This HOWTO is a step-by-step guide to getting the HP Z556 Media Center setup for use with Ubuntu 7.04 & MythTV.

HP Z556

Hardware Overview

This HOWTO aims to collect the multitude of tips regarding optimizing performance of your system for use with MythTV.

Installing the OS

Download / Burn / Boot

This walk through is based on Ubuntu 7.04 "Fiesty Fawn"

Download from here: http://www.ubuntu.com/news/Ubuntu704Beta

Installation Tips

For you file system choose either the XFS file system

After you boot into your desktop open a console and type

   restricted-manager

and check the nvidia display drivers let it go through its process and then restart


Getting the hardware to work

PCI Bus output

This is a lspci of the system

   01:00.0 VGA compatible controller: nVidia Corporation NV43 [GeForce 6600] (rev a2)
   02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 19)
   03:01.0 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394 Host Controller (rev 80)
   03:03.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
   03:03.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder [MPEG Port] (rev 05)
   03:04.0 PCI bridge: Hint Corp HB6 Universal PCI-PCI bridge (non-transparent mode) (rev 11)
   03:05.0 Ethernet controller: Atheros Communications, Inc. AR5006X 802.11abg NIC (rev 01)
   04:08.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)
   04:09.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)

All the hardware works with the default install of Ubuntu 7.04 except for the HD Tuner which needs a little tweak to get it to work. After hours of reading I find out HP modified this card to fit in the case and for some reason it doesn't auto detect the card and tuner.


PVR-500 (IVTV Drivers)

I am going to go out on a limb and do a walk through with the HG repo's of LinuxTV just for the fact that IVTV is integrated directly into this branch and plays well with all the other devices. IVTV integrated separately tends to break DVB cards supported by LinuxTV. This does require some compiling but it was very easy to do and aloud me to install a 2nd & 3rd USB HDTV tuner the (HVR-950). That way if you decide to add any USB v4l devices chances are they will work.

The Old way: https://help.ubuntu.com/community/Install_IVTV_Feisty


My way from HG repos

   sudo su
   apt-get install mercurial linux-headers-$(uname -r) linux-source build-essential

IVTV Firmware

   wget http://dl.ivtvdriver.org/ivtv/firmware/firmware.tar.gz
   tar xvzf firmware.tar.gz

Optional Extract Firmware for v4 V4L devices like (HVR-950)

   cd /lib/firmware
   wget http://konstantin.filtschew.de/v4l-firmware/firmware_v4.tgz
   tar xvzf firmware_v4.tgz

Compile the latest V4L-dvb tree with IVTV drivers

   cd /usr/src/
   hg clone http://mcentral.de/hg/~mrec/v4l-dvb-experimental/
   cd v4l-dvb-experimental
   make
   make install
   

Reboot



Testing NTSC Tuner Cards

in a console type

   dmesg | grep ivtv | grep 'video' | grep 'MPEG'

which should output something similar to:

   [   23.520549] ivtv0: Registered device video1 for encoder MPEG (4 MB)
   [   30.070392] ivtv1: Registered device video2 for encoder MPEG (4 MB)

this means your 1st NTSC tuner card is set at /dev/video1 and your 2nd at /dev/video2

  • this will be needed for mythtv down the road so write it down.

ATI HDTV Wonder (CX23880/1/2/3 Chipset)

we need to extract the nxt2004 firmware

in a console type:

   sudo apt-get install linux-doc-2.6.20
   
   cd /usr/share/doc/linux-doc-2.6.20/Documentation/dvb
   
   sudo gzip -d get_dvb_firmware.gz
   
   sudo chmod +x get_dvb_firmware
   
   sudo ./get_dvb_firmware nxt2004
   
   sudo cp dvb-fe-nxt2004.fw /lib/firmware/
   sudo gedit /etc/modprobe.d/options

Add the following to the file:

   options cx88xx card=34 tuner=68

After a reboot this card should be working and "dmesg | grep cx" should output something like this:

   [   16.852541] ivtv0: Autodetected Hauppauge card (cx23416 based)
   [   17.048053] cx2388x cx88-mpeg Driver Manager version 0.0.6 loaded

Testing ASTC Tuner Card (ATI HDTV Wonder)

in a console type

   ls /dev/dvb/

you should see something similar to:

   adapter0

if you see this all is well for now and we can test all the card functionality later once myth is setup


Wireless Card

   03:05.0 Ethernet controller: Atheros Communications, Inc. AR5006X 802.11abg NIC (rev 01)

This uses the Madwifi Drivers which are installed by default with Ubuntu 7.04

If you need to compile them see : http://www.madwifi.org

this is an output of what modules are loaded: lsmod | grep ath

   ath_rate_sample        14080  1 
   ath_pci                97312  0 
   wlan                  204484  4 wlan_scan_sta,ath_rate_sample,ath_pci
   ath_hal               192592  3 ath_rate_sample,ath_pci

Memory card reader

Works with stock ubuntu kernel

Remote Control

Uses the MCE2 USB modules wonderful how-to here: http://www.mythtv.org/wiki/index.php/Ubuntu_lirc_install

this is an output of what modules are loaded: lsmod | grep mce

   lirc_mceusb2           14084  0 
   lirc_dev               15988  2 lirc_i2c,lirc_mceusb2

VFD LCD Front Panel

Front Panel Buttons

The buttons on the front can be mapped with xmodmap

   sudo cat /proc/bus/input/devices

To find what event interface your VFD shows up on. This is an example of where mine is:

   I: Bus=0003 Vendor=1460 Product=0024 Version=0100
   N: Name="HP HP VFD Front Panel Board"
   P: Phys=usb-0000:00:1d.7-5.2/input0
   S: Sysfs=/class/input/input3
   H: Handlers=kbd event3 
   B: EV=3
   B: KEY=8000 68 4000 800000 0 0 0
