Yup! thats it!

The bootable file has encoded into it all the configuration and
booting info as well as the executable text. The btl file is an
unstructured binary file from the point of view of iserver. The
iserver just sends the file down the link. The file is structured
into packets (as I understand it) by bootstrap code as it passes
into the network and is fanned out. All control lies with the
code in the bootable. The iserver does not have a clue.

I hope that answers it. If you have any further queries, email me
and I will do my best...

Cheers
