1.. _PowerPC-System-emulator: 2 3PowerPC System emulator 4----------------------- 5 6Use the executable ``qemu-system-ppc`` to simulate a complete 40P (PREP) 7or PowerMac PowerPC system. 8 9QEMU emulates the following PowerMac peripherals: 10 11- UniNorth or Grackle PCI Bridge 12 13- PCI VGA compatible card with VESA Bochs Extensions 14 15- 2 PMAC IDE interfaces with hard disk and CD-ROM support 16 17- NE2000 PCI adapters 18 19- Non Volatile RAM 20 21- VIA-CUDA with ADB keyboard and mouse. 22 23QEMU emulates the following 40P (PREP) peripherals: 24 25- PCI Bridge 26 27- PCI VGA compatible card with VESA Bochs Extensions 28 29- 2 IDE interfaces with hard disk and CD-ROM support 30 31- Floppy disk 32 33- PCnet network adapters 34 35- Serial port 36 37- PREP Non Volatile RAM 38 39- PC compatible keyboard and mouse. 40 41Since version 0.9.1, QEMU uses OpenBIOS https://www.openbios.org/ for 42the g3beige and mac99 PowerMac and the 40p machines. OpenBIOS is a free 43(GPL v2) portable firmware implementation. The goal is to implement a 44100% IEEE 1275-1994 (referred to as Open Firmware) compliant firmware. 45 46The following options are specific to the PowerPC emulation: 47 48``-g WxH[xDEPTH]`` 49 Set the initial VGA graphic mode. The default is 800x600x32. 50 51``-prom-env string`` 52 Set OpenBIOS variables in NVRAM, for example: 53 54 :: 55 56 qemu-system-ppc -prom-env 'auto-boot?=false' \ 57 -prom-env 'boot-device=hd:2,\yaboot' \ 58 -prom-env 'boot-args=conf=hd:2,\yaboot.conf' 59 60More information is available at 61http://perso.magic.fr/l_indien/qemu-ppc/. 62
