FreeBSD 3.2-Release:
/usr/src/sys/boot/i386/boot0
Note: this is one of a zillion of boot managers that do this.
Note2: you only get 512 bytes loaded in from the MBR or 0 level boot.
This is BARELY enough to use the BIOS calls. You use this to load the
level 1 boot which is usually about 8K, and even it still uses the bios
calls, due to the evil keyboard IO, disk IO remapping, etc. etc., etc.
that the BIOS does.
