+# scripts/boot-image.sh — boot rs-dos full chain disk image in QEMU
+#
+# Builds the image first if needed, then boots with UEFI firmware through
+# the real boot chain: firmware → rsboot → rsnix kernel.
+#
+# Usage:
+#   ./scripts/boot-image.sh [--gui] [--debug] [--mem 512M] [--smp 2]
+#
+# Keybindings:
+#   Ctrl-A X   — quit
+#   Ctrl-A C   — QEMU monitor
+#
+# Environment:
+#   OVMF    path to OVMF firmware (default: /usr/share/edk2/x64/OVMF.4m.fd)
+#   MEM     memory size (default: 256M)
+#   SMP     CPU count (default: 1)
