In order to have DOS and NetBSD coexist on the same drive, you need to
follow the instructions in the INSTALL document exactly.  Which is to
say:

1) Use FDISK and FORMAT under DOS to create and format the DOS
partition.  Make sure you give FORMAT the /S switch to make the
partition bootable.

2) Use pfdisk under DOS to create the BSD partition, and give it ID
code 165.

3) Install BSD, and give it the correct size and offset for the BSD
partition.

If you run fdisk /mbr under DOS, that should wipe the BSD boot stuff
from the hard drive and let you boot from the DOS partition, assuming
it is (a) marked as active in the partition table; and (b) set up to
be bootable (IO.SYS/MSDOS.SYS, etc.).  I'm not sure if the BSD
partition needs to be marked active after step (2) above, but I've
always done so just to be safe.
