Obtain a FAT formatted mini SD card. I don't think it matters if it's fat16 or fat32, but 2GB or less is best. Obtain IZ2S205beta-enhanced-020410.zip from here: http://russelldavis.org/2010/10/21/proper-release-of-iz2s-enhanced/ Unzip the IZ2S zip file onto to the root of the mini SD card. Copy gmu-gmenu2x-jffs.tgz to the root of the mini SD card. Boot IZ2S: Skip the wifi setup. If first time running IZ2S wait for it to generate keys. At command prompt type: cd /mnt/ffs mkdir /mnt/sd0/backup cp -R * /mnt/sd0/backup/ sync sync rm *.arl rm *.xml rm -rf wpa_supplicant rm *.jpg rm Z* sync sync ls You should have only properties.txt and start.sh left. /mnt/sd0/bin/busybox tar -xzvf /mnt/sd0/gmu-gmenu2x-jffs.tgz sync sync df -h poweroff Wait for screen to go black. Remove IZ2S sd card. Press the green button. Answer questions until you get a command prompt. Then type: gmenu For some reason i didn't get connected with wifi the first time, but it did connect after a reboot. I'm keeping an eye on that.
