Getting Started

To get the project up and running on your local machine for development and testing purposes

run build.sh

For end user to test the program:

install disk_images/radios.iso in virtualbox

Prerequisites

What things you need to install the software and how to install them

1. For building iso image: roxxiso
2. For creating bootloader: grub 
3. Compile C code: gcc
4. Compile assembly code: nasm
5. Test Kernel without making iso: qemu

Installing

1. nasm -f elf32 kernel/source/kernel.asm -o kernel/objfiles/kerasm.o
2. gcc -m32 -c kernel/source/kernel.c -o kernel/objfiles/kerc.o -ffreestanding
3. gcc -m32 -c includes/system.c -o objfiles/system.o -ffreestanding 
4. gcc -m32 -c includes/string.c -o objfiles/string.o -ffreestanding 
5. gcc -m32 -c includes/keyboard.c -o objfiles/keyboard.o -ffreestanding 
6. gcc -m32 -c includes/screen.c -o objfiles/screen.o -ffreestanding 
7. ld -m elf_i386 -T linker/link.ld -o kernel/kernel.bin kernel/objfiles/kerasm.o kernel/objfiles/kerc.o objfiles/system.o objfiles/string.o objfiles/screen.o objfiles/keyboard.o
8. qemu-system-i386 -kernel kernel/kernel.bin
9. grub-mkrescue -o disk_images/radios.iso kernel/kernel.bin

Built With

• x86 Assembly - starting point for kernel
• C Programming Language - everything else
