That sounds very interesting and hopeful.

OK. Point taken.

Ah! I didn't realise that! I'll try it in a minute after reading my email.

Not noticeably. Certainly on booting up it only finds hdc and hdd.
The install program only shows /dev/hdc and /dev/hdd when it asks about
installations discs, but I'll look for /dev/hdd1 etc in a minute.
