   3 ## Getting the base ISO
   4
   5 This script assumes that you are starting with the special ISO from the
   6 following URL. It already contains video files that the script in this repo
   7 will not try to download. If you are not starting with that image, I suggest
   8 uncommenting the code in `install-extras.sh`.
   9
  10 <http://jenkins.trisquel.info/makeiso-etiona/iso/trisquel_9.0-fsf_i686.iso>
  11
  12 The corresponding source code ISO can be found here:
  13
  14 <http://jenkins.trisquel.info/makeiso-etiona/iso/trisquel_9.0fsf_sources.iso>
  15
  16 Feel free to test your download with the `trisquel_9.0-fsf_i686.iso.sha256`
  17 file in this repo:
  18
  19     sha2565sum -c trisquel_9.0-fsf_i686.iso.sha256
  20     sha2565sum -c trisquel_9.0fsf_sources.iso.sha256
  21
  22 If you want to use a 64 bit image instead, you can get one below, but you'll
  23 have to copy over the `fsf` directory from the image linked above to your
  24 member card. Otherwise, you'll be missing the video files that are included in
  25 the i686 ISO above. The browser window will also currently not launch after
  26 boot on the alternate 64 bit system.

  30 ## Making a bootable USB drive
  31
  32 This should work on an external USB drive, ideally one that is 12 GB or greater
  33 in size, if you want to intsall all of the media files onto it. Note that using
  34 a loop device will probably not work, partly due to the way syslinux behaves
  35 with loop devices. If you get that working, feel free to submit a patch to
  36 <sysadmin@gnu.org>. : )
  37
  38 You'll need to download and install old versions of syslinux:
  39
  40 * <https://oldarchive.trisquel.info/trisquel/pool/main/s/syslinux/syslinux-common_4.05+dfsg-6+deb8u1_all.deb>
  41 * <https://oldarchive.trisquel.info/trisquel/pool/main/s/syslinux/syslinux_4.05+dfsg-6+deb8u1_amd64.deb>
  42
  43 Check files, install them, and run the script:
  44
  45     sha256sum -c syslinux.deb.sha256
  46
  47     dpkg -i syslinux-common_4.05+dfsg-6+deb8u1_all.deb
  48     dpkg -i syslinux_4.05+dfsg-6+deb8u1_amd64.deb
  49
  50     sudo ./live-usb-loader.sh trisquel_9.0-fsf_i686.iso /dev/sdb
  51
  52 ## Installing extra media, including Trisquel 9 source code
  53
  54 This command also updates the Web page that shows up on boot.
  55
  56     sudo ./install-extras.sh trisquel_9.0fsf_sources.iso /dev/sdb
  57
  58 ## Notes about video files and free space
  59
  60 You may wish to transcode the downloaded videos to save space on the member
  61 card, in particular `lp2020_kahle.webm` and `lp2020_younghackers.webm`.
  62
  63     ffmpeg -i foo.webm -acodec libvorbis -b:a 64k -vcodec libvpx -vf scale=-1:720 -b:v 800k -preset medium foo_smaller.webm
  64
  65     # check to make sure that the video quality is okay
  66     mplayer foo_smaller.webm
  67
  68     mv foo_smaller.webm foo.webm
  69
  70 Then optionally update the checksum file for `/mnt/fsf/GNUAV/`:
  71
  72     cd /mnt/fsf/GNUAV/
  73     sha256sum ./ > ../checksums.sha256
  74     mv ../checksums.sha256 .
