Chrome OS RMA Shim Bootloader

This is a set of scripts for patching a Chrome OS RMA shim to serve as a bootloader for a standard Linux disto.

Current Development Roadmap:

  • build the image automatically
  • boot to a shell
  • switch_root into an actual rootfs
  • start X11 in the actual rootfs
  • ui improvements in the bootloader
  • load all needed drivers
  • autostart X11
  • host repo for patched systemd packages
  • use debootstrap to install debian

Usage:

  1. Grab a Chrome OS RMA Shim from somewhere. Most of them have already been leaked and aren't too difficult to find.
  2. Download a Chrome OS recovery image for your board.
  3. Clone this repository and cd into it.
  4. Run mkdir -P data/rootfs to make a directory for the rootfs.
  5. Run sudo ./build_rootfs.sh data/rootfs bookworm to build the base rootfs.
  6. Run sudo ./patch_rootfs.sh path_to_shim path_to_reco data/rootfs to build the base rootfs.
  7. Run sudo ./build.sh image.bin path_to_shim data/rootfs. This will generate a disk image at image.bin.
  8. Flash the generated image to a USB drive or SD card.
