Toast, Take 2

[Bonez]

Having compiled a downloaded source for 2.4.18, I proceeded to update my
bzImage and System.map files in /boot.

Since I am using GRUB as my bootloader, I went in and created a new enter
for the new 2.4.18 kernel, to try booting with it.

Now, where I had sound, networking to the internet, email, web browsing
etc., when I boot up to my original 2.4.2 configuration, the sound, access
to the net, is all gone, plus I get multiple failure notices as the various
modules and daemons load at boot time.

How can I get things back to the way they were before, so that I can boot up
and continue working on my upgrade?

In my effort to upgrade I followed the listing found at www.linuxnewbie.org,
under configuration and compilation of new kernel.
