ATTENTION!!!! This page is not up to date!

If you are installing an R5 version, you should follow the instructions listed at http://www.mysettopbox.tv/doc.html FIRST! A copy of these instructions can also be found here on the wiki at <em class="highlight marker searchword-0">KnoppMyth</em>R5PreviewInstall?. Also be sure to look for the current "Hints" (e.g. "highlight marker searchword-0?") thread in the !<em class="highlight marker searchword-0">KnoppMyth</em> Forums. These generally serve as the release errata documentation.

<em class="highlight marker searchword-1">INSTALLATION</em>

Knoppmyth R5.5 Install Video hosted on youtube shows just how easy it is to install R5.5!

NOTE: North American users need to register at SchedulesDirect. Be sure to remember your login/password for use during mythtv-setup. DO THIS FIRST - otherwise, if you don't have this information available when it's needed it will throw off the rest of the setup instructions and your tuner won't know the correct channel/frequency information, meaning that when you try to 'watch TV' all you'll see is "snow" or noise if anything.

1. Set the system to boot from CD in your computer's BIOS.

2. Restart your system with the <em class="highlight marker searchword-0">Knoppmyth</em> CD in the drive.

3. At the splashscreen, press Enter at the boot: prompt if you do not have your computer connected to a TV via TV-out.

If you do have your computer connected to a TV via TV-out, type tv at the boot: prompt and press Enter. This will set your video adapter to a resolution of 800x600. You will still need to edit /etc/X11/XF86Config-4 to change the refresh rate or you can destroy your TV.

If you are using a 640x480 monitor type: <em class="highlight marker searchword-0">knoppmyth</em> screen=640x480 at the prompt. If your screen freaks out type Ctr-Alt-F1 to enter terminal mode.

If you are using an LCD monitor and the screen appears scrambled use fb800x600 at the boot: prompt (you can put additional commands after this as mentioned in the F2 help)

5. Once the CD boots, you see six options:

Options 5 and 6 are self-explanatory. Here are descriptions of the first four options.

Frontend

This allows you to use the CD as a frontend if you have a MythTV backend previously set up.

Using the CD as a frontend is dependent on the backend having already been configured with MySQL listening on the network. If you are running <em class="highlight marker searchword-0">Knoppmyth</em> as your backend server, you can configure it as follows:

1. Edit /etc/mysql/my.cnf and comment out 'skip-networking'.

Before: skip-networking
After: # skip-networking

2. Note that the backend will only accept the mythtv user with a password of mythtv.

3. Restart MySQL as root by opening an Xterm window and typing:

su
/etc/init.d/mysql restart
exit

4. As the mythtv user, reconfigure mythtv. In the Xterm window from step 3 above, type:

mythtv-setup

On the first screen of MythTV setup, change both instances of the loopback IP number (127.0.0.1) to the actual IP number of the backend server. Then press ESC to exit mythtv-setup, and restart mythbackend:

su
/etc/init.d/mythtv-backend restart
exit

Now that the backend is set up correctly, boot the frontend system with the <em class="highlight marker searchword-0">Knoppmyth</em> CD. Select the frontend option, and enter your time zone information.

In the Configure <em class="highlight marker searchword-0">Knoppmyth</em> Database dialog that follows, select No to change the current configuration. You should only need to change DBHostName from localhost to the IP number of your backend server: all other settings should remain at their default settings.

In the next dialog, choose either DHCP Broadcast for an assigned IP number from your router, or enter your own IP settings.

MythTV should then connect to the backend server.

Autoinstall

This will automatically perform a complete <em class="highlight marker searchword-1">installation</em> of <em class="highlight marker searchword-0">KnoppMyth</em>.

1. Provide the requested information in the various dialogs that appear after selecting autoinstall. Note that the time zone and current time may not appear to be set at this point: you will have another opportunity to set it after the initial <em class="highlight marker searchword-1">installation</em> is complete. You will also be warned that <em class="highlight marker searchword-1">installation</em> will erase all the contents of the hard drive.

