget. This will cause the machine to boot Kickstart 1.4 using either the wb_2.x: partition, or from a floppy. Workbench 2.0, 2.04, 2.05, 2.1 [ ].

Workbench 2.0 Workbench 2.0 was released in 1990 and introduced a lot of improvements and major advances to the GUI of the overall Amiga operating system. The harsh blue and orange colour scheme was replaced with a much easier on the eye grey and light blue with 3D aspect in the border of the windows. The Workbench was no longer tied to the 640×256 (PAL) or 640×200 (NTSC) display modes, and much of the system was improved with an eye to making future expansion easier. For the first time, a standardised 'look and feel' was added. This was done by creating the Amiga Style Guide, and including libraries and software which assisted developers in making conformant software. Technologies included the GUI element creation library gadtools, the software installation scripting language Installer, and the AmigaGuide hypertext help system.

Workbench 2.04 introduced ARexx, a system-wide scripting language. Programmers could add so-called 'ARexx ports' to their programs, which allowed them to be controlled from ARexx scripts. Using ARexx, you could make two completely different programs from different vendors work together seamlessly. For example, you could batch-convert a directory of files to thumbnail images with an ARexx-capable image-manipulation program, create and index HTML table of the thumbnails linking to the original images, and display it in a web browser, all from one script. ARexx became very popular, and was widely adopted by programmers. The AmigaDOS, previously written in and very difficult to develop for beyond basic file manipulation, was mostly rewritten in.

Unfortunately, some badly written software – especially games – failed to run with 2.x, and so a lot of people were upset with this update. Most often, the failure occurred because programmers had used directly manipulated private structures maintained by the operating system, rather than using official function calls. Many users circumvented the problem by installing so-called 'kickstart switchers', a small circuit board which held both a Kickstart 1.3 and 2.0 chip, with which they could swap between Kickstart versions at the flick of a switch. 2.x shipped with the A500+ (2.04), A600 (2.05), A3000 and A3000T. Workbench 2.1 was the last in this series, and only released as a software update. It included useful features such as, to support working with floppy disks formatted for. Since 2.1 was a software-only release, there was no Kickstart 2.1 ROM.

2.x also introduced PCMCIA card support, for the slot on the A600. Workbench 2.1 introduced also a standard hypertext markup language for easily building guides for the user or help files, or manuals.

It was called. Release 2.1 was also the first Workbench release to feature a system-standard localization system, allowing the user to make an ordered list of preferred languages; when a locale-aware application runs, it asks the operating system to find the catalog (a file containing translations of the application's strings) best matching the user's preferences. AmigaOS 3.0, 3.1 [ ]. Amiga Workbench 3 Workbench 3.0 was released in 1992 and version 3.1 between 1993 (for the ) and 1994 (for other Amiga models).

Version 3.1 is the last AmigaOS released by Commodore. The 3.x series added support for new Amiga models. Other new features included: • A universal data system, known as DataTypes, that allowed programs to load pictures, sound, text and other content in formats they didn't understand directly, through the use of standard plugs ( see ) • Better color remapping for high-color display modes and support for new chipset • Improved visual appearance for Workbench desktop • CD-ROM support as required for (3.1) 3.x shipped with the,, and. AmigaOS 3.5, 3.9 [ ]. TCP/IP stacks After the demise of Commodore, Workbench 3.5 was released on 18 October 1999 and 3.9 in December 2000 by company, which was granted the license to update the Amiga operating system by its new owners. Whereas all previous OS releases ran on new release 3.5 onwards required a or better, CD-ROM and at least 4 MB RAM. Unlike previous releases 3.5 was released on a CD-ROM.

The Kickstart 3.1 was also required as the operating system didn't include new ROM. Updates included: • • Supplied with stack (unregistered time-limited free MiamiDX demo in 3.5, unrestricted AmiTCP in 3.9), web browser (AWeb), and e-mail client • Improved GUI and new toolkit called 'ReAction' • AVI/MPEG movie player (OS3.9) • New partitioning software to support hard disks larger than 4 GB • HTML documentation in English and German • MP3 and CD audio player (OS3.9) • Dock program (OS3.9) • Improved Workbench with asynchronous features • Find utility (OS3.9) • Unarchiving system called (OS3.9) • kernel to support accelerator boards AmigaOS 4 [ ]. AmigaOS 4.0 GUI: Workbench 4.0 A new version of AmigaOS was released on December 24, 2006 after five years of development by () under license from.

For registered users. During the five years of development, users of machines could download from Hyperion repository Pre-Release Versions of AmigaOS 4.0 as long as these were made available. As witnessed by many users into Amiga discussion forum sites, these versions were stable and reliable, despite the fact that they are technically labeled as 'pre-releases'. Last stable version of AmigaOS 4.0 for AmigaOne computers is the 'July 2007 Update', released for download 18 July 2007 to the registered users of AmigaOne machines. AmigaOS 4 Classic was released commercially for older Amiga computers with CyberstormPPC and BlizzardPPC accelerator cards in November 2007. It had previously been available only to developers and beta-testers.

