I'll stick to coreboot + SeaBios as I can boot linux/windows which perfectly
fine and the installation seems to be easier and I can't see any reason why
switching from (Sea)BIOS to UEFI.
One additional general question regarding the flashing on X230s.
Most howtos include that it is sufficient to flash only the upper 4MB BIOS Chip
and leave the 2nd 8 MB BIOS Chip untouched.
After creating my 12 MB Coreboot.rom I split it and use only 4MB for flashing.
See also the Coreboot Wiki at
https://www.coreboot.org/Board:lenovo/x230#Hardware_Flashring
"(...) Write the flash. Since you have to write only top 4M, first split out
those 4M:
dd of=top.rom bs=1M if=build/coreboot.rom skip=8
Use flashrom to flash top.rom (...)"
As far as I understand the 2nd Chip include the Intel Mangement Engine (ME),
shouldn't this chip also touched and (at least party) ME'cleaned?
Or is the 2nd BIOS not used at all after flashing Coreboot to the top 4MB chip?
