Hello everyone, it seems that I haven't posted on this topic for a while. In the last months, I have been porting ToroOS to fpc-3.2.0 (see
https://github.com/torokernel/ToroOS). I have some progress that I would like to share. In the
https://youtu.be/DyqEqPeUYB8, you can see ToroOS booting up in QEMU/KVM. I just show the shell and the ls command. I am porting the fpc rtl named embedded32 so you can build applications for Toro from fpc. ToroOS is a 32 bits general-purpose OS for x86 that supports multitasking and paging. Also, it has a VFS and is POSIX so porting Linux app should be easy.
