bootroms: Add ROM kernel image for booting from floppy The kernel is sitting in ROM but includes the boot_1773_6ms module for loading the bootfile from a floppy. For bootstrapping NitrOS-9 using the normal floppy disks (images), without any disk BASIC installed. Can be useful for emulator bundling and NitrOS-9 purists.
