Just doing the disklabel -w -r followed by the disklabel -B is creating
a dangerously dedicated disk, which your BIOS apparently doesn't like.
(See the first hex dump you did, where boot1 has ended up in the MBR.)

That's why installing boot blocks is messing with the partition table,
to answer the question you asked elsewhere.

You need to dd and fdisk before the disklabel commands, which will give
you a standard partition table (at the cost of 63 sectors of disk
space).
