I have a 486 with 2 Netgear EA211 cards in it.  They're also an 'ne'
clone.  I have the following in /etc/modutils/local.conf

    alias eth0 ne
    alias eth1 ne
    options ne io=0x300,0x320

(after editing a file in /etc/modutils run 'update-modules')
This is all that I need.

You need to find this out.  ISA isn't so friendly when it comes to
auto-probing.

That would probably work, if the addresses are correct, because that's
the same syntax I have in my config file.

I think there are some, but I don't have any familiarity with them.
The main issue with such tools is that probing certain ISA devices
will cause the system to lock up.  That's just the way ISA works.
(and one good reason for PCI to have superseded it)
