who states "Heavily inspired by palo"
There are five parameters which get encoded into the first 248 bytes of the
System Area: cmdline, bootloader, 32-bit kernel, 64-bit kernel, and ramdisk.
They are all mandatory.
While cmdline is simply a string of at most 127 characters, the other four
point to data files inside the ISO image.
All numbers are recorded big endian.
Boot sector components:
