# Deploying to a EFI-compatible system

See [doc/deploy] and [doc/hw/efi] first.

A Dusk media that boots on a AMD64 EFI is a FAT with a EFI/BOOT/BOOTX64.EFI
file in it. This is what the unit at [xcomp/amd64/efi/deploy.fs] does.

Dusk's boot payload directly follows the kernel binary directly in the ".EFI"
executable. Then it uses [drv/efi/blkio] plugged into [fs/fat] to boot further,
until `init.fs` is reached.

## Usage

To use this unit, you will first want to create a new FAT with [fs/fatt], then
copy Dusk's files into that new file. Then, you'll want to create a
EFI/BOOT/BOOTX64.EFI file with the contents generated with "spitefi".

You now have a bootable disk!

## API

spitefi ( stream -- )
  Generates a PE+ executable with a single RWX section named ".text". It's
  content is the result of compiling [xcomp/amd64/efi/kernel.fs] and inlining a
  boot payload next to it. That payload is the minimal code required to get
  [drv/efi/blkio] and [fs/fat] going, so that we can mount the boot disk and
  interpret "init.fs".
