        Check to make sure the 'clones' are supported by the ne.c driver,
        and if they are, make sure any appropriate #ifdef's are enabled
        when the driver is compiled.

        For instance:

                /usr/src/linux/drivers/net/ne.c

        ..I notice some comments about only supporting *certain* clones,
        and in my ne.c those appear to be #ifdef'ed out:

----
#ifdef SUPPORT_NE_BAD_CLONES
/* A list of bad clones that we none-the-less recognize. */
static struct { const char *name8, *name16; unsigned char SAprefix[4];}
bad_clone_list[] __initdata = {
    {"DE100", "DE200", {0x00, 0xDE, 0x01,}},
    {"DE120", "DE220", {0x00, 0x80, 0xc8,}},
    etc....
----

        So verify your module was compiled with that flag enabled.

        Hmm, if one works, seems odd the other doesn't.
        But it might be related to the above.

        Maybe try bringing the devices up individually (instead of with modules.conf)
        using:

                insmod ne
                ifconfig eth0 up
                ifconfig eth1 up
                ..

        Other commands/arguments might be necessary.

        But do check to make sure your clones are supported by the driver, though.

1. Dual nics problem

We have to configure a server with two nics (both d-link). Both nics
are well configured, ifconfig shows correct ip's. Our problem is, that
we can ping to eth0 (192.168.64.19), but don't eth1 (192.168.65.19).
System is SUSE 6.1 with kernel 2.2.
Can anybody help ?
