I just started Knoppix & Morphix from CD and both run like a charm. Now why
would it run slower from a hd install then it runs from CD.
I don't have the answer but maybe one of you guys know why that could be.
My current install has a 2G swap on /dev/hdb6, 5G / on /dev/hda and /var /
home /usr on /dev/hdb5 thru 9
