[ale] Using PXE to boot Live Ubuntu CD

[William Fragakis]

I'm learning things here.... appreciate the response.

I was looking at various ubuntu docs and at times they append ip=dhcp rw
(after nfsroot). Does that make a difference? ie without does the pxe
kernel know to go out and get an ip address and having failed that can't
find the nfs server?

I've seen something similar (iirc) when trying to netboot a box with two
nics and the wrong nic tries to go get an ip address and fails because
it's disconnected - that was a while back so my memory may be faulty

I don't have the old emails that started this thread, so again,
apologies if this has been covered.

And, again, nice thing you are doing to personally help out.

Regards,
William
