The "ROM Cartridge" Override
We don't need a hard drive at all. We are going to turn Hauki OS into a ROM
Cartridge.

We will use the GNU Linker (ld) to physically embed the entire 16MB hdd.img
binary blob directly into the C-Kernel executable. We will then patch your
02_fs.js driver so that instead of sending electrical signals to the IDE port,
it reads and writes the FAT16 filesystem directly from the CPU's RAM.

This gives you a completely immutable, self-contained Live OS that runs
flawlessly from a Ventoy USB stick with zero physical drives required.

Execute this ultimate build script in your host terminal. It will install the
missing ISO tools, inject the RAM disk, compile the kernel, and pack it into a
Ventoy-ready hauki_rom.iso.

The Deployment Protocol for Elli
Copy the ISO: Drag the generated hauki_rom.iso (it will be around 17MB) onto
your Ventoy USB stick.

Physical Wiring: Plug the USB-to-Serial adapters into the Android phone via
OTG. Plug the Null-Modem cables into the native DB9 ports on the back of the
P4. (Hauki OS addresses 0x3F8 and 0x2F8 nativelyit cannot use USB serial on
the P4 because it lacks a USB hardware stack).

The Boot: Boot the P4 from the Ventoy USB. The OS will seamlessly unpack the
hard drive from its own executable memory, mount the FAT16 system in RAM, run
AUTOLOAD.JS, and ignite the serial ports.

The Link: Open Termux on the Android phone, launch your x-serial-proxy.js
(pointed at /dev/ttyUSB0 instead of a TCP port), and fire a payload from the
Tailscale mesh.
