You're welcome.  Here's a few more notes -- last night I moved that
EA-201 into my soon-to-be-router box.  To make the DOS system, fire up
windows or dos and
    format /s a:
now reboot with the floppy in the drive and you'll have DOS.  Not
much, but enough to put the setup floppy in and modify the EEPROM.

Most of my difficulty came from software that is "too smart" -- it
wouldn't let me set the IO and IRQ I wanted on one of the NICs because
"it conflicts".  Never mind that the only reason the NIC was in that
box was because my router box has no floppy drive!  I also found that
the NICs had half-duplex set by default.  (why it doesn't
auto-configure, I don't know)  I changed that to full-duplex but my
switch still shows it as half-duplex.  Oh well.  (oh, yeah, and I ran
the util on each card separately, I'd kinda like to see what it would
do if both NICs were in the box at the same time, then send a rant to

After sticking the two NICs back into the router box, the kernel would
only find one of them.  I have the 'ne' driver built in to the kernel,
so mucking with modules.conf leads nowhere.  The trick, as google
showed in the Linux-Ethernet HOWTO, is to have 2 ether= arguments in
the command line.  For the config I gave the NICs, it looks like :
    ether=11,0x300,eth0 ether=15,0x320,eth1
Curiously enough, if I left the IRQ off of the second card, it came up
with 32 (not possible, I don't think) and would get watchdog timeouts
when trying to bring up the interface.  Now both cards are working

To summarize :
    1)  make a DOS system ("format /s a:")
    2)  boot it and run the DOS util to configure the NICs, be sure
        and use different IO for each and spare IRQs
    3)  put the proper 'ether=' args in your bootloader or specify the
        IO (and IRQ) parameters in modules.conf[1]


[1]  the Right Way is to make a file in /etc/modutils/ to store the
     config and run 'update-modules'
