README.md

rOSka

Probably useless hobby OS project
Targets 32bit legacy systems with graphical framebuffer
Boots with multiboot compatible bootloader, such as GRUB
Assembles with FASM
We'll probably use ext2 filesystem

GRUB disk creation

Format disk. Create ext2 partition
Create directory mnt and mount your partition to it
```
    mkdir mnt
    sudo mount /dev/sdX mnt
```
Intall grub using sudo grub-install --target=i386-pc --removable --boot-dir=mnt/boot /dev/sdX

Create config

    menuentry "rOSka" {
        multiboot /boot/roska.bin
        boot
    }

Copy assembled kernel to mnt/boot/roska.bin

Oh yeah heres a montrosity I currently use. fasm roska.fasm && sudo mount /dev/sdd1 mnt/ && sudo cp roska.bin mnt/boot/roska.bin && sudo umount /dev/sdd1 && sudo sync && sudo qemu-system-i386 /dev/sdd
