├── android-system │   ├── initrd.img │   ├── install.img │   ├── kernel │   ├── ramdisk.img │   └── system.sfs ├── android-x86.xpm.gz ├── cmdline ├── grub4dos ├── kernel -> grub4dos ├── lost+found ├── menu.lst └── ramdisk . 2 directories, 11 files

steps to change files in system.sfs (system.img) * Ubuntu 10.4 box * change to shell, press strg+alt+F1 * sudo -i * aptitude and install squashfs-tools * modprobe squashfs * cd /home/administrator * copy system.sfs (squash file system) to harddisk, in /home/administrator * mkdir systemsfs * mount ./system.sfs ./systemsfs -t squashfs -o loop * copy ./systemsfs/system.img /home/administrator/ * mkdir systemimg * mount ./system.img ./systemimg -t ext2 -o loop

now cd to systemimg directory and make the changes

eg. change *.kl files for sound F7 (scanncode=65) = mute; F8 (scanncode=66) = volume_down; F9 (scanncode=67) = volume_up * cd usr/keylayout * vi *.kl * change lines key 113  VOLUME_MUTE key 114  VOLUME_DOWN key 115  VOLUME_UP

key 65  VOLUME_MUTE key 66  VOLUME_DOWN key 67  VOLUME_UP
