How to update masterboot

Hi all,

I modified the /usr/src/boot/masterboot.s and make it successfully.
But how can I get my new binary run? Someone told me that I can use
installboot, but it didn't work, I used it as follows. What's wrong
with it?

===========
under /usr/mdec:
installboot -m /dev/c0d0 masterboot
===========

Thanks,
BingQian
