upgrading from 4.2 to 4.10, succeeded, but still boots 4.2! Help!!!

[Zachary Huang]

OK, my old questions might be too simple and I did not get much help from here. 
My old system was 4.2 and I was trying to upgrade to 4.10.  (hardware:
K2-6 350 MHz with 384 meg and 20 gig)

here is what I managed to do:

1). cvsup to RELENG_4_10
here is the supfile

*default host=ftp5.FreeBSD.org
*default base=/usr
*default prefix=/home/ncvs
*default release=cvs tag=RELENG_4_10
*default delete use-rel-suffix
src-all
ports-all

which seemed to be successful (did not see the final message because
too many spams filling on my screen, but it was going for a good 30
min -- could it have stopped in the middle?)  -- how do I stop the
rejected spams showing on the console? very annoying.

2). then I proceeded to  follow the book:
        make buildworld 
        (config MYKERNEL --this was not in the book)**this should not
mess things up?
        make buildkernel KERNEL=MYkernel
        make installkernel KERNEL=MYkernel
        reboot  (in single user) [1]
        make installworld
        mergemaster
        reboot

no error messages doing all the above steps.

3). I noticed that after reboot the machine was still showing:

FreeBSD 4.2-RELEASE #1: Thu Dec 16 08:53:22 EST 2004

4). So I recompiled the kernel by doing:
 cd /usr/src/sys/i386/conf
 /usr/sbin/config Mykernel
/cd ../../compile/Mykernel
make depend
make
make install

5). after reboot, I still see the same "4.2. RELEASE! 

6). indeed. all the files in /usr/src seems to be the same as before updating...

7). Can someone here tell me what I did wrong?  I was not sure if
cvsup grabbed the right source or not, but usually when I was playing
the tag before, it would give me error messages if the tag was not
correct.

Thanks so much and happy holidays!