Version 4.0 [ ] The new version is -native, finally abandoning the. AmigaOS 4.0 will run on some hardware, which currently only includes, and with PowerPC accelerator boards and motherboards.

S distribution policies for AmigaOS 4.0 and any later versions require that for third-party hardware the OS must be bundled with it, with the sole exception of Amigas with Phase 5 PowerPC accelerator boards, for which the OS will be sold separately. AmigaOS 4.0 Final introduced a new memory system based on the. Features, among others: • Fully skinnable GUI • Virtualized memory • Integrated viewer for PDF and other document formats • Support for PowerPC (native) and 68k (interpreted/JIT) applications • New drivers for various hardware • New memory allocation system • Support for file sizes larger than 2 GB • Integrated 2D Graphics API • Integrated 3D Graphics API Version 4.1 [ ]. AmigaOS 4.1 GUI: Workbench 4.1 AmigaOS 4.1 was presented to the public July 11, 2008, and went on sale September 2008. This is a new version and not only a simple update as it features, among others: • Memory paging • filesystem with the support for drives and partitions of multiple terabyte size • Hardware compositing engine ( R1xx and R2xx family) • Implementation of the device-independent 2D rendering library • New and improved DOS functionality (full 64 bit support, universal notification support, automatic expunge and reload of updated disk resources) • Improved 3D hardware accelerated screen-dragging See also [ ].

Alternatives to the AmigaOS 3.9 CD Alternatives to the AmigaOS 3.9 CD Introduction This tutorial explains some alternative methods of making it possible to install AmigaOS 3.9 on a real Amiga by using the Emergency Disk II boot floppy, and it's mainly intended for those who doesn't have a CD-ROM drive connected to their Amiga. The tutorial is really not completely finished yet, among other things, it will in the future include some instructions on how to make a customized AmigaOS 3.9 ISO image. Let's start off by debunking a couple of myths that seems to be floating around: Myth 1: The AmigaOS 3.9 CD contains copy protection. This is not true, and I belive there are two reasons why some people seem to think so.

The first one is the fact that although it's possible to browse the CD on a Windows PC, there will be problems when trying to copy all files from it. But what causes this isn't copy protection, no it's quite simply because Windows doesn't 100% support the file system used on the CD (there are problems with international characters in the file names for example). The second reason has to do with the Boing Bag updates.

Upon installing them, the installer will ask the user to insert the AmigaOS 3.9 CD, and then it will try to verify if it's a genuine CD by simply checking for the presence of certain files on it. One example of the files that will be checked, is the AmigaOS3.9:Videos/Angels.avi file, and if it's missing, the installer will complain. Myth 2: You need the AmigaOS 3.9 CD for installing AmigaOS 3.9.

This is not entirely true, because what you need is the contents of the CD, and a way for the Emergency Disk and the various installers to find this content. This basically means that the AmigaOS 3.9 files can be on any storage device. Below you will find various solutions as to how this can be arranged, so continue reading on.

Accessing the AmigaOS 3.9 CD via WinUAE As mentioned above, there are certain problems with trying to copy files from the AmigaOS 3.9 CD on a Windows PC, but it is possible to achive this by using an emulated Amiga. The instructions below describes how this can be done with WinUAE, but have in mind that I'm using version 2.3.1 of the program here, I don't know if it will work with earlier versions. First of all you need to insert the AmigaOS 3.9 CD into the CD/DVD drive of your PC. If you have plans of copying the contents of the CD over to a empty USB pendrive or Compact Flash card (to be used with a CF-PCMCIA adapter), you should insert this as well, just have in mind that it must have a capacity of at least 512MB. Take a note of the volume name of the USB drive/CF card since it will make it easier to identify later on, and if it doesn't have a name, I recommend that you give it one before you continue.

Now you can start WinUAE. I will not explain how to set up an emulated Amiga here, instead I will assume that you already have done this in the past. What you basically need is a bootable HDF image, but a Workbench ADF image file might work as well (like I did in the example below). Before you click the Start button in WinUAE, you should first click ' Hard drives' in the box to the left. Next, make sure that the ' Add PC drives at startup', ' Include removable drives.'

And ' Include CD/DVD drives.' Options are enabled. Continue with clicking the Start button. Please note the following: 1.

