RedHat 9

I again tried to compile rio500-0.8.1, but without success. Compiling fails under kernel 2.4. This is an unresolved issue and mentioned in the discussion forums. So I installed the Rio500 package rio500-0.7-1.i386.rpm. Interestingly I managed via the command line to

a) format the internal memory: rio_format
b) create a folder (which is necessary before one can upload a song): rio_add_folder c) upload mp3s: rio_add_song ). That's a big advantage to the crappy Windows Rioport interface. Next time I try to install the Gnome GUI.

Usually you change the default runlevel by editing /etc/inittab. However, sometimes you boot into runlevel 3 (e.g. by selecting safe mode from the grub menu) and then want to change to runlevel 5. This you accomplish on the fly with the command: telinit 5

To dump a disk (or a partition) into a file, you use the following command:

dd if=/dev/hda3 of=file.bin

This command writes the complete data on the hda3 partition into the file file.bin.
To mount the filesystem that is in the file, you need to create a loopback device:

losetup /dev/loop0 file.bin

Now you can mount the filesystem as usual:

mount -r -t filesystemtype /dev/loop0 /mnt/mountpoint

Apparently, one can combine the last two commands into one:
