Fetching bootloader from network location

[Jeffrey Finkelstein]

I have been charged with the task of determining whether it is
possible to boot from a network location without using PXE, and I
would like to know if anyone else has any information on the subject.

Essentially the task is this: Given a Mandriva boot.iso CD-ROM image,
is it possible to edit one of the isolinux.cfg entries so that when a
system boots from the disk, the isolinux bootloader fetches another
bootloader from a tftp server, essentially chainloading from a network
location? I can't seem to find a way to put this sort of thing into
action.

The best resource I've found for this is a website describing the
automatic install process for Mandrakelinux:

Has anyone seen anything like this?

Cheers,
Jeff