If you get the error: /usr/local/bin/<em class="highlight marker searchword-0">KnoppMyth</em>-auto: line 608: / 1000000: syntax error: operand expected (error token is "/ 10000000") this is probably due to your harddisk not supporting DMA, you are using a serial-ATA (SATA) drive, or possibly you have your hard drive in ide channel 2 and CD in channel 1. In the Serial drive case, your disk is not /dev/hda as <em class="highlight marker searchword-0">KnoppMyth</em> expects it to be You may need to start again and use <em class="highlight marker searchword-0">knoppmyth</em> ide=nodma from the boot: menu and in the case of an SATA drive ide=reverse. If both fail, check whether your BIOS comes up with a SATA legacy or SATA compatibility mode or similiar to turn your serial ATA into a PATA drive. If nothing helps, get yourself a parallel ATA drive and connect it as master to your IDE controller 0.

This error message and another scenario where the "format drive" screen <em class="highlight marker searchword-2">freeze</em>s at <em class="highlight marker searchword-3">14</em>% can be explained by the fact the the primary hard drive is not set as the Master drive on the primary IDE channel. Rearrange the cables and possibly change the drive jumpers to fix this (insure the jumper is not set to Cable Select but to Master).

When you are asked for username - DO NOT USE MYTHTV - use your own name! The install already uses mythtv and using it again will cause problems.

2. After the initial <em class="highlight marker searchword-1">installation</em> is complete, the system will reboot into X, and <em class="highlight marker searchword-0">KnoppMyth</em> will open an Xterm window. When prompted, type the root password.

If the boot messages indicate that aumix could not load, and you have a AC'97 based sound system, read the related item in the Tips section below before you go any further.

3. In the prompts that appear, choose i586 if you have a Pentium-class processor, or i686 if you have a Pentium Pro or higher (or Athlon or higher). You can also choose to install remote control support (LIRC), and if you have an nVidia graphics card, XvMC support (but NOTE the additional <em class="highlight marker searchword-1">installation</em> steps required below in steps 5-7). You will also re-select a time zone and date/time.

4. Configuration will proceed, and the front end will attempt to start for the first time.

5. If you have an nVidia graphics card, when the front end attempts to start (the Xterm window will disappear and the <em class="highlight marker searchword-0">KnoppMyth</em> desktop will remain on the screen), you will have to install the nVidia graphic drivers. To do this, press <CTRL><ALT><F1> to exit X.

6. To install the nVidia drivers. Log in as root, type cd /usr/local/bin then type ls *nvidia* and then type install-nvidia-xxxx-debian.sh where xxxx is the driver version included in your <em class="highlight marker searchword-0">KnoppMyth</em> distribution.

7. After the drivers have been installed, then type either:

install-i586-x (for XvMC support on Pentium-class machines)
install-i686-x (for XvMC support on Pentium Pro/Athlon machines)
install-i586-lx (for XvMC and LIRC support on Pentium-class machines)
install-i686-lx (for XvMC and LIRC support on Pentium Pro/Athlon machines)

NOTE:

As described in: http://mysettopbox.tv/phpBB2/viewtopic.php?t=1229 XvMC only improves video display performance for systems that have an nVidia card, a PVR or HDTV card that performs hardware based mpeg decoding, and a slow CPU that otherwise couldn't keep up. You don't want to install it unless absolutely necessary since (at least in the past according to several mysettopbox.tv forum posters) it has led to frozen screens under a wide variety of provocations.

If you have an nForce chipset or any nVidia graphics card, and want to use its TV out capability, you may want to edit /etc/X11/XF86Config-4 and add:

Option "ConnectedMonitor" "TV"

to do so, type

"nano /etc/X11/XF86Config-4" #press enter

Put the option line into the section with monitor, and REMEMBER to ALT-X and ALT-O to save your changes!!

