Thanks! For some reason I expected the option to be in the menu that pops up when I press the ThinkVantage button but last night I dug around and found it under the Start menu.
Tonight I'll pick up some CDs and make a set for safekeeping!
Got a new Thinkpad z60m right before I left for the holidays - took it with me and tried to partition the drive with Knoppix. Got the drive partitioned but then the ThinkVantage button stopped working. I didn't have net access over the holidays so was flying blind - so I managed to get to the point ...
