No, you're not there yet: 'make dep' updates just the dependencies inside the
source tree. 

You have to 'make bzImage' to actually create a kernel, then 'make modules' to
recompile the modules - aka runtime insertable/removable drivers.

At this point, everything is ready, but yet to be installed: your new kernel is
placed at

 _kernel_source_top_/linux/arch/i386/boot/bzImage

so copy it into /boot, let's say to

 /boot/vmlinuz-2.4._stick_your_version_here_-very-large-mem

and then install the new modules with 'make modules_install'. If your system
requires any of these new modules in order to boot, you could also have to 
update your initrd image at

 /boot/initrd-...

Chances are you don't need this step, but if you do and skip it, your system
won't boot with the new kernel.

The final step is to configure your boot loader - which still doesn't know
anything about your new toy - to look for it. If you use the default install of
grub, the config file is /boot/grub/grub.conf; should you be using LILO, go
for /etc/lilo.conf (and remember to rerun LILO after you change it!).

But please, before doing anything, READ CAREFULLY _AT_LEAST_ THESE DOCS:
- _kernel_source_/README
- _kernel_source_/Documentation/initrd.txt
- 'info grub' or 'man lilo.conf'

Hope this helps to clear up your way a little bit!

OK, so you're a Ph.D, great... just don't touch anything.
