# Booting

*   get a copy of boot.efi

$ md5sum boot.efi
    280323d8700e4cfef15116f7e50590e3  boot.efi

# Installation

Needed ncurses for "make menuconfig", not strictly necessary

## Prepare the image

dd if=/dev/zero of=usb-boot.img bs=1M count=63
    sudo losetup -f usb-boot.img
    parted /dev/loop0
    (parted) mklabel gpt
    (parted) mkpart EFI 0 4
    (parted) set 1 boot on
    
    (parted) mkpart Recovery 4 8
    (parted) mkpart OSBoot 8 12
    (parted) mkpart Media

Oops. That loopback partitioning patch never made it into the kernel. So can't do much with this image now...

parted print /dev/sdb
    Disk /dev/sdb: 64.5MB
    Sector size (logical/physical): 512B/512B

*   create gpt disk label 
*   create fat32 EFI boot 
*   create recovery, osboot and media

# Log

#### 2007-06-27

*   apple TV seems to be trying to boot from usb stick 
*   check USB stick 
*   opened Apple TV 
*   need 44-pin to 40-pin IDE adapter

## Backup

#### 2007-07-13

*   connect appletv to 
*   backup disk

$ dd if=/dev/hdc | gzip -1 | nc -w 5 192.168.1.5 31066

And on the backup machine (192.168.1.5):

$ nc -l -p 31066 > appletv-backup.img.gz
    $ ls -l appletv-backup.img.gz
    -rw-r--r--  1 backup users 4018217943 2007-07-14 06:30 appletv-backup.img.gz

## Installation

#### 2007-07-14

*   install mb\_boot\_tv 
*   repartition disk 
*   install Linux

On the machine used for partitioning and installing Linux, the appletv HDD is /dev/sdb

# mount /dev/sdb3 -t hfsplus /media/OSBoot
    # mount /dev/sdb2 -t hfsplus /media/Recovery
    # cp ~/appletv/mb_boot_tv /media/OSBoot/
    # cp ~/appletv/mb_boot_tv /media/Recovery/
    # chmod 755 /media/{OSBoot,Recovery}/mb_boot_tv
    # umount /media/OSBoot
    # umount /media/Recovery

### Repartition

Repartition the disk. Create boot, root and swap

# parted /dev/sdb
    (parted) print

## Kernel Build

#### 2007-10-3

Cross-compile updated kernel

*   <http://osdir.com/ml/linux.gcc/2004-02/msg00008.html>

Cross-Compile an [AppleTV][43] kernel on an AMD64 and install.

Extract

$ wget http://www.eu.kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.2.tar.bz2
    $ #[[http://forum.awkwardtv.org/viewtopic.php?f=23&t=167&hilit=&start=70|rca-patch]]
    $ wget http://hester.no-ip.org/appletv-rca-sound.patch.gz
    $ wget -O appletv-ir.patch http://cbg.dyndns.org/store/apple-remote-quirk-hiddev.patch
    $ svn co http://mactel-linux.svn.sourceforge.net/svnroot/mactel-linux/trunk/mach_linux_boot/kernel/
    $ tar -xjvf linux-2.6.22.2

Patch

$ cd linux-2.6.22.2
    $ cp ../kernel/config-2.6.22.2-appletv .config
    $ patch -p1 < ../kernel/2.6.22.2-appletv.patch
    $ cat ../appletv-rca-sound.patch.gz | gunzip - | patch -p1
    $ patch -p1 < ../appletv-rtc.patch
    $ patch -p1 < ../appletv-ir.patch

What the patches do:

*   appletv-rca-sound - changes the detection of the RCA sound chip 
*   appletv-rtc - disables RTC, preventing oopses 
*   appletv-ir - forces [AppleTV][43] IR to be detected as an HID device

Build

$ make ARCH=i386 CROSS_COMPILE= menuconfig
    $ make-kpkg --arch i386 --cross_compile - clean
    $ CONCURRENCY_LEVEL=6; fakeroot make-kpkg --arch i386 --cross_compile - kernel_image kernel_headers

Switch to [AppleTV][43]

Install kernel

# dpkg --force-architecture -i linux-image-2.6.22.2-appletv_2.6.22.2-appletv-10.00.Custom_amd64.deb
    # dpkg --force-architecture -i linux-headers-2.6.22.2-appletv_2.6.22.2-appletv-10.00.Custom_amd64.deb

