        Just for reference, this list is primary used for kernel
development. One marvelous resource I'd suggest is the #kernelnewbies
channel on ; some very knowledgeable people hang out
there and are very willing to answer questions.

        Certainly. It's generally possible to install newer or older
kernels on your system. At boot time, you can pick which kernel to use at
the LILO prompt ("man lilo.conf" for more info).

buildkernel 2.2.10

        The buildkernel script will download the source (up to an hour on
a modem line) and walk you through the rest of the build process. The
entire build can take 3 or 4 hours on a slower system, but you can do
other things while it's going. Buildkernel will beep when it needs

see why buildkernel is doing something.

buildkernel 2.2.15

        You're quite welcome. Feel free to use the #kernelnewbies channel
for kernel questions or contact me privately for buildkernel questions.
