Hidden messages:
  1. Maria Engström shares the following easter egg in the UBoot (ROM/BIOS) of the AmigaOne computers that run AmigaOS4 (therefore not really in Workbench itself). You can activate it by typing in the following on the UBoot prompt (] is the prompt symbol):
    ] setenv easteregg 1
    ] saveenv
    ] reboot
    

    The next time the AmigaOne computer is rebooted, the screen will look the startup-screen of a Commodore 64. Deactivating the easter egg is done by typing:

    ] setenv easteregg
    ] saveenv
    ] setenv x86_mode
    ] setenv vga_fg_color 7
    ] setenv vga_bg_color 0
    ] saveenv
    

    The colors after vga_XX_color can be combined from a palette of 16 colors and they are the same as the standard ANSI palette.

Media Information: One CD-ROM
Notes/comments:
  1. Chris Young notes that AmigaOS 4.0 "developer pre-release" edition for AmigaOne was released on June 2, 2004. He adds that, in a similar way to the A1000, and (to a lesser extent) early 2.x releases on the A3000, the ROM does not contain any part of AmigaOS and merely loads Kickstart from disk.
