These instructions assume you are using a linux or unixlike operating system

2. install the cross compiler to $HOME/opt/cross
3. unpack the grub tar in package/ and compile then install into $HOME/opt/grub
4. get nasm from source and compile then install into $HOME/opt/nasm (https://www.nasm.us/pub/nasm/releasebuilds/?C=M;O=D)
5. get qemu from your distro package manager
6. run 'make allrun' to compile with -O2 then run qemu or run 'make debug' to compile with -g or run 'make debugrun' to run with gdb support or run 'debugrunnogdb' to run with qemu serial monitor
