Kernel-Compile-mini-HowTo "Trust this, and live, with a new kernel." (Kent)
ncftp> open                                                        
ncftp> cd /pub/Linux/kernel/src/v1.3       </v1.3 ? As of this writing.>
ncftp> ls LATEST*    
ncftp> bin     <Set to binary mode.>      
ncftp> get linux-1.3.85.tar.gz          
ncftp> quit

?/# mv linux-1.3.85.tar.gz /usr/src
?/# cd /usr/src
/usr/src# rm -rf linux                   <Remove old kernel.>
        # tar xzvf linux-1.3.85.tar.gz   <Unpack new kernel.>
        # cd /usr/include
/usr/include# ln -s /usr/src/linux/include/linux linux   <Create new links.>
            # ln -s /usr/src/linux/include/asm-i386 asm  
            # cd /usr/src/linux

Try and read /usr/src/linux/Documentation/, this will
explain, the various options you have, in configuring the kernel.

/usr/src/linux# make config
              # make dep  
              # make clean
              # make zlilo
              # make modules           <To install any modules?>
              # make modules_install

If the kernel compiled, you'll have, /vmlinuz /vmlinuz.old.
If your useing lilo to boot linux, everything is fine as is,
but if your booting from a floppy, do this.

/# fdformat /dev/fd0H1440      <Format a floppy.>
/# cp vmlinuz /dev/fd0H1440    <Copy kernel to floppy.>

Boot the new kernel, then /# rm vmlinuz.old
You don't need all of the kernel source, after it's compiled,
you just need /usr/src/linux/include, you'll need the include files,
to compile anything.

~/# mv /usr/src/linux/include /usr/src        <Steps, to removing
~/# rm -rf /usr/src/linux                      kernel source, minus
~/# mkdir /usr/src/linux                       the include files.>
~/# mv /usr/src/include /usr/src/linux

To remove just the (o)bject files, that were created, when you compiled the
kernel, do this...

~/usr/src/linux# find . -name "*.o" | xargs rm

I would keep the kernel source, and just remove the (o) files, unless I
was short on space, don,t forget # rm linux-1.3.85.tar.gz.>
