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

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