UI plan (meets assignment requirement)

The assignment requires a UI (GUI, CLI, or web-based) appropriate for the project. For an OS kernel prototype, the fastest and most reliable UI is an interactive CLI.

Current UI (implemented)

Serial CLI (interactive)

  • Runs over COM1 and works with QEMU -serial stdio.
  • Gives an interactive prompt (mk>) so the team can demonstrate features quickly.

Commands (MVP)

  • help — list commands
  • clear — clear VGA text screen
  • echo <text> — print text
  • about — short info
  • halt — halt CPU

Why serial?

  • No keyboard driver required.
  • Works immediately in QEMU and is easy to record for demos.

Next UI iterations (optional)

VGA “dashboard” (non-interactive)

  • Reserve top few lines for system status (services, IPC stats).
  • Keep scroll area for logs.

Keyboard input

  • Add PS/2 keyboard driver and move CLI input to VGA.

Graphical UI

  • VESA linear framebuffer (or Bochs/QEMU framebuffer) + bitmap font.
  • Out of scope for a 7-day prototype unless the rest is already stable.

Demo guidance

Run make run and type commands into the QEMU serial console. Capture the serial output for your submission screenshots/video.
