Project Info:
SH1MKEX is a universal bootloader for Chromebooks. It uses an RMA shim to initialize the hardware, then provides a menu to select and boot any Linux distribution via kexec. Unlike original shimboot, you are not locked to the ChromeOS kernel.

The Kexec Advantage:
Traditional shimboot forces you to use the ChromeOS kernel, which breaks many systemd features. SH1MKEX solves this by using "kexec" to jump into a modern Linux kernel (like Arch or Ubuntu) stored on your USB. This means:
- No more patched systemd.
- Faster boot times.
- Better hardware support via modern kernels.

Build Instructions:
SH1MKEX does not provide prebuilt images. You must build your own:
1. Clone: https://github.com/flowdev-yee/SH1MKEX
2. Run: `sudo ./build_complete.sh [board_name]`
3. The script will automatically inject kexec-tools into your loader.

Booting OSs:
1. Flash your SH1MKEX .bin to a USB.
2. Use GParted to add new EXT4 partitions for your other OSs (Arch, Alpine, etc.).
3. Plug into your Chromebook, enter recovery mode, and select your OS from the SH1MKEX menu.
