-@chapter QEMU PowerPC System emulator invocation
+@chapter QEMU System emulator for non PC targets
+
+QEMU is a generic emulator and it emulates many non PC
+machines. Most of the options are similar to the PC emulator. The
+differences are mentionned in the following sections.
+
+@section QEMU PowerPC System emulator
Use the executable @file{qemu-system-ppc} to simulate a complete PREP
or PowerMac PowerPC system.
@end itemize
QEMU uses the Open Hack'Ware Open Firmware Compatible BIOS available at
-@url{http://site.voila.fr/jmayer/OpenHackWare/index.htm}.
-
-You can read the qemu PC system emulation chapter to have more
-informations about QEMU usage.

+@url{http://perso.magic.fr/l_indien/qemu-ppc/}.
-@chapter Sparc32 System emulator invocation
+@section Sparc32 System emulator invocation
Use the executable @file{qemu-system-sparc} to simulate a JavaStation
(sun4m architecture). The emulation is somewhat complete.
@c man end
-@chapter Sparc64 System emulator invocation
+@section Sparc64 System emulator invocation
Use the executable @file{qemu-system-sparc64} to simulate a Sun4u machine.
The emulator is not usable for anything yet.
PC-compatible serial ports
@end itemize
-@chapter MIPS System emulator invocation
+@section MIPS System emulator invocation
Use the executable @file{qemu-system-mips} to simulate a MIPS machine.
-The emulator begins to launch a Linux kernel.
+The emulator is able to boot a Linux kernel and to run a Linux Debian
+installation from NFS. The following devices are emulated:
+
+@itemize @minus
+@item
+MIPS R4K CPU
+@item
+PC style serial port
+@item
+NE2000 network card
+@end itemize
+
+More information is available in the QEMU mailing-list archive.
+
+@section ARM System emulator invocation
+
+Use the executable @file{qemu-system-arm} to simulate a ARM
+machine. The ARM Integrator/CP board is emulated with the following
+devices:
+
+@itemize @minus
+@item
+ARM926E or ARM1026E CPU
+@item
+Two PL011 UARTs
+@item
+SMC 91c111 Ethernet adapter
+@end itemize
+
+A Linux 2.6 test image is available on the QEMU web site. More
+information is available in the QEMU mailing-list archive.
