I'm cheating a little bit by booting to single-user mode, mostly just to test the basics (e.g. xclock, xterm) before letting the userspace try and run gdm and its own X server.
I'm not sure I understand what is going on. Is your OS running Xnest which redirects the X output to the host OS? Did you port stuff like an init system, ifup/down and the ALSA user-space to your OS? That is quite a remarkable achievement! Did you have to implement many Linux specific system calls/interfaces in order to be able to do that? :D

i wasn't into x86 too long, don't even know if this possible for a 16-bit register to hold a 24-bit value.) btw, it definitely points to some code near the current IP.
ANT - NT-like OS for x64 and arm64.
efify - UEFI for a couple of boards (mips and arm). suspended due to lost of all the target park boards (russians destroyed our town).

Update: All the values are 32 bit, 16 bit values are properly translated.

I meant SS. Your printing code prints something else instead of SS.)

FYI, "cat" should run without arguments, if you are implementing POSIX. It should cat from stdin in that case, not throw an error and exit.
