the QEMU handbook for a one stop solution.

+AmigaNG boards (``amigaone``, ``pegasos2``, ``sam460ex``)
+=========================================================
+
+These PowerPC machines emulate boards that are primarily used for
+running Amiga like OSes (AmigaOS 4, MorphOS and AROS) but these can
+also run Linux which is what this section documents.
+
+Eyetech AmigaOne/Mai Logic Teron (``amigaone``)
+===============================================
+
+The ``amigaone`` machine emulates an AmigaOne XE mainboard by Eyetech
+which is a rebranded Mai Logic Teron board with modified U-Boot
+firmware to support AmigaOS 4.
+
+Emulated devices
+----------------
+
+ * PowerPC 7457 CPU (can also use``-cpu g3, 750cxe, 750fx`` or ``750gx``)
+ * Articia S north bridge
+ * VIA VT82C686B south bridge
+ * PCI VGA compatible card (guests may need other card instead)
+ * PS/2 keyboard and mouse
+
+Firmware
+--------
+
+A firmware binary is necessary for the boot process. It is a modified
+U-Boot under GPL but its source is lost so it cannot be included in
+QEMU. A binary is available at
+https://www.hyperion-entertainment.com/index.php/downloads?view=files&parent=28.
+The ROM image is in the last 512kB which can be extracted with the
+following command:
+
+.. code-block:: bash
+
+ $ tail -c 524288 updater.image > u-boot-amigaone.bin
+
+The BIOS emulator in the firmware is unable to run QEMU‘s standard
+vgabios so ``VGABIOS-lgpl-latest.bin`` is needed instead which can be
+downloaded from http://www.nongnu.org/vgabios.
+
+Running Linux
+-------------
+
+There are some Linux images under the following link that work on the
+``amigaone`` machine:
+https://sourceforge.net/projects/amigaone-linux/files/debian-installer/.
+To boot the system run:
+
+.. code-block:: bash
+
+ $ qemu-system-ppc -machine amigaone -bios u-boot-amigaone.bin \
+ -cdrom "A1 Linux Net Installer.iso" \
+ -device ati-vga,model=rv100,romfile=VGABIOS-lgpl-latest.bin
+
+From the firmware menu that appears select ``Boot sequence`` →
+``Amiga Multiboot Options`` and set ``Boot device 1`` to
+``Onboard VIA IDE CDROM``. Then hit escape until the main screen appears again,
+hit escape once more and from the exit menu that appears select either
+``Save settings and exit`` or ``Use settings for this session only``. It may
+take a long time loading the kernel into memory but eventually it boots and the
+installer becomes visible. The ``ati-vga`` RV100 emulation is not
+complete yet so only frame buffer works, DRM and 3D is not available.
