The only problem with that is that I can't even get to the point where I can type that in. I'll try again though. Using iATKOS v7.

EDIT: I guess I wasn't pressing it early enough. Now I get the lovely anti symbol, and the computer doesn't go further than that.

EDIT2: Did a -v -x cpus=1 and got through, then "Still waiting for root device". Noooo!!!
