+# The simplest possible program: just an infinite loop.

+# To convert to a disk image, first prepare a realistically sized disk image:
+#   dd if=/dev/zero of=disk.img count=20160  # 512-byte sectors, so 10MB
+# Load the program on the disk image:
+#   cat baremetal/boot.hex baremetal/ex1.hex  |./bootstrap run apps/hex  > a.bin
+#   dd if=a.bin of=disk.img conv=notrunc
+# To run:
+#   qemu-system-i386 disk.img
+# Or:
+#   bochs -f baremetal/boot.bochsrc  # boot.bochsrc loads disk.img

+# main:  (address 0x9400)
