@node PowerPC System emulator
@section PowerPC System emulator
Use the executable @file{qemu-system-ppc} to simulate a complete 40P (PREP)
or PowerMac PowerPC system.
QEMU emulates the following PowerMac peripherals:
@itemize @minus
@item
UniNorth or Grackle PCI Bridge
@item
PCI VGA compatible card with VESA Bochs Extensions
@item
2 PMAC IDE interfaces with hard disk and CD-ROM support
@item
NE2000 PCI adapters
@item
Non Volatile RAM
@item
VIA-CUDA with ADB keyboard and mouse.
@end itemize

Since version 0.9.1, QEMU uses OpenBIOS @url{https://www.openbios.org/}
for the g3beige and mac99 PowerMac and the 40p 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.
@c man begin OPTIONS
The following options are specific to the PowerPC emulation:
@table @option
@item -g @var{W}x@var{H}[x@var{DEPTH}]
Set the initial VGA graphic mode. The default is 800x600x32.
@item -prom-env @var{string}
Set OpenBIOS variables in NVRAM, for example:
@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'
@end example
@end table
@c man end
