Did you also copy /usr/mdec/boot to the rsd0a file system?

Is it actually a ffsv2 filesystem? You can check with:

# dumpfs /dev/rsd0a | more

and the output should start like:

file system: /dev/rsd0a
format  FFSv2ea
endian  little-endian


(or "format  FFSv2", that makes no difference to the bootloader).
