How to update libreboot (if you are already running libreboot or coreboot)

+ +

+ On all current targets, updating libreboot can be accomplished without disassembly and, + therefore, without having to externally re-flash using any dedicated hardware. In other words, + you can do everything entirely in software, directly from the OS that is running on your libreboot + system. +

Look at the list of ROM images to see which image is compatible with your device.

- X60/T60 users with Lenovo BIOS should refer to #flashrom_lenovobios instead. - Similary, MacBook2,1 users running Apple EFI should refer to #flashrom_macbook21. -

These machines contain the hard coded - MAC address for the onboard ethernet chipset, directly inside the SPI flash; - ich9gen shows how to change it (the default - libreboot ROM images for these machines contain a generic MAC address). -

-

- X200/R400/T400/T500 users should also note, that it is possible for the user to write-protect whole regions - of the SPI flash by using a modified descriptor. Locked regions must be flashed externally; - see x200_external.html, r400_external.html, - t400_external.html or t500_external.html. - Libreboot unlocks all regions, by default. -

Are you currently running libreboot (or coreboot)?

+ +

+ X60/T60 users should be fine with this guide. If you write-protected the flash chip, please refer to + x60_unbrick.html, x60tablet_unbrick.html + or t60_unbrick.html. This probably does not apply to you. Most people + do not write-protect the flash chip, so you probably didn't either. +

+

+ Similarly, it is possible to write-protect the flash chip in coreboot or libreboot on GM45 laptops + (X200/R400/T400/T500). If you did this, then you will need to use the links above for flashing, + treating your laptop as though it currently has the proprietary firmware (because write-protected SPI flash + requires external re-flashing, as is also the case when running the proprietary firmware). +

+ +

+ If you did not write-protect the flash chip, or it came to you without any write-protection + (libreboot does not write-protect the flash chip by default, so this probably applies to you), + read on! +

MAC address on GM45 (X200/R400/T400/T500)

- You should see "Verifying flash... VERIFIED." written at the end of the flashrom output. Shut down - after you see this, and then boot up again after a few seconds. + Users of the X200/R400/T400/T500 take note: The MAC address for the onboard ethernet chipset + is located inside the flash chip. Libreboot ROM images for these laptops contain a generic MAC + address by default (00:F5:F0:40:71:FE), but this is not what you want. + Make sure to change the MAC address inside the ROM image, before flashing it. + The instructions on ../hcl/gm45_remove_me.html#ich9gen + show how to do this.

-
+

+ It is important that you change the default MAC address, before flashing. It will be printed on a sticker + at the bottom of the laptop, or it will be printed on a sticker next to or underneath the RAM. Alternatively, + and assuming that your current firmware has the correct MAC address in it, you can get it from your OS. +

+ +

All good?

+ +

Excellent! Moving on...

+ +

+ Download the libreboot_util.tar.xz archive, and extract it. Inside, you will find + a directory called flashrom. This contains statically compiled executable files of + the flashrom utility, which you will use to re-flash your libreboot system. +

+ +

+ Simply use cd on your terminal, to switch to the libreboot_util directory. Inside, + there is a script called flash, which will detect what CPU architecture you have + (e.g. i686, x86_64) and use the appropriate executable. It is also possible for you to + build these executables from the libreboot source code archives. +