Update nVidia drivers

*   <http://wiki.debian.org/NvidiaGraphicsDrivers>

Add non-free and contrib sources to host /etc/apt/sources.list

# vim /etc/apt/sources.list
    deb http://ftp.uk.debian.org/debian/ etch main non-free contrib
    deb-src http://ftp.uk.debian.org/debian/ etch main non-free contrib
    EOF
    # apt-get update

Get nVidia kernel source

# apt-get install nvidia-kernel-source
    # cd /usr/src
    # tar -xzvf nvidia-kernel-source.tar.gz
    # cd linux-2.6.22.2
    # make-kpkg modules_image

Install new nVidia binary kernel

# dpkg -i nvidia-kernel-2.6.22.2-appletv-01_1.0.8776-4+2.6.22.2-appletv-01_i386.deb

## Window Manager

.profile

if [ -z "$DISPLAY" ] && [ $(tty) == /dev/tty1 ]; then
    while [ 1 == 1 ]
            do
                    startx
                    sleep 10
            done
    fi

Remove fluxbox, use ratpoison instead

# apt-get install ratpoison
    # su mythtv
    $ cat > ~/.ratpoisonrc
    escape C-r   #Make escape (default C-t) not clash with mythTV key bindings
    addhook switchwin banish #Banish the mouse cursor out of the way.
    EOF
    $ vim ~/.xinitrc
    (replace fluxbox with ratpoison)
    $ exit
    # apt-get remove fluxbox

"Ctrl-R ?" shows ratpoison options

#### 2007-12-04

Fix .xinitrc so it restarts mythfrontend following a crash

$ cat > .xinitrc
    exec xset s off &
    exec xsetroot -solid black &
    exec ratpoison & ratpid=$!
    exec $HOME/launch_myth.sh &
    wait $ratpid
    EOF

$ cat > /home/mythtv/launch_myth.sh
    #!/bin/sh
    for i in {1..25} ; do
            mythfrontend 2>> $HOME/MYTHERRORS
            EXIT=$?
            if (( $EXIT == 0 )) ;
                    then exit $EXIT
            fi
    done
    EOF
    $ chmod u+x launch_myth.sh

This now restarts mythfrontend up to 25 times. If X crashes then .profile restarts it.

## Samba

#### 2007-10-10

Fix Samba streaming

$ echo "cache=1024" >> ~/.mplayer/config

Forces mplayer to precache 1MB of a media file

## Upgrade to Lenny

#### 2008-02-24

dist-upgraded to Lenny in order to test Elisa and other media systems

## Kernel Update

Update to 2.6.23.11

*   [http://wiki.awkwardtv.org/wiki/Apple\_TV\_Linux_Kernel][46] 
*   No nvidia-glx in Lenny, so download from nvidia:

# wget http://us.download.nvidia.com/XFree86/Linux-x86/100.14.23/NVIDIA-Linux-x86-100.14.23-pkg1.run
    # chmod +x NVIDIA-Linux-x86-100.14.23-pkg1.run
    # ./NVIDIA-Linux-x86-100.14.23-pkg1.run --no-x-check --no-kernel-module

Run the NVIDIA installer, but do not replace the kernel module installed from the non-free repos

## Frontrow

OK, issues with Lenny graphics drivers. So no go. Perhaps I could downgrade again...

Either way, MythTV UI just doesn't cut it, so I'm dumping it and moving to Frontrow plus Plugins...

* * *

# XBMC on Linux on [AppleTV][43]

*   [Howto][47] 
*   Using Karmic instead of Hardy (no Boxee for Hardy)

        # vim /root/xorg.conf.new
         Section "Device"
             Identifier     "Device0"
             Driver         "nvidia"
             VendorName     "NVIDIA Corporation"

    svn checkout http://crystalhd-for-osx.googlecode.com/svn/tags/crystalhd-for-osx-3.6.0
    cd crystalhd-for-osx-3.6.0/crystalhd/linux_lib/libcrystalhd
    make
    sudo make install
    cd ../../driver/linux
    autoconf
    ./configure
    make
    sudo make install
    sudo modprobe crystalhd
    cd

## XBMC

*   Download nightly from [http://sshcs.com/xbmc/Binaries/Builds/XBMC\_Linux\_34311.rar][48] 
*   Remove old XBMC and install dependencies

$ sudo apt-get remove xbmc xbmc-bin xbmc-data
    $ sudo apt-get install libavcodec52 libssh-3 libass4

*   No libass4 so upgrade to later distro?

