:Is it possible to build & run an SMP kernel on a DP board with only one CPU
:installed? I know this is kind of a silly thing to do but I was just
:wondering if it is possible.
:
:I tried it on my BP6, but got a "panic: NO BSP found!" or something like
:that on boot. If this is indeed possible I can give it another go, and
:post my mptable, dmesg, and kernel conf.

It should work just fine, simply compile and run a UP kernel on it
(or perhaps an SMP kernel with NCPU set to 1). A number of machines
at a company I consult for run UP kernels on SMP boxes with only one cpu
populated.
