proprietary components status

  • CPU Microcode
  • VGA Option ROM (optional)
  • ME (Management Engine) firmware
  • EC (Embedded Controller): The EC in this laptop is SMSC KBC1126. It needs two blobs in the flash chip. You can move the blob from 0x780000 to another address in the flash chip so that you can have a bigger CBFS size. Read this post for more info.

Building

The source code is at https://review.coreboot.org/#/c/18241/. You can check it out and rebase it on the master branch.

Extract the blobs needed by EC according to this post and use dd to write it to coreboot.rom.

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.
