While backing up the proprietary BIOS image might be construed as "endorsing" proprietary software: This BIOS image is unique to every motherboard. It will be impossible to restore the original BIOS once it is lost. Back it up now or you will lose it forever. Do not take this decision lightly.
If you choose to make a backup, click [Expand] on the right and follow the directions.
From the libreboot_bin/ folder, enter the flashrom/ folder.
Run both of these commands to backup the BIOS to factory.bin (don't panic, nothing is being installed):
Wait for the process to finish. Expect to see "critical errors" during flashing, but don't panic; proceed to the next step to check if the flash ran correctly.
The line below is displayed if bucts 1 was enabled successfully.
Updated BUC.TS=1 - 64kb address ranges at 0xFFFE0000 and 0xFFFF0000 are swapped.
If BUC.TS 1 was not enabled, do not continue, do not turn off your laptop. Run the flash script again.
The following "errors" are displayed if flashrom installed Libreboot correctly. The output must be very similar (later versions of flashrom may have minor differences).
If the "errors" do not match, do not continue, do not turn off your laptop. Run the script again. If the output still doesn't match, something is wrong; reinstall the factory.bin image and start over.
Reading old flash chip contents... done.
Erasing and writing flash chip... spi_block_erase_20 failed during command execution at address 0x0
Reading current flash chip contents... done. spi_block_erase_52 failed during command execution at address 0x0
Reading current flash chip contents... done. Transaction error!
spi_block_erase_d8 failed during command execution at address 0x1f0000
Reading current flash chip contents... done. spi_chip_erase_60 failed during command execution
Reading current flash chip contents... done. spi_chip_erase_c7 failed during command execution
Uh oh. Erase/write failed. Checking if anything changed.
Your flash chip is in an unknown state.
If the "errors" closely match the lines above, shut down the laptop (don't restart).
Wait a few seconds, and then boot. Libreboot will start up.
Use the Search for GRUB configuration on local storage option if the normal menu options don't work.
After booting into Linux, proceed to Libreboot Second Flash.
If you boot and you see nothing, try turning up the backlight with Fn+Home. For ThinkPad X60 models, if the backlight resets to zero when turning it up while at max, consult Libreboot's TFT Brightness Guide.
If the laptop turns on, but doesn't boot at all; and there is absolutely no sounds or sign of life, Libreboot might have been flashed incorrectly. It is still possible to return to the Lenovo BIOS by disabling bucts 1. Disassemble the laptop and unplug the CMOS battery for at least 5 seconds. Plug the CMOS back in, reassemble the laptop, and turn it on. The Lenovo BIOS should appear, though it will require you to set the time in BIOS Setup. Boot into Linux, and start over from step 1 immediately.
If the laptop emits three loud beeps when turned on, it has been fully bricked. A hardware BIOS flasher is required to restore it to working order. We recommend a $40 Bus Pirate and $20 8-pin Pomona Clip from eBay.
