Hi Tristan,

Thanks for the info - where do I find the firmware? Is it in the Xen
hg repositories?

I was hoping it would be a walk in the park to build, but I kinda feared
you would say that. Do I need a special environment to build it, like a
special pre-historic version of GCC running on RHEL 3 or something like
that?

Cheers,
Jes
