If you can boot from the harddisk, you obviously have a NetBSD
filesystem on it. I guess you have installed it at the beginning of the
disk. The boot code assumes exactly this if there is no NetBSD entry
in the BIOS partition table.
When you try the NetBSD partition ID, this entry seems to point to

There was no change in the kernel calling parameters, there must
be another reason.

You should be more specific.
As I said, the BIOS partition table entries seem not to match
reality. You should solve this first.
Be sure to use the correct drive geometry as used by the BIOS
(perhaps use the DOS "pfdisk" program) and to have 1 free track
at the beginning of the disk for the boot selector.
