Hi,

I have a Pixelbook Go (codename: Atlas), how to get/compile Tianocore EDK2 payload for RW_LEGACY firmware?

hard way:

  • clone coreboot repo
  • build coreboot for qemu M35 using uefipayload_rwl edk2 branch
  • read existing RW_LEGACY firmware
  • remove contents using cbfstool
  • add edk2 payload using cbfstool
  • flash back to device

easy way:

  • ask me to add support to the script

Adding support for this in the script would be awesome. Thanks in advance!

added. completely untested, so LMK how it goes. You should get a prompt for selection between SeaBIOS and edk2 when installing RW_LEGACY on Altas (or any KBL device)

Installed this and was able to boot into Ventoy in UEFI mode, thanks!
