I have just subscribed to this mailinglist, so I do hope you forgive me
if I ask a redundant question about recompiling my Kernel;
Hardware: Dell OptiPlex 755
System is up and running (limping on one core, but hey, I should begin
somewhere :-)
For checking wheter my hardware would fit for SMP Kernel I did a
triton# /usr/sbin/mptable

So far so good K-)

My question is now: would this be oke to compile a new Kernel for my
dual core based processor?
Thanks for sharing,
