Hi Vincenzo, The command is called "cbmem" and it may be part of a coreboot-utils package in distro or failing that you can use it from the utils directory from git cloned coreboot.

Please, I've understood the use of cbmem, however, my question is: how can I read this log from the operating system ? That is, my PC has finished to boot and Linux has taken the control of the machine. In this situation I want to read the coreboot bios log. Is it possible this? How can I do ? Which linux command I need to use to read it ? Or where this log is stored in the filesystem ? Thanks in advance, Vincenzo.

I apologize with you if my question seems silly: can you tell me if Coreboot stores a log of the POST phase in its EPROM memory ? If so, is it possible to retrive the log by the Operative System and read it ? Thanks in advance. Vincenzo.
