1. File linux24 and a few others are NOT installed when doing a hard disk install. Remedy: Create a boot floppy and copy the files from there to the hard disk partition.
2. /etc/fstab had to be altered, a mountpoint /home had to be specified for /dev/hdb9 and an empty directory /home created. Still DSL refused to mount /dev/hda9 when issuing the command "mount". Remedy: Disable the allocation of /home/dsl as value for the variable $HOME in /etc/init.d/dsl-config and add the command: "mount -a" in /opt/bootlocal.sh
3. Re-create users waldis and dsl with appropriate groups.
4. Disable the "back-up to and re-load from harddrive" routine /etc/init.d/dsl-restore.sh by inserting as first command an "exit 0"
5. Set the run-level in /etc/inittab to 3.
6. Change on the Mandriva system the file /etc/lilo.conf and run lilo. The DSL entry looks like this:
   image=/media/hd3/linux24
     root=/dev/hdb6
     label="DSL"
     initrd=/media/hd3/syslinux.cfg

1. At the LILO login prompt hit escape
2. At the boot: prompt enter linux single
3. When the system comes up enter: passwd
4. Assign a new root-password
5. Enter: init 3
6. That's it!

Log in as root. Then issue the command:
init 1
Then:
diskdrake

• Have the network going. With Internet access via ADSL and a router you have IP adresses assigned to all machines on the local network
• Which services will be available to which machines can be configured via /etc/hosts.allow and /etc/hosts.deny.
• Which services are available is governed by the scripts in /etc/xinetd.conf, which normally attaches the scripts in /etc/xinetd.d - each script containing a mini-explanation. Restrictions on the particular service may also be coded in these scripts. Exception: vsftpd does not require xinetd!
  
• In a Windows environment you will need 3rd party telnet and ftp servers, if the machine is to be used as a server. For LINUX make sure you have the servers and clients installed that you want to use, and also that they are enabled in their respective scripts.

1. In Tab TCP/IP: Protocol DHCP
2. In Tab DHCP: DHCP-client: dhclient, tick "Get DNS Servers from DHCP".
3. In Tab Options: Tick "Network Hotplugging" and "Start at Boot".
4. Assign a host-name yourself, otherwise you get your ISP's name.

Operating Mode: Managed
Set your ESSID (from the router)
Encryption mode: Open WEP
Encryption key: Whatever you specified at the router
Set on: Automatic IP (BOOT/DHCP)

1. OpenOffice 3.1 A bit slow but very good.
2. AbiWord 2.5 is lightning fast and very good.

1. OpenOffice  has a similar interface as the old Staroffice 5.2 (which does no longer work under Mandriva).
2. Gnumeric loads .xls files correctly. It can read .csv files, and also can do a "paste values" in paste-special. All other important functions are available too, even a charting capability,

• Movie Driver: Microsoft AVI (RIFF) format
• Audio Format: 8 bit mono
• Sample Rate: 48,000 - see below!
• Video Format: MJPEG (AVI)
• Frames/sec: 8.0

1. Connect the camera via USB cable to the USB hub.
2. Switch the camera on and select "Computer" to connect to.
3. As root do mount /dev/sda1 /mnt/removable1
4. Do a cp /mnt/removable1/dcim/100k7220/* ...your picture directory...
5. Do a cp /mnt/removable1/dcim/101sscam/* ...your picture directory...
6. After that's finished switch off the camera, unmount /dev/sda1 and unplug the cable.

1. Scan the original to a file - say temp.png.
2. Open temp.png in gimp.
3. Righ-click the image and select "File" "Print".
4. Select correct printer, paper size, and scale the picture to size, then use "Center Both" to put it in the middle of the paper. Do this recursively until you are happy with the look.
5. Print it!

Playback: Master at 90%
Capture: Microphone at 100%
Switches: Do NOT tick Mic Boost +20dB - causes clipping!

1. Have your AT or meditation text split up in reasonably small chunks.
2. Record one after the other (for instance using the rawrec -h -t445 -c1 -s8000 xxx.raw command.
   For every 10 seconds recorded the file will grow by 160,000 bytes. Thus a 10 minute recording will take 9,600,000 bytes = 9.16 MB).
3. Import one after the other of these files into audacity using 16 Bit PCM, Little Endian and 8,000 Hz rate, and cut off the starting and ending clicks, then amplify it for a reasonable level and save as normal wave files.
4. Copy the lot together in the correct sequence - either with audacity or sox (the latter has a limit of 32 input files but can easily be used in a shell-script).
5. Export this file as name.mp3 if your version of audacity allows that, if not save this file as temp.wav.and convert it to mp3 format with: gogo -b 8 -v 0 -q 0 temp.wav name.mp3 (change the "b" parameter for other sampling rates!)
6. It is handy to use a shell script for the last 3 steps!
7. Put the mp3 file on an mp3 player (that you mount on /dev/sda) and play it as required!

1. Both your recordings must have the same sampling rate (44100 for CD use). If the AT recording for instance has a sampling rate of 8000 convert it with sox:
   sox -r8000 original.wav -r44100 new.wav If the music recording isn't at rate 44100, convert it too!
2. Open your AT recording in Audacity. You might want to process it first, like applying equalisation thereby emphasizing the 300 to 3000 Hz passband, followed by levelling (heaviest). Export it as wave file and exit audacity.
3. Create an AT recording of suitable length (a bit shorter than the music track) by copying it with sox:
   sox input.wav input.wav ... output.wav then open it with audacity.
4. Import Audio: Your music recording (make sure it's mono, convert beforehand if necessary).
5. Select the voice track only (left click on the track info frame).
6. Attenuate this track.
7. Listen to the recording. Change volumes of tracks as required.
8. Export as .wav or .mp3 file. There will be a message that the tracks will be mixed down to a single mono channel. This is what you want! Exit audacity.

