Re: 3com NIC not working

["Bruce Daane" <bdaane cybcon com>]

I don't know if any of this will help you, I have real 3c509 cards they are
EhterLink III ISA and I think the 509's are all ISA cards (I could be wrong)
so you may be useing the wrong driver module for the PCI card. Looks like
the one you probably want to use is 3c59x.o

look here

How I got my 509's to work

I am using RH7 on 200mhz Dual Processor machine

I have 2 of them in this box, I did not build a special kernel but I might
 in the future. I could not get them to load with the other device modules
 or as a drop-in module from kernelcfg.

Here is what I did...

I added     append = "ether=0,0,eth1" to the top of  lilo.conf and ran lilo

Apparently this helps the kernel probe for a second nic. For 3rd and forth
nic etc adding ether=0,0,eth2 ether=0,0,eth3 to the append will purportedly
invoke more probing.

Downloaded the new driver source and compiled a new module from it.

ftp://ftp.scyld.com/pub/network/3c509.c

There is also some good information here but I did not find it all to be
useful.

(your existing driver module may work fine, I did this because I was hunting
 for solution.)

I renamed my old  3c509.o and put the new one in its place

      lib/modules/2.2.16-22smp/net/3c509.o

I downloaded the DOS utility from 3Com (3c5x9x.exe)
ftp://ftp.3com.com/pub/nic/3c5x9/
and took the cards out of plug and play mode and manually set the addresses
like this.

Card: 006097EEDF80       IRQ=5        I/O=210
Card: 00A028DBF1DA       IRQ=10       I/O=300

>From Xterm I ran   insmod lib/modules/2.2.16-22smp/net/3c509.o

And the module loaded nicely and as someone pointed out the lowest address
 card became eth0 witch in this case is 006097EEDF80

Then I open Network Configurator and activate eth0 and eth1 and I'm
 now surfing.. wazzuupp..!!

I had to fight with ipchains for a while but now the masquerade is working
well also.

I put insmod lib/modules/2.2.16-22smp/net/3c509.o in /etc/rc.d/rc.local and
 the module loads automatically but this loads the module too late for
 Network Configurator to activate them at boot time so I have to activate
them
 manually in Network Configurator but its working...

I tried "/etc/rc.d/init.d/network start" but this will only activate the
 lo interface, maybe someone can give me a pointer on how to use network
start
 properly to activate all my interfaces from rc.local .

Good Luck, hope this helps...
