Intel X550 Issue - SIOM Module

[3rased]

Thanks for all your assistance. During quite a bit of messing around today I came across the following git repo in a google search: https://git.rthoni.com/robin.thoni/ipxe/src/master

I replaced all intel drivers from the official source with intel drivers from the above repo and the issue no longer exists. Things now work correctly and no more issues with embedded scripts!
