The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

Flashing

The flash chip of this laptop is socketed beside the WLAN slot. You can flash the firmware to another chip and replace it. The original flash chip is MX25L6445E.

You can also do an internal flashing with flashrom after you have coreboot installed and IFD unlocked.
