Installing KnoppMyth

There are two ways to install KnoppMyth. The easiest is to use normal formatting and over-write the internal disk. The other method of installing to GPT formatted disks is still being developed and will be updated at a later time.

KnoppMyth R5F27

Over-write the internal disk

This method is pretty simple, make a USB flash drive with atv-bootloader, boot the AppleTV, backup the AppleTV, then boot the KnoppMyth CD installer, and install KnoppMyth to the internal PATA disk. Then create a custom "boot_linux.sh" that atv-bootloader uses to boot the installed KnoppMyth.

Audio and IR support requires a kernel patch/rebuild as 2.6.18 is too old to accept usbhid kernel module options. In addition, the nvidia driver will need to be updated to a 169.xx version.

Remove MythBackEnd

Stop and remove mythtv-backend

/etc/init.d/mythtv-backend stop
update-rc.d -f mythtv-backend remove

Stop and remove mysql server

/etc/init.d/mysql stop
update-rc.d -f mysql remove
apt-get remove mysql-server xmltv
rm -rf /var/lib/mysql/*
rmdir /var/lib/mysql
rm -rf /var/log/mysql/*
rmdir /var/log/mysql

Stop and remove apache

/etc/init.d/apache2 stop
update-rc.d -f apache2 remove

Now change the MythTV settings to point at your existing backend database. Edit the file

nano /etc/mythtv/mysql.txt
