Here are a couple of ways.  I'm not sure which is easiest:
1. Try it in a simulator (SimNOW or Qemu)
2. Print out the memory at the entry point to see if it looks like good code
3. Move FILO to an address that isn't the same as the kernel (they
both use 0x100000)
4. Use FILO to load some other payload

Sorry it's pretty generic.  Any FILO experts care to weigh in?

Good luck,
Myles
