The images I suggest you try are in images/alternatives/. The specific image I would try is cdrom.img-2.2.19-BADZ5. Use rawrite.exe to create the boot disk if you are making it in dos. Use dd to create the boot disk if you are making it in unix/linux. Good luck! -- tlyons at mandrakesoft dot com http://www.linux-mandrake.com/en
