If I'm not mistaken, it goes like this.  Starting with C:

- The primary partition on each disk, in order
- The logical drives mapped in the extended partition, in order, on each 
  disk.

If you were planning to use logical drives, I'm not sure NetBSD will 
recognize any past the first logical drive in an extended partition.
