| - The 1.x series of Amiga OS 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). Versions 1.1 consists mostly of bug fixes and, like version 1.0, was only distributed for the Amiga 1000, and entire OS came on a single floppy disk. The entire set of Amiga OS consists of three disks: Kickstart, Workbench and ABasic by MetaComCo. The Amiga1000 model needs 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 ROM. Kickstart disk was still necessary for Amiga1000 models, but it was no longer necessary for Amiga500 or 2000, but the users of these systems must change the ROMs (there were socketed) to change the kickstart version. AmigaOS 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" (the user interface portion of the operation system). The second disk was the Extras disk. AmigaOS set of disks was still three disks, due to abolition of Kickstart disk. Users of A1000 could ask a Commodore dealer to obtain one. The third disk was now AmigaBasic by Microsoft.
