Run Slopos

Overview

Run the slopos bootloader in QEMU headless mode and verify the text harness output.

Workflow

  1. Build the image
  • Run make from the repo root.
  • Ensure build/os.img is created.
  1. Run headless and capture output
  • Run make run.
  • Expect the harness to print SLOPOS BOOT, Text Harness, and All tests passed.
  • To quit headless QEMU, press Ctrl-A then X.
  1. Troubleshoot
  • If QEMU fails with GTK/display errors, ensure the run command uses -nographic -serial stdio -monitor none.
  • If QEMU reports a write lock on build/os.img, find and stop the existing QEMU process.
  • If output is missing, rebuild with make clean && make and re-run.

Quick checks

  • Confirm nasm and qemu-system-x86 are installed on Ubuntu.
  • Confirm the boot sector signature 0xAA55 exists in the last two bytes of build/bootloader.bin.
