I have a similar issue trying to boot 6.7.1 and I think I got a bit further. This is a desktop with two SATA DL DVDRW, two SATA HD and a combination CF, SD, floppy. When I boot from the CD, it loads partway and them gives me a message saying that it cannot find "KNOPPIX". If I copy the contents of the CD to a CF card, the machine boots from the CD and then loads KNOPPIX from the CF card. Once it is up and running, I cannot access any of the SATA devices.

Any suggestions appreciated.

Thanks
