Welcome sir! we are always pleased to see new users and companies using
coreboot - please feel free to ask any and all questions.

Coreboot will be a secure and affordable choice for what I presume is
your application.
if you wish to use coreboot in a production environment it might be a
good idea to inquire with your board vendor as to if you can save money
by purchasing "raw" boards without the usual AMI/Phoenix firmware/licenses.

If your company permits I would suggest posting the board model, .config
file, etc whenever you have an issue as the wiki advises - remember sure
to remove identifiers such as MAC address and serials.

I would suggest emailing the people behind the HEADS project such as
Trammel Hudson - AFAIK they are the only ones currently doing major
coreboot related TPM work and would probably be willing to provide some
assistance...
