The computer in question is another one, but here is your list modified
Total cylinders 10000
hda1 primary cylinder 1 - 100
hda2 primary cylinder 101 - 1000
hda3 primary cylinder 1001 - 2000
hda4 extended cylinder 2001 - 5000 [was 10000]
hda5 logical cylinder 2001 - 2500
hda6 logical cylinder 2501 - 5000
free space cylinder 5001 - 10000
Can you visualize it now?
I have scanned the some LVM doc's and it mostly went right over my head, maybe
I should spend a bit more time on it. Too late now I guess.
