I've got a copy of Knoppix 3.3 on CD, and have tried to boot it from an IDE CDROM drive on a machine which has no other IDE devices (its drives run off an AIC7xxx SCSI card). I'm getting the previously-described error message, which I figure is surprising since it has a standard IDE CDROM.

I have another server with matching hardware config, and think I need to boot with "knoppix ide2=xxxx", but what do I use for xxxx ? Can I look this value up on my other Linux box ?
