from the top of my head that would be
lib/core/lib-blockdevices-filesystems.sh and
lib/core/lib-ui-interactive.sh

have a look at the grub functions and how they relate to each other,
and how they are called from the interactive and automatic
procedure, namely by worker_install_bootloader(), you'll see.

You can also check Pythers' syslinux work, 
https://github.com/pyther/aif
it might give you some more insight in what needs to be done to add
support to a bootloader, although i haven't reviewed that code properly
myself yet.
