edmann.com 2.0.1 alpha

I am copying this verbatim from muzso.hu website. I am posting it here because one it's easier for me to find in the future, second things seem to go away on the web. And who said it was forever. :-)

Prerequisites:

• dd
• qemu
• a DOS floppy image, e.g. balder10.img

Procedure (assumptions for this description: balder10.img is in CWD, stick appears as /dev/sdc):

• Insert memory stick (Caution: all data on this stick will be destroyed)
• Find out device name (e.g. /dev/sdc)
• Make sure it's not mounted (check with mount command)
• Clear the MBR:
  
  dd if=/dev/zero of=/dev/sdc bs=1012 count=2
• Boot qemu:
  
  qemu -curses -boot a -fda ./balder10.img -hda /dev/sdc
  The -curses option will make it run in text mode.
  (This way you can run qemu easily eg. over an ssh connection.)
• Answer all questions with their default values
• At the A:\> prompt:
  
  fdisk
  (create a bootable, primary DOS partition)
• Stop qemu
• Remove memory stick and re-insert it.
• Make sure it's still /dev/sdc, otherwise use new name in the next steps.
• Make sure again that it is not mounted.
• Boot qemu:
  
  qemu -curses -boot a -fda ./balder10.img -hda /dev/sdc
• At the A:\> prompt:
  
  format c: /s
• At the A:\> prompt:
  
  xcopy a: c: /n /e
• Stop qemu

Done! Now you can mount the stick again and copy any required utilities on it ...

So i want to record the audio from my pc, this is the internal audio, not from an external source. So i found Jordi Carrillo's site that had the commands that i can use in Fedora Linux. I am posting the commands that i would user here so i can find them easier next time.

alsamixer

Once there, select the capture view by typing the tab key. You’ll get the next screen:

With the arrow keys select the column Capture and set it to the CAPTUR mode with the space key as in the screenshot. Adjust the recording volume with the arrow keys. You can also set it up with the gnome volume control panel going to the capture tab.

Recording sound to an mp3 file

You’ll need the lame mp3 encoder. Install it by doing

Recording sound to an ogg file

You’ll need the oggenc (the ogg encoder). Install it by doing

sudo yum install vorbis-tools

Type the following command

arecord -f cd -t raw | oggenc – -r -o out.ogg

And you’ll get your sound recorded to an ogg file. Take into account that we record directly to a compressed file, so there’s nothing in between, so you can record for hours saving an incredible amount of hard disk space.