In case you are a little worried about giving the emulated Amiga access to all drives on your PC, have in mind that enabling the 'Add PC drives at startup' option may really not be necessary. As an alternative you can add a directory present on your PC instead. 2.Since Emergency Disk II floppies created with Amiga911 Maker 1.62 now supports booting from AmigaOS3.9 HDF images in addition to ISO, you may consider creating a hardfile and adding it to the emulated Amiga if you intend to later use E-Disk-II for installing OS3.9 on your real Amiga. Just make a new HDF file that's at least 512 MB big, so that all AmigaOS 3.9 files can be copied to it.

After the emulated Amiga has booted, you should be able to see the AmigaOS3.9 icon on the Workbench screen. Since WinUAE will treat the CD in the same way as if it was mounted on a real Amiga, you should now be able to copy the files from it without any errors. The easiest way to do this is probably by using a filemanager of some sort (like DOpus), but it can also of course be done in a Shell window.

Just remember that ALL files must be copied, this includes both the audio and video files. Below are some examples of what you can do next: 1. Copy the AmigaOS 3.9 files to a USB pendrive or CF card First you must try to locate your pendrive or CF card, if you did what I mentioned earlier about taking a note of the volume name, this shouldn't be a problem.

Otherwise you can try to locate the correct device by checking the capacity or contents of all the mounted drives on your emulated Amiga. When you have figured this out, you can either use a filemanager for copying all the files, or you can do it in Shell. In my case, the pendrive was called CORSAIR, so I entered the following in Shell: Copy AmigaOS3.9: to CORSAIR: ALL But here you must of course replace CORSAIR with the volume (or device) name of your own pendrive/CF card. After the copying is done, you can make an additional EXTRAS drawer for the Boing Bag updates, an and various other stuff that can be useful to have. This is best done from Workbench in order to give the drawer an icon (EXTRAS.info) Now there is one final thing to do, and that is to rename the pendrive/CF card. This has to be done from Windows, so quit WinUAE. It would really have been best to rename the pendrive/CF card to AmigaOS3.9, but here the problem is that FAT formatted drives can't have dots in the volume names, so you will have to rename the device to AmigaOS39 instead.

Don't worry about the drive not having the correct name since the Emergency Disk II floppy will look for both names upon booting. Copy the AmigaOS 3.9 files to a HDF image file With Amiga911 Maker 1.62 it is possible to create Emergency Disk II floppies that supports booting from both AmigaOS3.9 ISO and HDF image files, where they can be present on any drive that gets mounted upon booting the Emergency Disk II.

For doing this you must first create a new HDF image file in WinUAE, and then add it to the emulated Amiga. The HDF image needs to be at least 512 MB in size, and you should also make sure that the default settings with a block size of 512 bytes and a BlocksPerTrack value of 32 is used. Another thing is that it's safest to just use the standard FastFileSystem (FFS). After the emulated Amiga has booted up, you may need to format the HDF image. So click on the correct device icon, and select 'Icons >Format disk' from the Workbench menu. In the window that now pops up, make sure that only the 'Fast File System' and 'International Mode' options are enabled.

The Volume Name suggested should be 'Empty', and you can just leave this alone for now (you will rename it later). Now click the 'Quick Format' button in order to start formatting the HDF file. When this is done, you can copy all files from the AmigaOS3.9 CD to the HDF volume, so either use a filemanager or enter the following in Shell: Copy AmigaOS3.9: to Empty: ALL CLONE Since the copying is done to a volume with the native Amiga filesystem (FFS), the CLONE argument can be used in order to preserve all Amiga specific file attributes. When the copy process is finished, you can finally rename the volume name from Empty to AmigaOS3.9 by clicking the drive icon and selecting 'Icons >Rename' from the WB menu. Now you can just quit WinUAE and copy the HDF image file to whatever device to be used on the real Amiga. You will also have to configure the Emergency Disk II in order for it to use the HDF file for booting, some instructions for this can be found in the part of the tutorial.

Copy the AmigaOS 3.9 files to the harddisk of your PC You can also copy all files from the AmigaOS 3.9 CD directly to the harddisk of your PC. This can be useful if you need to do something with the files outside of WinUAE. One example can be if you can't get the USB pendrive or Compact Flash card to be properly mounted on the emulated Amiga. Then you can first copy the files from the AmigaOS 3.9 CD over to the harddisk, and then in Windows copy the files from the harddisk to the pendrive/CF card.

Another example is if you want to add all AmigaOS 3.9 files to a zip archive file, and then somehow transfer it to a real Amiga. Just have in mind that it's really a good idea to first make a folder on your PC's harddisk, and then copy all files into that folder. As an example, I made an AmigaOS3.9 folder on my KISS partition (drive D: in Windows), and then entered the following in Shell: Copy AmigaOS3.9: to KISS:AmigaOS3.9 ALL 4.

Activate an Emergency Disk II floppy Another thing you can do is activating a ready-made Emergency Disk II floppy, you can find download links for the ADF images on the page, and instructions for activating can be found on the page.
