Read the man page. Okay, the difficulty though is that I had clobbered my boot manager with a Win2K install (dual-booting) and the CDROM doesn't give you the boot0cfg command. I had to install onto a 2nd hard drive and then boot into that instance of FreeBSD and use boot0cfg from there. It'd be nice to have the option of doing that from the CDROM.
