Uhh thanks but that's kinda missing the point of this - that I don't
want binaries from random people on the internet.<br>
<br>
I need to know how to extract it from the bios update files, not the
bios already on the EEPROM.<br>

<pre wrap="">I have the IFD and ME from an x220 that I recently flashed with coreboot

with the coreboot ROM I subsequently flashed. Can zip and send via email,

Those might have a length too long to fit a flash so you need to trim

<pre wrap="">those down before using ifdtool on those (If they contain and ifd of

so depending on size of rom
dd if=FL1(or 2)file of=vendor_bios.rom bs=1 count=xM

<pre wrap="">It didn't work :( after that still "no flash descriptor found in this

These are the files and the flash chip on the board is 8M
8523776 '$01CB000.FL1'
8523776 '$01CB000.FL2'
8523776 '$01CB100.FL2'
All of them have different hashes, but I do not know what makes them
different (maybe it is for various board revisions?)

<pre wrap="">EC are only accessed trough port mapped IO (or on newer ones also via
memory mapped IO). EC itself does not have DMA afaik.
