The 'mbr' boot code can only output to the bios console device - which is
why the error message is output there.

You haven't given the output of 'fdisk wd1' or 'disklabel wd1', but the
text 'No NetBSD partition' ought to be a clue!
The 'mbr' code has booted the active partition, but the netbsd code in that
partition has failed to find a valid netbsd partition in the MBR [1]

I suspect that you haven't set the partition type to 169 in fdisk.

[1] yes, it has to re-read sector zero and search the mbr partition table
again in order to find the sector number it was read from.
