Prerequisites

• A cross-compiler toolchain compatible with the target architecture (x86_64).
• mkisofs for generating ISO images.
• QEMU for running the OS.

Building and Running

1. Ensure you have all the prerequisites installed.
2. Execute the make.sh script from the root directory:

$ chmod +x make.sh
$ ./make.sh

This will compile the source files, generate an ISO image, and run the OS in QEMU.
