[SOLVED] LoadImage in efi_image_probe fails on Lenovo ThinkPad Yoga 11e

[SebastianRoth]

OMG... We found out what the issue is/was. Too bad that we didn't check ALL the BIOS settings earlier. On that Yoga (and most probably on other models as well) there is a so called Embedded Security Subsystem chip. Disabled and now LoadImage works like a charm. Funny that it does not prevent iPXE from being loaded in the first place.
