@ -201,19 +201,11 @@ How to erase and rewrite the chip contents:
sudo flashrom -p internal:laptop=force_I_want_a_brick,boardmismatch=force -w libreboot.rom
If flashing GM45 laptops such as Thinkpad X200/T400/T500/R400/W500/R500, you
might consider doing this instead:
sudo flashrom -p internal:laptop=force_I_want_a_brick,boardmismatch=force --ifd -i bios -w libreboot.rom
The `--ifd -i bios` option, when you use a ROM for GM45 machine, will only flash
the BIOS region. On those machines, the boot flash is split into IFD, GbE and
BIOS region. The GbE region contains your MAC address. If you already ran
the `ich9gen` program before, you can use these options to skip flashing over
those sections. Otherwise, without these options in flashrom, you will just
flash the entire chip. If you're flashing the entire chip, make sure that the new
ROM has a MAC address set correctly in the GbE region. To learn more about this,
please read the ich9utils documentation: [/docs/install/ich9utils.html](/docs/install/ich9utils.html)
If you are re-flashing a GM45+ICH9M laptop (e.g. ThinkPad X200/X200S/X200T,
T400, T500, R400, W500 etc - but not R500), you should run the ich9gen utility
to preserve your mac address.
Please read the ich9utils documentation:
[/docs/install/ich9utils.html](/docs/install/ich9utils.html)
NOTE: `force_I_want_a_brick` is not scary. Do not be scared! This merely disables
the safety checks in flashrom. Flashrom and coreboot change a lot, over the years,
