me_cleaner haswell

[Claudiomfa]

Hi @corna ,

I have this toshiba l50-a-165 (vgst/vgstg motherboard - I5-4200u Haswell) and i have done me_cleaner on the bios dump and effectivelly removes all intel management engine interface but dont remove the 30 minutes shutdown.

Anyone can give me some solution? the notebook works very well except the 30 minutes shutdown. i have tried many bios dump and no one solve my problem.

Thanks

Hi @Claudiomfa,

Is there a BIOS image (containing a ME image) available on the manufacturer's website? Can you also provide the output of intelmetool -s (available on the coreboot's repo)?

@corna

On this link i attached the manufacturer's website files and a dump.

http://cmfa.duckdns.org/cloud/public.php?service=files&t=b2806d052d97630ab2422ad25178f799

In relation of intelmetool can i use them in windows or i have use that on linux?

[corna]

Linux
If you don't have it, I suggest you a distro with a kernel < 4.4 to avoid possible problems on newer kernels

@corna

How can I use that comand in ubuntu 14.04 lts?
where I can download the intelmetool files?

[corna]

 $ sudo apt-get install libpci-dev 
 $ git clone --depth=1 http://review.coreboot.org/p/coreboot
 $ cd coreboot/util/intelmetool
 $ make
 $ sudo ./intelmetool -s

@corna this is the result of intelmetool. That result with bios me_cleaner done

Bad news, you have a Lynx Point-LP LPC Controller so you have ME hardware on board and you can't control or disable it, continuing...

From the output of intelmetool it appears that:

• The FPT is damaged (wrong checksum)
• ME is disabled and is in the 30-min window

However the input files are good, and the cleaning process seems OK. Can you check if the flashed ME image is identical to the input one (flash, dump again and do a diff between the original and the dumped)?

@corna can you elaborate on the iomem=relaxed you mention for kernels >= 4.9 as my output is:

user@host:~/coreboot/util/intelmetool$ sudo ./intelmetool -s 
Bad news, you have a `QM67 Express Chipset Family LPC Controller` so you have ME hardware on board and you can't control or disable it, continuing...

Error mapping physical memory 0x0000004275159040 [0x4000] ERRNO=1 Operation not permitted
Could not map MEI PCI device memory

Where do I specify that iomem config value?

[corna]

It is a kernel parameter, so it should be added in the GRUB configuration:

/etc/default/grub

 [...]
 GRUB_CMDLINE_LINUX_DEFAULT="iomem=relaxed ..."
 [...]

Then regenerate the GRUB configuration with sudo update-grub

Hey, how to run me-cleaner ? it has no .bat or .exe files

[persmule]

it has no .bat or .exe files

It does have .py files, so you should try to leave the bottom of the M$WIN and learn how to run them.

i wouldn't recommend trying to do something to your computer that can potentially brick it if you don't know how to fix it. if you don't even know how to run a python script, how are you going to be able to unbrick it if something goes wrong?
