Have you ever wondered how operating systems are made? Are you disappointed by the fact that college doesn’t teach you how to make an operating system from scratch?
In this HaP Day on the 16th July we’ve seen how to build an OS from bootloader to shell!
For this HaP Day a GNU/Linux laptop with qemu (emulator), nasm (assembler) and gef (debugger) installed was required. Ah! And willingness to learn, obviously!
Started at 9:42am in Laboratory 0.08 (ground floor), Department of Computer Science – Faculty of Sciences of the University of Porto, 4169-007, Rua do Campo Alegre 1021, Porto
