I would start looking at exec_netbsd() in sys/arch/i386/stand/lib/exec.c.
This is used by both i386 and amd64. Presumably the failure is occuring at
some point during the execution of this function.
exec_netbsd() ends up calling startprog() which is defined in
lib/startprog.S, which incidentally would be a good place to put the code
You could use printf() in the boot loader just as easily, but if it's
resetting and clearing the screen instantaly perhaps dobeep() is a better
It has been 10+ years since I built the bootloader by hand but I think it's
a case of running "make" in sys/arch/i386/stand or some variation thereof,
and if I remember correctly the executable you're looking for is "boot".
