A friendly neighbourhood operating system with a 32 bit kernel.

Features it has:

1. Multiboot using grub
2. Colorful text mode output ( and a welcome banner :P )
3. Fully functional keyboard drivers
4. Memory protection using Global Descriptor Table
5. Interrupt Descriptor Tables
6. Interrupts handling using ISR
7. Interrupt Requests

Now PulseOS uses dock-cross ( https://github.com/dockcross/dockcross ) for cross-compiler management. Also It has its own NASM subtree that gets compiled beforehand.

A dockcross script is attached but you will need your own dockross script to work.

docker run --rm dockcross/linux-x86 > ./dockcross

To make,

./dockcross bash -c 'make'

There are multiple ways you can go about running the OS. The simplest is :

qemu-system-i386 -kernel ./bin/myos.bin

If you are on linux, and you have grub-mkrescue installed, then you can make a multi-booting ISO using it.

cp ./bin/myos.bin ./iso/boot/
grub-mkrescue -o myos.iso ./iso

And then run it using

qemu-system-i386  -cdrom ./myos.iso
