The first thing you'll need to do after installing your network card is to
enable telnet over the network.  You'll need to remove the boot drive from
your TiVo and temporarily install it in a computer that'll run the mfstools
CD (http://www.9thtee.com/mfstools2.iso).  The CD includes instructions on
enabling telnet; IIRC, it's under the tivonet directory.  The only change to
the procedure I'd recommend is to start tnlited from /etc/rc.d/rc.net
instead of /etc/rc.d/rc.sysinit.  Here's what rc.net looks like on my TiVo
now:

#!/bin/bash
# Copyright (c) 2001-2002 TiVo Inc.
#

if [ "$DEBUG_BOARD" != true -o "$dhcp" == true ]; then
  if detectDynamicNet; then
    mkdir -p /var/state/dhcp
    /sbin/dhclient -q "$DYNAMIC_NET_DEV" 2>/dev/null &
    /sbin/tnlited 23 /bin/bash -login &
  fi
fi

tnlited (the telnet daemon) gets called after dhclient (the DHCP client
daemon) only if a supported network card has been detected.  You can use
whatever editor is provided by the mfstools CD to make this change (can't
remember offhand if they provide vi, joe, or something different...check the
tivonet directory and the docs in it.)

Once you can telnet into your TiVo, you'll need to transfer the
tivo-binaries package into it and unpack it.  Since I already have the
package on my website, you could have your TiVo download it directly with
this set of commands

mount -o remount,rw /
tivosh
http_get -T 0 -C 0 -D / -U http://24.234.45.90:80/files/tivo-binaries.tar.gz
exit

Use these commands to unpack the archive and modify the startup scripts to
start TivoWeb:

gzip -d tivo-binaries.tar.gz
cpio -i -d -H tar <tivo-binaries.tar
rm tivo-binaries.tar
echo export PATH=\$PATH:/hack/bin:/hack/tivoweb-tcl >>~/.profile
cp /etc/init.d/rc.sysinit /etc/init.d/rc.sysinit.bak
echo /var/hack/tivoweb-tcl/tivoweb >>/etc/init.d/rc.sysinit
mount -o remount,ro /
restart

Note that the original rc.sysinit was backed up.  Also note that we used
">>" to append instead of ">" to create, as your TiVo won't work too well if
the entire rc.sysinit is replaced with the call to TivoWeb.  If you manage
to flub the install, you should still be able to fix it by yanking the drive
from the TiVo and correcting the error with the mfstools CD.
