as expected, but when i run on a real machine i either get nothing at all(black screen) on an old laptop of mine, or only the first line, so

on an old pc of mine, it doesn't seem that it continues past there and my kernel starts, i tried writing simple kernels that just shut down the PC or send some data over the serial header on the motherboard but nothing ever worked, both machines are UEFI capable and UEFI was used during all of my tests. On the PC neither UEFI nor Legacy boot work, both get the same result, the laptop isn't legacy capable.
