ipxe.org is mostly documentation, I can agree that it can be hard to
navigate and find what you are looking for sometimes, but most information
There is also forum.ipxe.org which has this question and many others asked,
and in most cases also answered.
To start with your question about Live CD - you probably don't want to load
the ISO into memory and then try to boot it even if iPXE can do that. One
of many posts that explains why it probably won't work as you expect can be
found at: http://forum.ipxe.org/showthread.php?tid=9314&pid=14693#pid14693
Loading anything large-ish over TFTP is probably a bad idea just because
it's slow. One of the best parts with iPXE is it's high performance http
support, so strongly suggest to use that.
I don't remember the exact details but path access mostly works relative,
if you just run chain filename, it should use tftp with the server ip given
via dhcp, which is stored in the next-server variable. I can recommend the
config command to check around which settings exists.
