About the internal workings, yes.  But I hope to have covered most of
the user side of things in boot(8), ip(4), and the various manual pages
they refer to.

For the NE2000 the <memaddr> parameter is ignored, so it can be omitted.
Anyway, if you don't set DPETH0 then the 1.7.1 ethernet driver drops
into "sink" mode.  This means that network programs will be able to talk
to each other within the same machine.

It would have been nice to know the "error about /dev/ip file".  My
guess is that it is "Permission denied", because access to /dev/ip is
limited to root.
