I've never manaed to get MorphOS to install on my EFIKA from a USB pen... OpenFirmware just refuses to read them all (although MorphOS reads them fine once booted, so it's good to have the iso image on
).. I had to do my install over TFTP... I haven't installed the latest MorphOS yet, so I may write-up some instructions on how to do a TFTP based install.
