Every time I try to boot up Knoppix it tells me "unknown bus type 2" and will not let me boot it. I tried to go to the bios but could not find a way to turn of the plug and play. Someone told me that is what I needed to do for it to boot. I have a Sony VAIO PCG-GRT170 Notebook. Please help me I would like some advise on what to do to get Knoppix to boot. My computer already is set to boot from cd first.
