Sorry if this is a newbie problem, learning assembly/qemu. I updated the Makefile to work with Ubuntu 

.PHONY: qemu
qemu: out/main out/startup.nsh OVMF_CODE.fd OVMF_VARS.fd

At least I think I updated it propery, I updated the path for OVMF. However the os/uefi include I'm not sure where that is supposed to be coming from?

 ls /usr/share/OVMF/
OVMF_CODE.fd  OVMF_CODE.ms.fd@  OVMF_CODE.secboot.fd  OVMF_VARS.fd  OVMF_VARS.ms.fd  OVMF_VARS.snakeoil.fd

Oops, looks like I broke something after shuffling some files around. This should be fixed in the last commit. Try again, and let me know if it still doesn't work! :)

In case you're curious, the issue was just that main.asm included a file called os/uefi.asm (which contains some subroutines for calling into UEFI), but that file was since moved to src/uefi.asm. (In earlier versions, I also had a Linux backend in os/linux.asm, but I removed that in c6c2c19 so I could write some UEFI subroutines in Forth instead of needing to write everything directly in assembly.)

Thanks for letting me know about this!
