How to use Filo as a payload ?

That's it.

I hacked together a new timer.c based on freebios/src/pc80/udelay_timer2.c

You may want to offer it as an alternative, but then again, maybe not.

I can now boot linux using filo !

Thanks for all your help.

  Maybe RDTSC causes invalid opcode exception, and since there is no
  exception handler, the CPU resets.
  
  filo/i386/timer.c must be re-written to support pre-Pentium CPUs.
