I suspect the instructions are the part that's broken here. d should
always begin at offset 0 and be the whole disk (that's what ends up
getting used anyway, since it's RAW_PART), but c is only the NetBSD
portion of the disk, and should agree with the NetBSD partition's
boundaries in the MBR ("fdisk") partitioning. I suspect this is what
the "slice at 63, c at 0" complaint is about, and that the instructions
are broken for telling you to make c and d identical.
As for whether 63 is the right number, I can't say. I'd have to ask
someone who knows the RAID stuff.
