it looked like a nice answer to my problem but my problem seems to persist.
I am in fact trying to boot a fedora-dvd but this didn't work at all. So I put the filesystem on the harddisk with knoppix.So I could put the fed*dvd directly on the harddrive.
Strange thing, knoppix recognises the cd of knoppix in the dvd rom but if I start the computer with the cd player. I cannot mount the dvdrom in knoppix. so i tried
dmesg | grep -i cd
problem is I only find the hda and hdb but no line like sr0 or sr1. I tried different mount points and different device names but none of those in the shown list seem to work. Is there an other way to get my dvdrom bootable or to get the iso file on the harddrive.
First thing I'll try to do now is to flash the bios. May be that'll give me a fair chance. If any possibility, please tell me
