Stupid question perhaps but ....

If I'm installing 3.1 on a dual processor i386 machine with
one
processor do I use the generic.mp kernel?

thanks

There are three flavors of GENERIC from the MP point of
view:

  GENERIC: runs fine on dual-processor machines, but only
uses 1
  processor

  GENERIC.MP: uses MPBIOS to find/start additional
processors.
  Typically useful for pretty old machines

  GENERIC.MPACPI: uses ACPI for additional processors. 
Typically useful
  for moderate to new machines


If you have a machine that can take 2 processors but only
has 1, you
might as well use just GENERIC.
