If you don't get it working, may I suggest you attend the meeting on Feb 14,
when we will be covering DHCP & Cable Modems?

My suggestion is to make the LAN eth0 and then bring up eth1 for the cable
modem. The default settings will configure eth0 properly for the LAN, and
then you only have to worry about configuring eth1

IIRC, 2.2.x kernels will see the RAM without help, whereas you will have to
tell lilo append "mem=96M".  From the BootPrompt-HOWTO:


  ``The kernel will accept any `mem=xx' parameter you give it, and if it
  turns out that you lied to it, it will crash horribly sooner or later.
  The parameter indicates the highest addressable RAM address, so
  `mem=0x1000000' means you have 16MB of memory, for example.  For a
  96MB machine this would be `mem=0x6000000'.  If you tell Linux that it
  has more memory than it actually does have, bad things will happen:
  maybe not at once, but surely eventually.''

  Note that the argument does not have to be in hex, and the suffixes
  `k' and `M' (case insensitive) can be used to specify kilobytes and
  Megabytes, respectively. (A `k' will cause a 10 bit shift on your
  value, and a `M' will cause a 20 bit shift.)  A typical example for a
  128MB machine would be "mem=128m".
