sorry to ask but is there somewhere a list of the following available:

• list of available kernels & download
• list of available linux images or live dvds
• most important: a description how to boot/start/install the (different) kernels and images

can we maybe make this a sticky topic here in the board?

from time to time i'm in the mood to test a linux version here on my x1000 but - well- every time i have no clue again how to do it.

thanks and regards
michael

You can find all the kernels, images, and ISOs on the following website: http://www.supertuxkart-amiga.de/amiga/x1000.html#downloads. You can test our ubuntu MATE 16.04 live DVD if you like.

Download: vmlinux-4.15-rc2-AmigaOne_X1000_X5000.tar.gz

Please test it.

so are the other images, like the opensus ones (http://www.supertuxkart-amiga.de/amiga/ ... nsuse.html) no "live" dvds? only usefull for installation? i thought theses days all of the linux distros can be run out of the box for testing? just to understand.

How can I do it? Unfortunately I am not the admin here.
