Gheorghe, thank you

I got the kernel built, but only after I enabled SMP.
As this is US-IIIi UP box, it would make more sense
to disable this option, but then I don't know what
effect it would cause. In other words, is there
a negative effect of running SMP kernel on a UP
machine?

The full kernel config file is below.

many thanks
anton
