compile_isogen.sh

Creates a bootable GRUB ISO image containing the Asuro kernel.

Overview

compile_isogen.sh copies the compiled kernel binary into the ISO directory structure and invokes grub-mkrescue to produce a bootable CD-ROM image. The resulting Asuro.iso can be booted in any x86 emulator (QEMU, VirtualBox, etc.) or written to physical media.

Prerequisites

• grub-mkrescue (from GRUB utilities) and xorriso (its backend) must be available.
• bin/kernel.bin must exist (produced by compile_link.sh).
• The iso/boot/ directory must exist and contain a GRUB configuration file (iso/boot/grub/grub.cfg).

Inputs

Source	Description
bin/kernel.bin	The linked kernel binary.
iso/	Pre-existing ISO directory tree with GRUB configuration.

Outputs

File	Description
Asuro.iso	Bootable GRUB rescue ISO image.
iso/boot/asuro.bin	Copy of the kernel binary placed into the ISO tree.

Behavior

1. Copies bin/kernel.bin to iso/boot/asuro.bin.
2. Runs grub-mkrescue -o Asuro.iso iso to generate the bootable ISO from the iso/ directory tree.

Notes

• The GRUB configuration in iso/boot/grub/grub.cfg must reference asuro.bin as the kernel to load.
• The ISO is generated in the project root directory.