More options are available at: ftp://download.nvidia.com/XFree86/Linux-x86/1.0-4363/README.txt . There is also a sample XF86Config-4 file for nVidia and TV Out in the /etc/X11/ directory.

Note to PAL users: This sample file is set up for NTSC. You need to change "NTSC-M" to "PAL-B" (for Germany, see other options at the above link). If you are connecting to a SCART adaptor, you also need to change "SVIDEO" to "COMPOSITE".

If you have only a TV and no monitor, the first time X starts the screen will be unreadable. Press <CTRL><ALT><F1>, log in as root, execute "<em class="highlight marker searchword-0">KnoppMyth</em>-run -~" and answer all the questions. When it prompts for a reboot, Press <ALT><F2>, log in as root, create the XF86Config-4 file, install the nVidia drivers and X should be restarted automatically. Don't enter the root passwd. Instead <CTRL><ALT><F1> and then answer Y to a reboot. This should then continue as normal.

8. Finally, follow the directions for setting up MythTv that can be found in the MythTv howto (starting at about page 42 of the pdf version or section 9 "Configuring MythTV" of the html version). See for example: http://www.mythtv.org/docs/mythtv-HOWTO.html

Because some of the functionality of setup is built into <em class="highlight marker searchword-0">Knoppmyth</em>, you need to know the following:

a) After you have filled in the Backend configuration (the first set of screens brought up by the <em class="highlight marker searchword-0">KnoppMyth</em> installer, don't edit the channel information.

b) When finished with the other setup screens, hit escape until you leave the backend configuration screens. At this time the installer will automatically run the mythfilldatabase code.

c) When mythfilldatabase has completed, the frontend screens will be launched.

d) If the grabber selected is configured in a terminal window, rather than within myth_setup, it is possible to switch to the terminal by pressing alt+tab. Once the configuration is complete the window can be hidden by pressing the button at the top left with a small dot on it. When myth_setup is exited then the window can be returned by double clicking the item on the desktop. (--peteredworthy--)

e)For the uk use UK (Alternative) as the main uk grabber no-longer works (--peteredworthy--)

Nvidia driver install with Myth version R5E50

I got this from a fourm post after many hours of not being able to get the Nvidia driver loaded on R5E50 INSTALL Kernal source (Need to do this before installing video driver)

wget ftp://<em class="highlight marker searchword-0">knoppmyth</em>.net/R5/linux-source-2.6.18-chw-13_2.6.18-chw-13-10.00.Custom_all.deb

dpkg -i linux-source-2.6.18-chw-13_2.6.18-chw-13-10.00.Custom_all.deb

cd /usr/src

tar xjvf linux-source<tab>

PREP FOR DRIVER INSTALL

cd /usr/src/linux-headers-2.6.18-chw-13

cp -r . ../linux-source-2.6.18-chw-13

This merges the kernel-headers with the kernel-source, since the source by itself doesn't have the configuration files that were used. Next, on my system at least, I had to at least partially make the kernel again, because certain kernel module scripts weren't in a usable state until you did that. So I did the following:

cd /usr/src/linux-source-2.6.18-chw-13

make

wait about 20 seconds and then hit ctrl-c?

Now we're ready to install the new driver. The easiest way to do this is the rename the startx script and reboot so that X is not even trying to boot up.

mv /usr/bin/startx /usr/bin/startx.save

reboot

For some reason the NVidia install script isn't yanking out the original nvidia kernel module, so I manually pulled it out with this command:

rmmod nvidia

lsmod | grep nvidia

The second command will let you verify that you no longer have the module loaded. Now we're actually ready to run the binary web hosting package from NVidia. It doesn't quite detect everything correctly, so issue the command as such:

sh NVIDIA-Linux-x86-1.0-9746-pkg1.run \

--kernel-source-path=/usr/src/linux-source-2.6.18-chw-13

You will most likely get a message during the <em class="highlight marker searchword-1">installation</em> process that it had to make assumptions about the paths for X.org. The assumptions that it made are fine.

