I've been looking at a LOT of examples of partition tables. I notice
that there is some discrepancy on what the final cylinder is on the d
partition:
cylinders: 3148
d: 3173184 0 unused 0 0 # (Cyl. 0 - 3147)
or
cylinders: 484406
d: 488281250 0 unused 0 0 # (Cyl. 0 - 484406*)
My understanding would be that since you are counting from "0" to the end,
the final cylinder would be [total cylinders - 1]. However, that asterisk
perhaps modifies the meaning?
Related to this question, when annotating adjacent partitions, I would
think that the beginning of the next partition would be 1 plus the
final cylinder of the previous partition. However, I often see, e.g.:
e: 1311660 1230453 4.2BSD 1024 8192 43728 # (Cyl. 1302*- 2690*)
f: 98280 2542113 4.2BSD 1024 8192 16424 # (Cyl. 2690*- 2794*)
Again, the asterisks define some point between a cylinder boundary??
