Thanks to Colin for pointing me on the way to a solution. To get the
system configured correctly for SMP, you have to have the APIC enabled
by selecting an OS type that Compaq recognizes as SMP capable. Linux
and WinNT/2000 are valid choices. My setup version did not have Linux
as a choice, so I used WinNT/2000 and all seems well.
