# 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

# qemu-system-i386 disk.img
