    old.

    Can I use new with the 20267? According to config help and the source
    code I looked at the 20267 is not listed as one of the devices for new.

    I haven't tried that yet (mainly cos it's a bit of a pain - I have 3
    devs connected to it, inc boot stuff - and i didn't know if it'd be
    really useful info) but I will if need be. Just shout.

    I have tried going fron hdd to hdh but nothing bad happened. It's only
    when going from hde to hdh that fun occurs.
