+@node PowerPC System emulator
+@section PowerPC System emulator
+@cindex system emulation (PowerPC)
+
+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.

+
+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
