+
+This are notes of how to perform the test.
+
+
+First of all you will need a i386 jail on amd64. This could be build like
+this:
+
+cat > jailbuild.sh <<EOF
+#!/bin/sh
+
+jail=/var/tmp/jail2 # Change this
+
+mount | grep $jail | grep -q devfs && umount $jail/dev
+
+here=`pwd`
+chflags -R 0 $jail
+rm -rf $jail
+mkdir -p $jail
+
+cd /var/tmp/deviant2 # You will need to change this!
+make -j4 TARGET=i386 TARGET_ARCH=i386 DESTDIR=$jail world
+make TARGET=i386 TARGET_ARCH=i386 DESTDIR=$jail distribution
+
+mount -t devfs devfs $jail/dev
+
+cp /etc/fstab /etc/hosts /etc/resolv.conf $jail/etc
+cp /boot/kernel/kernel $jail/boot/kernel
+EOF
+
+Before changing to the jail you may need these files:
+- Fetch the Firefox i386 installer. (http://www.mozilla.com)
+- Fetch a clip for a win32 codec:
+ ftp http://www.jhepple.com/support/SampleMovies/Real_Media.rm
+
+and place these in for examle $jail/root
+
+
+Chroot to /var/tmp/jail /bin/sh
+
+1) Install wine. For example by "UNAME_m=i386 pkg_add -r wine"
+3) Run wine on the Firefox installer.
+
+
+The mplayer test:
+
+It would seem that the default build of mplayer does not contain
+the i386 codec, so you have to build mplayer your self with option
+"Enable win32 codec set on the IA32 arch".
+Remember to set the environment variable UNAME_m to "i386".
+
+cat > mplayer.sh <<EOF
+#!/bin/sh
+
+export DISPLAY=<your display host goes here>:0
+while true;do
+ pos=100
+ for i in `jot 5`; do
+ mplayer -vc rv40win -geometry $pos:$pos /root/samples/Real_Media.rm < \
+ /dev/null > /dev/null 2>&1 &
+ pos=$((pos + 50))
+ done
+ for i in `jot 5`; do
+ wait
+ done
+done
+EOF
