I am really using my AmigaONE a lot at the moment. Been away for a while, but now I am back... Unplugged the mac and all...
Something strange, though.
Ever since the final update my AmigaOne goes directly to the uboot prefs (Not in Workbench) when I turn it on. Then I have to exit and only then does it starts to load OS4.
At the UBoot prefs press Esc and select "enter UBoot shell". At the shell prompt enter printenv. Press cursor-down quickly to stop the scrolling list. Check if there is a variable called menuboot_delay and if it is set to 0.
If it is 0, enter setenv menuboot_delay 3 or any other number of seconds. Then enter saveenv and reset.
Now you should see a progress bar which allows you to enter the UBoot prefs by a key press. When the delay is over, it should boot without entering the menu.
I guess the easiest thing to do is to start the UBoot prefs program from Workbench (Prefs/UBoot) and change the "Boota" value to your liking (under the "Boot" tab). The value can also be changed if you enter the UBoot menu during startup, but I don't remember the exact location right now.
Everything is fine with Uboot now. I have a three seconds chance to enter the menu if I want.
Then it goes to a screen, where I can choose OS4. It counts down from 20 and then boots. I can just press enter and it boots right away.
Before the final update I could also choose OS4 - debug and one or two others. Now, I only have OS4, so it should be possible to bypass this selection.
I will post the thing you asked for tomorrow. I have a day off, so there will be plenty of time for the Amiga!
Right, that would be the bootdelay which is apparently set to 20 in your UBoot. You can just do a "setenv bootdelay 1" followed by a "saveenv" at the UBoot prompt, or you can mess about with prefs or menus if you prefer.
I guess you could also set it to 0 so you don't see the bootmenu at all, but I'd suggest keeping it at 1, as it is much easier if some day you should get the idea of creating another Kickstart configuration.
Mine is set to 3 (as is my menuboot_delay). But then I do have 8 choices in my bootmenu ...
