new kernel not installing

[Tom <tjm1@thorn.net>]

I am trying to upgrade from 2.0.36 to 2.1.125.  After configuring with
"make xconfig"  I run "make install". At the end I run lilo.  Everything
seems fine, but when I reboot I am still in 2.0.36.  I tried some
variations.  I ran "make dep", and saw no error messages. I tried
compiling a 486 kernel as well as pentium. My board  is a AMD 586 133. 
The only unusual thing is this.  Prior to installing the 2.1.125 package
I had accidently deleted everything in /usr/src.  I untared the source
there and created /usr/src/linux as a symbolic link to
/usr/src/kernel-source-2.1.124.  But I am not having trouble compiling
so I don't think this is a problem.   I am not sure how to track down
what the problem is.  Any advice or suggestions are appreciated. 
Thanks
