Thanks Bill! I'm starting to like freeBSD a lot, I noticed that whenever I 
install anything and it  detects that needs dependencies it downloads them 
automatically and then compiles them and keeps updating !.

I'm running SETI to see if the CPU usage shows both CPU's running at 100% 
but the "top" command doesn't say if it's 2 or 1 cpu running. and then I 
read on the web the following :

Operating Systems
Some operating systems use SMP better than others. For instance, recent Mac 
OS X statistics have shown better than a 100% speed increase with the use of 
a second processor on some systems. Windows 9x systems have none while 
Windows NT 4.0 had poor SMP capabilities (Windows 2000 and XP have 
improved). UNIX server OSs such as Solaris and IRIX have had multi-processor 
support for a long time and are highly efficient. Linux SMP support has 
always existed but has improved with each version of the Kernel as it 
continues to approach a greater server-readiness. FreeBSD has SMP support 
since version 5. OpenBSD has SMP support since 3.6. NetBSD currently 
unknown. Keep in mind it might not be supported (well) on all architectures.

So freeBSD 4.1 doesn't run SMP right ?
