[quote="Dave_Bechtel"]--Good to know. Did you manage to get all the data copied off the 6.8?

Yes thanks; it was all accessible to my other OSes anyway. ( I now reckon that the 6.8 would have worked in position hdc for Knoppix if I had changed the BIOS to manage it in LBA mode. However it has gone to a good home; I've used it in a PC that I have built for my daughter.)
BTW this has reminded me what a pain in the **** W98 is to install compared to most Linux distros.
