1 ========================================================= 2 AmigaNG boards (``amigaone``, ``pegasos2``, ``sam460ex``) 3 ========================================================= 4 5 These PowerPC machines emulate boards that are primarily used for 6 running Amiga like OSes (AmigaOS 4, MorphOS and AROS) but these can 7 also run Linux which is what this section documents. 8 9 Eyetech AmigaOne/Mai Logic Teron (``amigaone``) 10 =============================================== 11 12 The ``amigaone`` machine emulates an AmigaOne XE mainboard by Eyetech 13 which is a rebranded Mai Logic Teron board with modified U-Boot 14 firmware to support AmigaOS 4. 15 16 Emulated devices 17 ---------------- 18 19 * PowerPC 7457 CPU (can also use ``-cpu g3, 750cxe, 750fx`` or ``750gx``) 20 * Articia S north bridge 21 * VIA VT82C686B south bridge 22 * PCI VGA compatible card (guests may need other card instead) 23 * PS/2 keyboard and mouse 24 25 Firmware 26 -------- 27 28 A firmware binary is necessary for the boot process. It is a modified 29 U-Boot under GPL but its source is lost so it cannot be included in 30 QEMU. A binary is available at 31 https://www.hyperion-entertainment.com/index.php/downloads?view=files&parent=28. 32 The ROM image is in the last 512kB which can be extracted with the 33 following command: 34 35 .. code-block:: bash 36 37 $ tail -c 524288 updater.image > u-boot-amigaone.bin 38 39 The BIOS emulator in the firmware is unable to run QEMU‘s standard 40 vgabios so ``VGABIOS-lgpl-latest.bin`` is needed instead which can be 41 downloaded from http://www.nongnu.org/vgabios. 42 43 Running Linux 44 ------------- 45 46 There are some Linux images under the following link that work on the 47 ``amigaone`` machine: 48 https://sourceforge.net/projects/amigaone-linux/files/debian-installer/. 49 To boot the system run: 50 51 .. code-block:: bash 52 53 $ qemu-system-ppc -machine amigaone -bios u-boot-amigaone.bin \ 54 -cdrom "A1 Linux Net Installer.iso" \ 55 -device ati-vga,model=rv100,romfile=VGABIOS-lgpl-latest.bin 56 57 From the firmware menu that appears select ``Boot sequence`` → 58 ``Amiga Multiboot Options`` and set ``Boot device 1`` to 59 ``Onboard VIA IDE CDROM``. Then hit escape until the main screen appears again, 60 hit escape once more and from the exit menu that appears select either 61 ``Save settings and exit`` or ``Use settings for this session only``. It may 62 take a long time loading the kernel into memory but eventually it boots and the 63 installer becomes visible. The ``ati-vga`` RV100 emulation is not 64 complete yet so only frame buffer works, DRM and 3D is not available. 65 66 Genesi/bPlan Pegasos II (``pegasos2``) 67 ====================================== 68 69 The ``pegasos2`` machine emulates the Pegasos II sold by Genesi and 70 designed by bPlan. Its schematics are available at 71 https://www.powerdeveloper.org/platforms/pegasos/schematics. 72 73 Emulated devices 74 ---------------- 75 76 * PowerPC 7457 CPU (can also use ``-cpu g3`` or ``750cxe``) 77 * Marvell MV64361 Discovery II north bridge 78 * VIA VT8231 south bridge 79 * PCI VGA compatible card (guests may need other card instead) 80 * PS/2 keyboard and mouse 81 82 Firmware 83 -------- 84 85 The Pegasos II board has an Open Firmware compliant ROM based on 86 SmartFirmware with some changes that are not open-sourced therefore 87 the ROM binary cannot be included in QEMU. An updater was available 88 from bPlan, it can be found in the `Internet Archive 89 <http://web.archive.org/web/20071021223056/http://www.bplan-gmbh.de/up050404/up050404>`_. 90 The ROM image can be extracted from it with the following command: 91 92 .. code-block:: bash 93 94 $ tail -c +85581 up050404 | head -c 524288 > pegasos2.rom 95 96 Running Linux 97 ------------- 98 99 The PowerPC version of Debian 8.11 supported Pegasos II. The BIOS 100 emulator in the firmware binary is unable to run QEMU‘s standard 101 vgabios so it needs to be disabled. To boot the system run: 102 103 .. code-block:: bash 104 105 $ qemu-system-ppc -machine pegasos2 -bios pegasos2.rom \ 106 -cdrom debian-8.11.0-powerpc-netinst.iso \ 107 -device VGA,romfile="" -serial stdio 108 109 At the firmware ``ok`` prompt enter ``boot cd install/pegasos``. 110 111 Alternatively, it is possible to boot the kernel directly without 112 firmware ROM using the QEMU built-in minimal Virtual Open Firmware 113 (VOF) emulation which is also supported on ``pegasos2``. For this, 114 extract the kernel ``install/powerpc/vmlinuz-chrp.initrd`` from the CD 115 image, then run: 116 117 .. code-block:: bash 118 119 $ qemu-system-ppc -machine pegasos2 -serial stdio \ 120 -kernel vmlinuz-chrp.initrd -append "---" \ 121 -cdrom debian-8.11.0-powerpc-netinst.iso 122 123 aCube Sam460ex (``sam460ex``) 124 ============================= 125 126 The ``sam460ex`` machine emulates the Sam460ex board by aCube which is 127 based on the AMCC PowerPC 460EX SoC (that despite its name has a 128 PPC440 CPU core). 129 130 Firmware 131 -------- 132 133 The board has a firmware based on an older U-Boot version with 134 modifications to support booting AmigaOS 4. The firmware ROM is 135 included with QEMU. 136 137 Emulated devices 138 ---------------- 139 140 * PowerPC 460EX SoC 141 * M41T80 serial RTC chip 142 * Silicon Motion SM501 display parts (identical to SM502 on real board) 143 * Silicon Image SiI3112 2 port SATA controller 144 * USB keyboard and mouse 145 146 Running Linux 147 ------------- 148 149 The only Linux distro that supported Sam460ex out of box was CruxPPC 150 2.x. It can be booted by running: 151 152 .. code-block:: bash 153 154 $ qemu-system-ppc -machine sam460ex -serial stdio \ 155 -drive if=none,id=cd,format=raw,file=crux-ppc-2.7a.iso \ 156 -device ide-cd,drive=cd,bus=ide.1 157 158 There are some other kernels and instructions for booting other 159 distros on aCube's product page at 160 https://www.acube-systems.biz/index.php?page=hardware&pid=5 161 but those are untested. 162