*   Install svn version from ppa

$ sudo apt-get install xbmc=2:10.00~svn33778-karmic1

### Fix Green Tint

*   Set video renderer to GLSL

### Restart on crash

*   cat .xinitrc

#!/bin/sh
    while (! xbmc --standalone )
    do
    	sleep 2
    done

## Autostart on Boot

*   <http://forum.xbmc.org/showthread.php?t=38473> 
        $ sudo apt-get install mingetty
        $ sudo vi /etc/init/tty1.conf

*   cat /etc/init/tty1.conf 
        exec /sbin/mingetty --autologin appletv tty1

*   cat ~/.bash_login 
        if [[ x`pidof X` = "x" ]]
        then 
                startx
        fi

## Reduce stream timeouts

Set system-wide TCP connect retries

# echo "net.ipv4.tcp_syn_retries=2" >> /etc/sysctl.d/60-xbmc-tweaks.conf

## Custom Keymap

*   Edit ~/.xbmc/userdata/keymaps/joystick.AppleRemote.xml 
*   Set fullscreen video plus and minus to BigStepBack or SkipPrevious

## AAC mono bug

*   Mono AAC does not play with 5.1 speaker setting 
*   <http://forum.xbmc.org/showthread.php?t=88953&highlight=aac+mono>

### Solution

*   set speaker setup to 2.1 in XBMC 
*   multichannel lossy encodings would play as 2.1 only 
*   passthrough is unaffected

## Slow Slideshow bug

*   Slideshows play incredibly slowly 
*   <http://forum.xbmc.org/showthread.php?t=44770>

## Upgrade to Precise and XBMC Eden

#### 2012-04-29

### Lucid

*   Update to Ubuntu LTS - 10.04 (Lucid) 
*   Generate Ubuntu Lucid sources list from <http://repogen.simplylinux.ch/generate.php> 
*   Update to Lucid 
        sudo aptitude update && sudo aptitude dist-upgrade

*   Oops. Killed it. Won't boot after installation of 10.04.

Possibly just have to update the patchstick.

### Lucid Patchstick

*   [http://wiki.xbmc.org/index.php?title=HOW-TO\_install\_a\_Miminal\_Ubuntu\_and\_XBMC\_with\_sound\_over\_HDMI\_on\_the_AppleTV][47] 
*   Grab 10.04 netboot 
        cd appletv/lucid
        wget 'http://uk.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-i386/current/images/netboot/netboot.tar.gz'
        tar xfz netboot.tar.gz

*   Update patchstick 
        sudo su
        # fsck.hfsplus /dev/sdb1
        # fsck.hfsplus /dev/sdb2
        # mount /dev/sdb2 /mnt/patchstick/PATCHSTICK
        # cp ubuntu-installer/i386/linux /mnt/patchstick/PATCHSTICK/
        # cp ubuntu-installer/i386/initrd.gz /mnt/patchstick/PATCHSTICK/

Dammit, actually it was fine all along! SSH'd in without problems.

*   Upgrade 
        sudo aptitude update && sudo aptitude upgrade

*   Failure to configure python-minimal 
    *   Launchpad [#990740][52] 
        E: Could not perform immediate configuration on 'python-minimal'.Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)
        
        
    
    *   Workaround (via stefanor) is to upgrade apt first, then do-release-upgrade. 
    *   Too late for do-release-upgrade, so install python-minimal then the rest.

*   Other packages 
        sudo aptitude install xbmc
        sudo aptitude install nvidia-current

*   Rebooted, screwed up the kernel images 
*   Installed nvidia, failed to initialize GLX 
        Failed to initialize the GLX module; please check in your X log file that the GLX module has been loaded in your X Server, and that the module is the NVIDIA GLX module. If you continue to encounter problems, Please try reinstalling the NVIDIA driver.
        
        
    
    *   run nvidia-xconfig to fix it 
        sudo nvidia-xconfig

# OpenELEC

*   Dumped XBMC on Ubuntu after because of freezing on home screen issue

## Install

*   Created OpenELEC patchstick 
*   Wouldn't boot (possibly the backup GPT table) so zeroed the USB stick and recreated it 
*   Booted successfully

## Configuration

*   OpenELEC wiped the whole of the old installation 
*   Reinstate Xeebo skin 
*   Re-add media sources and update libraries

### Users and SSH

*   add gnome user, disable root login, disable password login
