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 | |
97a175de | 7 | will not try to download. |

15 | Feel free to test your download with the `trisquel_9.0-fsf_i686.iso.sha256` | |
16 | file in this repo: | |

27 | ## Making a bootable USB drive |
28 | ||
29 | This should work on an external USB drive, ideally one that is 12 GB or greater | |
96af59e8 AE |
30 | in size, if you want to intsall all of the media files onto it. Note that using |
31 | a loop device will probably not work, partly due to the way syslinux behaves | |
32 | with loop devices. If you get that working, feel free to submit a patch to | |
33 | <sysadmin@gnu.org>. : ) | |

34 | |
35 | You'll need to download and install old versions of syslinux: | |

40 | Check files, install them, and run the script: | |
41 | ||
42 | sha256sum -c syslinux.deb.sha256 | |
43 | ||
44 | dpkg -i syslinux-common_4.05+dfsg-6+deb8u1_all.deb | |
45 | dpkg -i syslinux_4.05+dfsg-6+deb8u1_amd64.deb | |
46 | ||
97a175de | 47 | sudo ./live-usb-loader.sh trisquel_11.0-fsf_amd64.iso /dev/sdb |

49 | ## Installing extra media, including Trisquel 9 source code | |
50 | ||

51 | This command also updates the Web page that shows up on boot. |
52 | ||
97a175de | 53 | sudo ./install-extras.sh trisquel_11.0_sources.tar /dev/sdb |

55 | ## Notes about video files and free space | |
56 | ||
57 | You may wish to transcode the downloaded videos to save space on the member | |
58 | card, in particular `lp2020_kahle.webm` and `lp2020_younghackers.webm`. | |
59 | ||
60 | ffmpeg -i foo.webm -acodec libvorbis -b:a 64k -vcodec libvpx -vf scale=-1:720 -b:v 800k -preset medium foo_smaller.webm | |
61 | ||
62 | # check to make sure that the video quality is okay | |
63 | mplayer foo_smaller.webm | |
64 | ||
65 | mv foo_smaller.webm foo.webm | |
66 | ||
67 | Then optionally update the checksum file for `/mnt/fsf/GNUAV/`: | |
68 | ||
69 | cd /mnt/fsf/GNUAV/ | |
70 | sha256sum ./ > ../checksums.sha256 | |
71 | mv ../checksums.sha256 . | |
