Building new kernel help

[Darryl Hoar]

I was following the handbook (/usr/share/doc).
There are two methods in 5.1-release of building
a kernel.

Method 1.  
    The /usr/sbin/config MYKERNEL
    cd ../compile/MYKERNEL
    make depend
    make
    make install

Method 2.  
    cd /usr/src
    make buildkernel KERNCONF=MYKERNEL
    make installkernel KERNCONF=MYKERNEL

the handbook recommended method 1 if you had not
cvsup.  So, I did method 1.

The thing that's throwing me is in 5.1-release, it
brings up a character menu of choices when booting
(complete with ascii art of the mascot).  What option
do I choose so I can do:
boot kernel.old ?

thanks,
Darrl
