After building a new boot loader, you will need to use installboot(8)
to actually install said code into the system. Your `make install`
merely placed the bootloader into the spot in the filesystem where
installboot expects to find it, but won't do the special editing of
the disk that installboot does.
(but also see the replies from others about ttys(5) to deal with your
situation without potentially screwing up your entire system with a
faulty bootloader)
