Description

Hi!
First off, I wanted to thank the creator and the contributors of this package for all the great work.

Now, onto the issue:
I have been using the bootloader to run a small kernel I'm writing and I have noticed that while I can boot when the built image is attached as a hard drive to QEMU, I am not able to boot when it's attached as a CD-ROM.
I have dug deeper and from what I've read it is because CD-ROMs have a completely separate booting system called El Torito.

As such, I would like to know if there would be a possibility of adding El Torito support and add it so we could build the images directly for booting from a CD?

Research direction

Start by examining how the bootloader currently builds images and how those images are attached to QEMU as hard drives. Research the El Torito boot process and define the required image-building changes; done means the package can produce an image that boots when attached to QEMU as a CD-ROM.
