fdisk plays with DOS (windows) partitions. There are 4 of them.
disklabel plays with OpenBSD partitions. There are 16 of them.
This is from a Lenovo T43 booted from 2G USB drive.
Fdisk partition 0 (DOS fdisk will call it partition 1) Dos partition
This is the same disk as disklable partition i (sd0i)
There is also fdisk partition 3 (DOS fdisk would call it partition 4)
OpenBSD partition.
The OpenBSD space is sd0a and sd0b
The c partition refers to the entire disk regardless of who does or does not
own any part of it.

(This is after several rounds of messing around including completely zeroing
the drive,
so the disk "geometry" may be the worst possible. So far it seems to work,
kinda slow)
