Recompile kernel without SMP

[Paul Grinberg]

Bill,

Yep, checked....."nosmp" does indeed disable SMP, but that does not help
me.

I need non SMP kernel in order to build kernel module for VPN Client to
work.

Best,
Paul

You can set maxcpu=1 as well, but it will still be an SMP kernel, with
the 
assorted logic which keeps processors from stepping on each other. It
will make 
a small (essentially meaningless) performance improvement on a
uniprocessor 
machine, to quote myself "measurable but not meaningful" in magnitude.

This was important when we ran on 386-16 CPUs with 8MB RAM, it means
essentially 
nothing now, other than he should be able to do it.

Stupid question #1: you did look in grub.conf to see that you are
booting the 
right kernel? That your new kernel is even in grub.conf?
