Hey everyone,
currently I working on a x220 to flash coreboot onto it. I notice that my x220 has a current BIOS version from 2011 (1.24 UEFI/BIOS and 1.13 ECP).
Within the change-log[0] variates updates and fixes are stated. Including changes to the ME engine. Within many documentation part of coreboot, it's stated, that the ME part can't be written. Here my question: Should I update the BIOS to the latest release before flashing coreboot onto it?
There is for example this note:
If the UEFI BIOS has been updated to version 1.43 or higher, it is no longer able to roll back to the version before 1.43 for security improvement.
Could this cause problems? For example the CVE-2017-5715 (Spectre) would be fixed. I expect them to run role out the microcode update from Intel... so might be no problem to coreboot, right?
best regards, akendo
