Yup, by now i figured that out ...
I asked mike how to get my hands on that image file via email, no response yet, i think he's busy :-)
I succesfully installed mulinux on two disks, attached the empeg HD to my PC and booted mulinux from disk.
After that i was able to mount my FAT32 Disk and the empeg partition containing the good stuff ...
So i was able to backup all files to my PC, used ID3Renamer ->
Voila a nice Folder with nice named, nice tagged mp3 files :)

Now i just have to wait for my 12 Gig drive ...

P.S. Thanks for all that help, only the image is missing now ...
