PowerPC System emulator¶

system emulation (PowerPC)

Use the executable qemu-system-ppc to simulate a complete PREP or PowerMac PowerPC system.

QEMU emulates the following PowerMac peripherals:

UniNorth or Grackle PCI Bridge
PCI VGA compatible card with VESA Bochs Extensions
2 PMAC IDE interfaces with hard disk and CD-ROM support
NE2000 PCI adapters
Non Volatile RAM
VIA-CUDA with ADB keyboard and mouse.

QEMU emulates the following PREP peripherals:

PCI Bridge
PCI VGA compatible card with VESA Bochs Extensions
2 IDE interfaces with hard disk and CD-ROM support
Floppy disk
NE2000 network adapters
Serial port
PREP Non Volatile RAM
PC compatible keyboard and mouse.

QEMU uses the Open Hack’Ware Open Firmware Compatible BIOS available at http://perso.magic.fr/l_indien/OpenHackWare/index.htm.

Since version 0.9.1, QEMU uses OpenBIOS http://www.openbios.org/ for the g3beige and mac99 PowerMac machines. OpenBIOS is a free (GPL v2) portable firmware implementation. The goal is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) compliant firmware.

The following options are specific to the PowerPC emulation:

-g WxH[xDEPTH]

Set the initial VGA graphic mode. The default is 800x600x32.

-prom-env string

Set OpenBIOS variables in NVRAM, for example:

qemu-system-ppc -prom-env 'auto-boot?=false' \
 -prom-env 'boot-device=hd:2,\yaboot' \
 -prom-env 'boot-args=conf=hd:2,\yaboot.conf'

These variables are not used by Open Hack’Ware.
