Intel X550 Issue - SIOM Module

[NiKiZe]

That is a repo created 2 years ago by just adding files, and then the keymap was modified. (No other history exists)
So based on that I would assume that a 2 year old-ish commit of iPXE should work as well...
Now with that as a base it would be good if you could do a git bisect
Or at least try to find out which commit that is.

However then again there is no logic behind this issue at all... especially if you have been running with snp.efi - since that build does not contain any intel drivers at all.
