[coreboot] R: Re: BIOS log in coreboot

[ingegneriaforense at alice.it]

Thank very much guys !

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.

Hi Vincenzo,
 
I had the same issue just a day ago and solved it with cbmem
 When building coreboot, make sure you have selected the "Send console output to a CBMEM buffer"-option (Run `make menuconfig` and select `Console`) and then use the `cbmem` tool (in `util/cbmem` in the coreboot git repo)

 
Have a look at the following page https://www.coreboot.org/Cbmem_console
 
Greetings,
 Felix

Hello Guys !
  
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.
