@cyfm and Mozzerfan,

Thank you for your replies. I have followed the instructions, only the sd card in a reader, no other usb peripheral plugged. Then I have tried on the AmigaOne X5000, typed the 2 commands indicated by bigfoot and that booted. I think that your instructions should be present on the web site of the MorphOs Team in help section. I should also be present on MorphOs Library. i will also indicated them to Obligement, Daff will certainly write there a article about this new version of MorphOS and also update his article http://obligement.free.fr/articles/morphos310_installation.php , about installing MorphOs on any supported hardware.