1. Compose a simple low pitch melody in midi format.
2. Convert that to a wave file with the command timidity -Ewpso -Ow1sSl -o outputfile.wav inputfile.mid
3. Import that file into audacity.
4. Amplify the sound (no clipping).
5. Split stereo tracks (from the track name menu).
6. Change pitch down on ONE of the tracks by 0.5 - 3% (experiment with that value).
7. Export this file as name.mp3 if your version of audacity allows that, if not save the file in Microsoft 16 bit PCM WAV format.
8. Convert it to mp3 format with: gogo -b 8 -m s -v 0 -q 0 temp.wav name.mp3 giving you a REAL stereo mp3.
9. Alternatively convert the wav file to mp2 format with ffmpeg -i temp.wav -acodec mp2 -ac 2 -ar 44100 -y name.mp2
10. You can put the mp3 file on an mp3 player and play it using headphones during meditation!
    Your mp3 player may also play mp2 files if you change the suffix to mp3, depending on the software version of your player!

Download from http://www.alsa-project.org/~james/sound-fonts/8MBGMSFX.SF2
the file 8MBGMSFX.SF2 

Edit /etc/rc.d/rc.local and add the commands:
pmidi -l >/dev/null
sfxload /i586/8MBGMSFX.SF2
... Make sure that "pmidi" and sfxload are in /bin - NOT /usr/bin !!
... of course substitute your own directory for the 8MBGMSFX.SF2 file!
The pmidi -l command is required, otherwise the sfxload won't work! 
Without the sfxload there will be no midi-output.

This concludes the installation. 
To play midi files, execute pmidi -p 17:0 name_of_a_midi_file
Or create the following script plmidi in your $HOME/bin file:
#!/bin/bash
pmidi -p 17:0 $1
exit

Note that only ports 17:0 to 17:3 allow sound to be heard!

Bug: pmidi cannot handle lyrics events! 
Before playing any midi file with lyrics, edit these out with the "event list editor" of Rosegarden.

Kmid works as well if you configure Midi accordingly! 

Note: On another PC I used the same procedure for a Soundblaster Audigy card.
The only difference is that pmidi-l gives you:

... any comments ...

• Gutenprint does not know the Canon PIXMA iP1300 printer, thus gimp cannot print graphics with it, since in gimp there is no possibility to print without Gutenprint...
  Work-Around: Use mtpaint for printing graphics. This gives excellent quality - better than xpaint.
• Xpaint sometimes saves an empty graphic when using "Save".
  Work-Around: Always use "Save As" and specify explicitly the file type instead of "Save".
• Xpaint loops when the window is maximised.
• The nvidia driver of xorg.conf does not allow video capture nor still image capture.
  Remedy: Replace the "nvidia" entry in xorg.conf by "vesa" whenever you want to do capture.
  However colour quality on playback is awful with the vesa driver but good with the nvidia driver.
  Switching drivers can be done with 2 trivial scripts "xorgvesa" and "xorgnvidia".
• The s3 driver of xorg.conf (since my nvidia video card gave up, I now have an old 2 MB s3 video card) does not allow x to start (lock-up on black screen, Alt-F4 gets one back to the command prompt).
  Remedy: Replace the "s3" entry in xorg.conf by "vesa".
  However maximum achievable resolutions are:
  Colour-depth 24: 800x600.
  Colour-depth 16 and 15: 1024x768.
  Colour-depth 8: 1280x1024. But with this colour-depth neither Firefox nor Seamonkey nor Netscape 9 will start. The only usable browsers are Opera (V.9.64) and Dillo-2.0-1.
  Another idiosyncrasy with this card is that you have to start the system up using VGA=0 at the LILO boot prompt. If you don't, you will not see the full display when leaving X and going to the command prompt!
• Xcdroast-0.98-37.alpha15 and previous versions cannot blank a DVD+RW.
  Remedy: Use k3b instead!
• Mozplugger 1.8.1 does not handle the <object> tag. The <embed> tag in contrast is handled correctly!
  Remedy: Use Mozplugger 1.10.1 instead!
• OpenMotif does no longer provide a window list (f.window_list not implemented - a retrograde step from LessTif).
  Work-Around: A window list can be simulated by 2 scripts:

  $HOME/bin/wlist:
  #!/bin/bash
  xlsclients | wlaf
  read dummy
  exit
  
  and $HOME/bin/wlaf:
  #!/usr/bin/tclsh
  while {![eof stdin]} {
  gets stdin xlsline
  if {[string length $xlsline] > 12} {
  puts $xlsline
  }
  }
  exit
  
  In $HOME/.mwmrc add in "Menu DefaultRootMenu" the line:
  "Windowlist" f.exec "xterm -e wlist &"
  and in "Menu DefaultWindowMenu" the line:
   Windowlist _w Alt<Key>F12 f.exec "xterm -e wlist &"
  
  This gives you a windowlist, however to switch to a particular window you have to Alt-Tab through them! 
  

• xlsclients ignores some windows (for example "nedit" ones). This is the reason why the above scripts for mwm do not show all active windows.
• Opera Version 10 shows a segmentation fault when run by a non-privileged user. Work-Around: Use version 9.64.
