 In order to launch a Linux process, QEMU needs the process executable
-itself and all the target (x86) dynamic libraries used by it. Currently,
-QEMU is not distributed with the necessary packages so that you can test
-it easily on non x86 CPUs.
+itself and all the target (x86) dynamic libraries used by it. 
+
+@itemize
 
-However, the statically x86 binary 'tests/hello' can be used to do a
-first test:
+@item On x86, you can just try to launch any process by using the native
+libraries:
 
 @example 
-qemu tests/hello
+qemu -L / /bin/ls
 @end example
 
-@code{Hello world} should be printed on the terminal.
+@code{-L /} tells that the x86 dynamic linker must be searched with a
+@file{/} prefix.
 
-If you are testing it on a x86 CPU, then you can test it on any process:
 
-@example 
-qemu /bin/ls -l
+@item On non x86 CPUs, you need first to download at least an x86 glibc
+(@file{qemu-i386-glibc21.tar.gz} on the QEMU web page). Then you can
+launch the precompiled @file{ls} x86 executable:
+@example
+qemu /usr/local/qemu-i386/bin/ls
+@end example
+You can look at @file{/usr/local/qemu-i386/bin/qemu-conf.sh} so that QEMU is automatically
+launched by the Linux kernel when you try to launch x86 executables. It
+requires the @code{binfmt_misc} module in the Linux kernel.
