X60/X60S/X60T/T60: How to flash the ROMs onto your machine (if running Lenovo BIOS firmware).

How to install or update libreboot (if running libreboot or coreboot)

-

- Hover over the next paragraph to make it black. + If you are using libreboot_src or git, then make sure that you built the sources first (see ../git/index.html#build).

-

- Following this guide means simply flashing a libreboot ROM. This guide will not (directly) teach you how to make a backup (dump) of the original Lenovo BIOS - because to do so would be to explicitly endorse proprietary software. However, for the purposes of reverse engineering it can be useful - to have a backup. Each copy of the original Lenovo BIOS is tied to the specific machine that it came from; it will not run - on any other machine, even if it's the same type of machine as yours. What this means is that, effectively, you can back it up now (so that you can - re-flash it later if you want to run the original Lenovo BIOS again) or lose it forever. The X60/T60 installation - guide on the coreboot wiki will show you how to do this: - http://www.coreboot.org/Board:lenovo/x60/Installation.
- Do not make this decision lightly! This is your last and only chance. +

+ +

+ These instructions work for most targets, provided that they are already running libreboot or coreboot. +

+

+ 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. +

+

+ + ThinkPad T60 and X60 Tablet users: be sure to read ../hcl/index.html#supported_t60_list + or ../hcl/index.html#supported_t60_list. + +

+

+ X200/R400 users running Lenovo BIOS should refer to x200_external.html + or r400_external.html. 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 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 or r400_external.html. + Libreboot unlocks all regions, by default. +

+
+

+ How to update the flash chip contents:
+ $ sudo ./flash update yourrom.rom

- +
+

- The following is for the libreboot image and *not* the factory bios dump: + Ocassionally, coreboot changes the name of a given board. If flashrom complains about a board mismatch, but + you are sure that you chose the correct ROM image, then run this alternative command:
+ $ sudo ./flash forceupdate yourrom.rom

+
+ +
+

- Check the last two 64K regions in your ROM file (libreboot.rom in this example):
- $ dd if=libreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s libreboot.rom) - 0x10000] count=64k
- $ dd if=libreboot.rom of=lower64k.bin bs=1 skip=$[$(stat -c %s libreboot.rom) - 0x20000] count=64k
- $ sha512sum lower64k.bin top64k.bin
- Make *sure* that they match before you continue. The ROMs included pre-compiled in libreboot should already match. - If they don't match, then do this (based on those instructions from coreboot wiki):
- $ dd if=top64k.bin of=libreboot.rom bs=1 seek=$[$(stat -c %s libreboot.rom) - 0x20000] count=64k conv=notrunc
- After this, the ROM will be safe to flash. Explanation is provided in ../git/index.html#build_bucts. + 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.

- - If you have an X200 or R400 with libreboot or coreboot already running, note that - the Gbe in the boot flash contains your MAC address.

See - ich9gen for details. - - Another important note about the X200/R400: even if you do already have libreboot or coreboot, - it is possible for the user to write-protect regions in the flash chip, by modifying - the flash descriptor. If you have locked regions, you will need an external flasher - (see x200_external.html or x200_external.html) - to re-flash those regions.
