Thanks, for the response. I kind of put this one off for awhile. I just
really wanted to test out FC3 on my hdf drive before moving upgrading
hde. I am basically getting a kernel panic when trying to boot off
FC3. In my hardware browser hdf2 says "LVM Physical Volume". I also
cannot mount hdf2, but I can mount hdf1 when logged into my FC2 hard
drive. Let me know what you think about this.
Thanks,
Chris.
