APIC = Advanced Programmable Interrupt Controller.  There are local apics 
and IO-apics, but I'm not sure what the difference is.  Basically the APIC 
handles interrupts for the system taking some load off of the CPU.

IO-APICs are required for SMP, but can also be used in single processor 
systems.  There are apparently a wide variety of problems that can be 
resolved by either enabling or disabling the APIC due to problems with 
various motherboards.
