Can Knoppix run diskless? I didn't see hard disk mentioned in requirements. But it sure does probe /dev/hda and finds HITACHI_DK227A-50. That disk is messed up; it had Windows installed on it. If /cdrom/KNOPPIX/modules/insmod tried to access /dev/hda, that would explain the I/O error. I tried the boot parameters myconf=/dev/hdb, home=/cdrom/knoppix.img (mount reported that /dev/hdb gets mounted on /cdrom), and noscsi. No difference.

Questions: what does that error (/cdrom/KNOPPIX/modules/insmod: I/O Error -- Can't find KNOPPIX filesystem, sorry.) mean?

How do I tell Knoppix to leave my hard disk alone? (The existence of a noswap boot parameter is a hint that by default it would use the hard disk.)
Boot param? Get screw driver and take disk drive out?

Thanks
