I just compiled it. Anyone has pictures where is EEPROM chip located so I can hardware flash if I brick my machine?
If the x2100 is anything like the x210 you don't need to hardware flash. Coreboot can be flashed via software with

Code: Select all

flashrom -p internal -w coreboot.rom
I will definitely need hardware flash after I [censored] it up. I will be flashing internally, but I will most likely brick it with a bad coreboot build soon enough.

Can someone with a working Intel ME (meaning BIOS->Advanced->PCH-FW Configuration does not show ME Firmware Version 0.0.0.0) send me a full dump of their X2100 Bios?
Preferably done via hardware flasher, so we can be sure the ME Region is fully dumped.
I'd like to take a look at it.

Thanks alot

I do not have fully working ME, but the complete BIOS is available, you don't need a dump.

ME is finicky, I believe I need the initialized configuration data from the ME Partition of the BIOS to reset the ME, and I'm not sure that is contained in the published BIOS.

Why do you need it?

Btw, I see some differences 0x00004216bb and forward, so there is something initialized there.

@lemoniter
I am trying to ascertain if my ME is even running.

Can somebody run this:

Code: Select all

git clone git@github.com:exander77/intelmetool.git
make
sudo ./intelmetool -m
And post the results.
