Hi :D

When I try my OS on real hardware, BOCHS and Virtual Box, I always receive the 0xE0 code when pressing "special" keys like AltGr and DELETE. But with QEMU, I don't :/
I only receive the part after the 0xE0

Here is the command I use to start QEMU (Windows 10):
Code:
qemu-system-i386 -kernel bin/MemeOS.bin


Is it me doing something wrong or is it a BUG ?

Thanks !

Have you tried doing the exact same thing on Linux?
I remember having some issues (all keyboard related) with Qemu on Windows, whereas on Linux (my development environment) I wasn't having any issues at all.
