From: BALATON Zoltan <bala...@eik.bme.hu> Documentation on how to run Linux on the amigaone, pegasos2 and sam460ex machines is currently buried in the depths of the qemu-devel mailing list and in the source code. Let's collect the information in the QEMU handbook for a one stop solution.

It may +take a long time loading the kernel into memory but eventually it boots and the +installer becomes visible.
