make run

Flash a usb drive

Be careful with this command, it will format your usb drive.

dd if=obj/tetanos.iso of=/dev/diskX && sync

Note for OSX dev

GNU ld doesn't work on OSX, so we cross compile it for elf target

mkdir -p ~/src/ && cd ~/src/
wget https://ftp.gnu.org/gnu/binutils/binutils-2.24.tar.gz
tar -xvzf binutils-2.24.tar.gz && cd binutils-2.24
./configure --target=x86_64-elf --prefix="$HOME/opt/cross" \
	--disable-nls --disable-werror \
	--disable-gdb --disable-libdecnumber --disable-readline --disable-sim
make
make install

then set LINKER=~/cross/bin/x86_64-elf-ld when calling make (required for kernel target)

make kernel LINKER=~/cross/bin/x86_64-elf-ld
