SMP Problem on IBM x330 Server

[Tom Everett]

ok, two problems.  I don't remember that I had the option to explicitly 
install an SMP kernl, and looking back here 
(http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/install.html) 
, I don't see that sysinstall gave me that option.  Additionally, I have 
the kernel source and I see that in GENERIC, SMP is enabled.  Am I 
missing something?
