This was originally done on the +ThinkPad X200, and later adapted for the ThinkPad R400/T400/T500. It can +in principle be done on any GM45 or GS45 system. + +The ME is a blob that typically must be left inside the flash chip (in +the ME region, as outlined by the default descriptor). On GM45, it is +possible to remove it without any ill effects. All other parts of +coreboot on GM45 systems (provided GMA MHD4500 / Intel graphics) can be +blob-free, so removing the ME was the last obstacle to make GM45 a +feasible target in libreboot (the systems can also work without the +microcode blobs). + +The ME is removed and disabled in libreboot by modifying the descriptor. +More info about this can be found in the ich9deblob/ich9gen source code +in resources/utilities/ich9deblob/ in libreboot, or more generally on +this page. + +More information about the ME can be found at +<http://www.coreboot.org/Intel_Management_Engine> and +<http://me.bios.io/Main_Page>. + +Another project recently found: <http://io.smashthestack.org/me/> + +[Back to previous index](./). + +</div> + +<div class="section"> + +ICH9 gen utility {#ich9gen} +================ + +It is no longer necessary to use [ich9deblob](#ich9deblob) to generate a +deblobbed descriptor+gbe image for GM45 targets. ich9gen is a small +utility within ich9deblob that can generate them from scratch, without a +factory.bin dump. + +ich9gen executables can be found under ./ich9deblob/ statically compiled +in libreboot\_util.

Alternatively, if you are running libreboot already (with the +correct MAC address in your ROM), dump it (flashrom -r) and read the +first 6 bytes from position 0x1000 (or 0x2000) in a hex editor (or, +rename it to factory.rom and run it in ich9deblob: in the newly created +mkgbe.c will be the individual bytes of your MAC address). If you are +currently running the stock firmware and haven\'t installed libreboot +yet, you can also run that through ich9deblob to get the mac address. + +An even simpler way to get the MAC address would be to read what\'s on +the little sticker on the bottom/base of the laptop. + +On GM45 laptops that use flash descriptors, the MAC address or the +onboard ethernet chipset is flashed (inside the ROM image).

Alternatively, gs45 (if raminit is +taken to be the only issue with it) can be part of gm45 northbridge +support (and X200S/Tablet being part of the X200 port) with conditional +checks in the raminit that make raminit work differently (as required) +for GS45. nico\_h and pgeorgi/patrickg in the coreboot IRC channel +should know more about raminit on gm45 and likely gs45. + +pgeorgi recommends to run SerialICE on the factory BIOS (for X200S), +comparing it with X200 (factory BIOS) and X200 (gm45 raminit code in +coreboot), to see what the differences are.
