I tried the current Coreboot version and initially failed. Both the BX 
code and my self-written code are unable to start.
I took the P2B Asus board as a basis and adapted it. Romestage seems to 
be going well.
Postcar is still found but not executed. The storage areas may not be 
correct or are calculated incorrectly.

Good idea :)

I can hardly imagine it. There are a lot of registers on the BX that 
don't exist on the LX.

I'll start a new thread next week and make all the logs available.
It would be great to get LX boards working.
