check the old bootblocks
/usr/src/sys/i386/boot/biosboot for README.386BSD, README.MACH,
README.serial for some background.
then try find documentation (good luck) on the NEW bootblocks
/usr/src/sys/boot/README is a start.
The kernel starts in /sys/i386/i386/locore.s (at btext I think)
then goes (from memory) to main() via mi_startup (I think).
mi_startup is in init_main.c.
mi_startup calls all teh initialisation modules linked into the kernel.
(see kernel.h)
eventually it starts up init..
