AMIGA OS 3.9 BOOT DISK INSTALL

A bootblock could be added to a blank disk by use of the install command. Any such disk, regardless of the other contents of the disk, was referred to as a "Boot disk" or "bootable disk". Normally this code passes control back to the OS (invoking AmigaDOS and the GUI) and using the disk as the system boot volume. 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. If no boot device is present a screen will be displayed asking the user to insert a boot disk, typically a floppy disk.Īt start-up Kickstart attempts to boot from a bootable device (typically, a floppy disk or hard disk drive). It will then examine connected boot devices and attempt to boot from the one with the highest boot priority. 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.

Later versions of the Kickstart contained drivers for IDE and SCSI controllers, PC card ports and other built-in hardware. Kickstart contains many core parts of the Amiga's operating system, such as Exec, Intuition, the core of AmigaDOS and functionality to initialize Autoconfig-compliant expansion hardware.

However, Kickstart provides more functionality available at boot time than would typically be expected on PC, for example, the full windowing environment. The function of Kickstart is comparable to the BIOS plus the main operating system kernel in IBM PC compatibles. Kickstart contains the code needed to boot standard Amiga hardware and many of the core components of AmigaOS.

Kickstart is the bootstrap firmware, usually stored in ROM. That was until 2018 when Hyperion Entertainment (license holder to AmigaOS 3.1) released AmigaOS 3.1.4 with an updated Kickstart ROM to go with it. Firmware updates may still be applied by patching at system boot.

However, since AmigaOS 3.5, the first release after Commodore's demise, only the software component has been updated and the role of Kickstart has been diminished somewhat. Up until AmigaOS 3.1, matching versions of Kickstart and Workbench were typically released together. Notably, AmigaOS lacks any built-in memory protection.ĪmigaOS is formed from two parts, namely, a firmware component called Kickstart and a software portion usually referred to as Workbench. The CLI and Workbench components share the same privileges. AmigaOS provides an abstraction of the Amiga's hardware, a disk operating system called AmigaDOS, a windowing system API called Intuition and a desktop file manager called Workbench.Ī command-line interface (CLI), called AmigaShell, is also integrated into the system, though it also is entirely window-based. 3.3 Memory paging and a swap partition in later versionsĪmigaOS is a single-user operating system based on a preemptive multitasking kernel, called Exec.On December 29, 2015, the AmigaOS 3.1 source code leaked to the web this was confirmed by the licensee, Hyperion Entertainment. contracted AmigaOS 4 development to Hyperion Entertainment and, in 2009 they granted Hyperion an exclusive, perpetual, worldwide license to AmigaOS 3.1 in order to develop and market AmigaOS 4 and subsequent versions. The copyrights for works created up to 1993 are owned by Cloanto. The Amiga intellectual property is fragmented between Amiga Inc., Cloanto, and Hyperion Entertainment. It includes an abstraction of the Amiga's hardware, a disk operating system called AmigaDOS, a windowing system API called Intuition and a desktop file manager called Workbench. A PowerPC microprocessor is required for the most recent release, AmigaOS 4.ĪmigaOS is a single-user operating system based on a preemptive multitasking kernel, called Exec. Later versions were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985.
