   The last time around, M. Piatkowski said APIC, not ACPI.  I pointed out    
   then that xe shouldn't be mixing up xyr initialisms.  Disabling the    
   Advanced Configuration and Power Interface is a very different kettle of    
   fish to disabling any use of Advanced Programmable Interrupt    
   Controllers.  It's actually the latter that M. Piatkowski is doing.   
      
   In an AMIBIOS machine, the setting that M. Piatkowski was talking about    
   earlier is named "ACPI APIC Support" and it deals with APICs.  In    
   AWARD-Phoenix firmwares, the equivalent setting is named "APIC Mode".    
   It almost goes without saying that if one disables the use of APICs    
   entirely, by setting APIC mode to "disabled", then I/O APICs are as a    
   consequence unavailable.  If all local APICs are switched off during    
   POST (as essentially all that this setting has to do), then whatever I/O    
   APICs may do is entirely irrelevant: there is no-one listening to them.
