I have a similar issue. I was just given an older ThinkPad and want to install Knoppix. It's hard drive is just under 2GB and the installer won't let me go forward with the install. Is there a way to pick and choose some of the application and get past the installer warning? I tried the suggested IGNORE_CHECK=1 sudo knoppix-installer but it brings up a list of what it's going to do (I think) and then when I click next, I get back to a blank prompt. Weird.

I know that I can do a poor-man's install (and I've done that) but it's just too darn slow. Any suggestions? I've also tried VectorLinux and Slackware installs, but they both are choking and not functional. Knoppix works both from the cd and the poor man's install. I just want to do a full install. Any thoughts?
