   It's easy to confuse ACPI with APIC, but the twain are quite different    
   things.  Enabling local APICs and I/O APICs is what one wants with an    
   SMP operating system.  (Strictly speaking, if one doesn't have APICs,    
   then one isn't doing *symmetric* multiprocessing, because when using the    
   old PC/AT dual 8259 PICs interrupts are only routed to the "boot"    
   processor.)  Although an SMP operating system should be capable (in most    
   circumstances) of enabling the use of the APICs itself, even if the    
   firmware didn't enable them.

   Actually, it's the MPS table.  Again, don't confuse the twain.  The    
   differences between 1.1 and 1.4 are very probably irrelevant for OS/2 or    
   for your machine.