Once the installer is finished you should be able to safely start X back up, but don't forget to rename your startx executable.

mv /usr/bin/startx.save /usr/bin/startx

Auto Upgrade

This will automatically upgrade <em class="highlight marker searchword-0">KnoppMyth</em> from an earlier version (R3 or R4).

First, as root, run mythbackup. This backs up /etc/mythtv and /home/mythtv as well as the mythconverg database to /myth/backup/. When you do an Auto Upgrade, hda1 is wiped clean. The /myth partition is not erased, so if you have customized your /etc/X11/XF86Config-4 file, you can copy it there. After the Auto Upgrade is done and your system reboots, mythrestore is run, and your database and /home/mythtv files are restored.

When performing an Auto Upgrade, the same options as Auto Install are offered... consult that section for information on how to choose the appropriate install option and info on how to properly configure TV Out.

Manual Install

Manual install is recommended only for advanced users.

NOTE:

NOTE: For <em class="highlight marker searchword-0">Knoppmyth</em> R5B7, the /cache partition is no longer required. I recommend making a larger / partition (5-10 Gigabytes) and giving the rest to swap and /myth.

NOTE:

After the system reboots it will start X and <em class="highlight marker searchword-0">KnoppMyth</em> will open an Xterm and ask for the root password.

However DO NOT install it until after configuration has started and the frontend starts for the first time. Then exit the frontend by pressing <CTRL><ALT><F1>. Login in as root. install-i586-x will install the i586 package with XvMC. If you have a 686 class processor substitute 5 with 6. install-i586-lx will install the i586 package with native LIRC and XvMC. If you have a 686 class processor substitute 5 with 6. Typing install-nvidia.sh will then install the nVidia drivers.

NOTE:

Option "ConnectedMonitor" "TV"
# This is only if attaching to a TV

For more options, please see: ftp://download.nvidia.com/XFree86/Linux-x86/1.0-4363/README.txt

A sample XF86Config-4 for nVidia w/ tv out is in /etc/X11/

Filesystem layout

<em class="highlight marker searchword-0">KnoppMyth</em> uses the following filesystem layout:
/cache/cache (for the ring buffer)
/myth

Added software packages

Tips and Hints

These extra notes only pertain to R5 alphas.

Extra notes:

While tuner cards are detected, the modules may not be loaded. This is true for ivtv based cards. To work around, when the system first boots to X: <CTRL><ALT><F1> Log in as root.
Code:
modprobe ivtv
echo ivtv >> /etc/modules
reboot

LIRC is being problematic... If you have a PVR x50 make /etc/modprobe.d/lirc that looks like(may work for some):
alias char-major-61 lirc_i2c
install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install lirc_i2c

Add /usr/local/sbin/lircd to /etc/init.d/bootmisc.sh
Then run update-modules (as root)

If this doesn't work for you, vi /etc/init.d/bootmisc.sh and add:
modprobe lirc_i2c
/usr/local/sbin/lircd

Watch TV doesn't work after rebooting (using firewire)

For some reason, after a clean uneventful install and you are able to watch live tv, you are then unable to watch live tv after rebooting. I get the dreaded 15 seconds and no signal error. I found to fix this:

1. Exit or stop mythfrontend.

2. Stop mythbackend with:

/etc/init.d/myth-backend stop

3. Asuming your CableBox is on Node 1:

plugctl -n 1 opcr[0].channel=63
plugctl -n 1 opcr[0].bcast_connection=1

4. Now start mythbackend with:

/etc/init.d/myth-backend start

5. Now you may run 'mythfrontend' and test to make sure you can watch live tv.

You may want to modify /etc/init.d/myth-backend essay help script and add this code research paper help so it is automatically done by cv writer when starting mythbackend.
