| ========================================================= |
| 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. |
| |
| Genesi/bPlan Pegasos II (``pegasos2``) |
| ====================================== |
| |
| The ``pegasos2`` machine emulates the Pegasos II sold by Genesi and |
| designed by bPlan. Its schematics are available at |
| https://www.powerdeveloper.org/platforms/pegasos/schematics. |
| |
| Emulated devices |
| ---------------- |
| |
| * PowerPC 7457 CPU (can also use ``-cpu g3`` or ``750cxe``) |
| * Marvell MV64361 Discovery II north bridge |
| * VIA VT8231 south bridge |
| * PCI VGA compatible card (guests may need other card instead) |
| * PS/2 keyboard and mouse |
| |
| Firmware |
| -------- |
| |
| The Pegasos II board has an Open Firmware compliant ROM based on |
| SmartFirmware with some changes that are not open-sourced therefore |
| the ROM binary cannot be included in QEMU. An updater was available |
| from bPlan, it can be found in the `Internet Archive |
| <http://web.archive.org/web/20071021223056/http://www.bplan-gmbh.de/up050404/up050404>`_. |
| The ROM image can be extracted from it with the following command: |
| |
| .. code-block:: bash |
| |
| $ tail -c +85581 up050404 | head -c 524288 > pegasos2.rom |
| |
| Running Linux |
| ------------- |
| |
| The PowerPC version of Debian 8.11 supported Pegasos II. The BIOS |
| emulator in the firmware binary is unable to run QEMU‘s standard |
| vgabios so it needs to be disabled. To boot the system run: |
| |
| .. code-block:: bash |
| |
| $ qemu-system-ppc -machine pegasos2 -bios pegasos2.rom \ |
| -cdrom debian-8.11.0-powerpc-netinst.iso \ |
| -device VGA,romfile="" -serial stdio |
| |
| At the firmware ``ok`` prompt enter ``boot cd install/pegasos``. |
| |
| Alternatively, it is possible to boot the kernel directly without |
| firmware ROM using the QEMU built-in minimal Virtual Open Firmware |
| (VOF) emulation which is also supported on ``pegasos2``. For this, |
| extract the kernel ``install/powerpc/vmlinuz-chrp.initrd`` from the CD |
| image, then run: |
| |
| .. code-block:: bash |
| |
| $ qemu-system-ppc -machine pegasos2 -serial stdio \ |
| -kernel vmlinuz-chrp.initrd -append "---" \ |
| -cdrom debian-8.11.0-powerpc-netinst.iso |
| |
| aCube Sam460ex (``sam460ex``) |
| ============================= |
| |
| The ``sam460ex`` machine emulates the Sam460ex board by aCube which is |
| based on the AMCC PowerPC 460EX SoC (that despite its name has a |
| PPC440 CPU core). |
| |
| Firmware |
| -------- |
| |
| The board has a firmware based on an older U-Boot version with |
| modifications to support booting AmigaOS 4. The firmware ROM is |
| included with QEMU. |
| |
| Emulated devices |
| ---------------- |
| |
| * PowerPC 460EX SoC |
| * M41T80 serial RTC chip |
| * Silicon Motion SM501 display parts (identical to SM502 on real board) |
| * Silicon Image SiI3112 2 port SATA controller |
| * USB keyboard and mouse |
| |
| Running Linux |
| ------------- |
| |
| The only Linux distro that supported Sam460ex out of box was CruxPPC |
| 2.x. It can be booted by running: |
| |
| .. code-block:: bash |
| |
| $ qemu-system-ppc -machine sam460ex -serial stdio \ |
| -drive if=none,id=cd,format=raw,file=crux-ppc-2.7a.iso \ |
| -device ide-cd,drive=cd,bus=ide.1 |
| |
| There are some other kernels and instructions for booting other |
| distros on aCube's product page at |
| https://www.acube-systems.biz/index.php?page=hardware&pid=5 |
| but those are untested. |
