I'm writing an operating system to learn more about OS development

So far I've been walking through these resources:

http://www.cs.bham.ac.uk/%7Eexr/lectures/opsys/10_11/lectures/os-dev.pdf
https://github.com/cfenollosa/os-tutorial

Compiling so far:

gcc -m32 -ffreestanding -c kernel.c -o kernel.o
gcc -m32 -ffreestanding -c include/port.c -o port.o
gcc -m32 -ffreestanding -c include/screen.c -o screen.o

nasm boot_sect.asm -f bin -o boot_sect.bin
nasm include/kernel_entry.asm -f elf -o kernel_entry.o

ld -m elf_i386 -s -o kernel.bin -Ttext 0x1000 kernel_entry.o kernel.o port.o screen.o --oformat binary

cat boot_sect.bin kernel.bin > os-image.bin
