# The simplest possible program: just an infinite loop.
# All is well if your computer clears screen and hangs without restarting.
# On an emulator the window may get bigger to accomodate the higher-resolution
# graphics mode.
#
# 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:
# ./translate_subx_baremetal baremetal/ex1.subx # emits a.bin
# apps/hex < baremetal/boot.hex > boot.bin
# cat boot.bin a.bin > disk.bin
# dd if=disk.bin of=disk.img conv=notrunc
# To run:
# qemu-system-i386 disk.img
# Or:
# bochs -f baremetal/boot.bochsrc # boot.bochsrc loads disk.img
