Going back to my developer days:
Kickstart, the ROM Kernal (originally on Disk for the A1000) loaded through something called the Writeable Control Store. SuperKickstart was only on the original A3000 units, and allowed dual booting of 1.3 and 2.0 Workbench/Kickstart and used the A3000's 68030MMU to handle all of that. Kickstart was in ROM on the A500 A2000 and could be added to the A3000.
Workbench (the GUI and disk that boots AmigaDOS).. Workbench contains AmigaDOS and the files to load up Inutition (The GUI)...
I really didn't agree with the change to "AmigaOS" with stuff beyond Workbench 3.x it seemed like everyone was in a "LETS COPY MAC" mode with advertising and the move to PowerPC which I never saw as useful at that stage of things anyway.. Especially since Commodore's next machine would have been based on PA RISC.
