| The HOWTOs I found all assumed you had old cards with fixed addresses. 
| These could be specified as options in modules.conf. From the Net-HOWTO:
|          alias eth0 ne
|          alias eth1 ne
|          alias eth2 ne
|          options ne io=0x220,0x240,0x300
| But this does not seem to apply to the 3c59x driver. modinfo doesn't 
| even list "io" as a valid option.
| 
| I did find:
|   1) in /proc/ioports, one of the devices is listed with "(#2)" after it.
|   2) in /etc/sysconfig/hwconf, one of the devices has
| subDeviceId = 00d4, the other 00de.
| 
| I have tried changing the order of loading modules, along with a few 
| vain attempts in modules.conf. For info, this is a Redhat system. 
| Where is the definition as to which device will be associated with 
| eth0 made?
| 
| Any assistance would be appreciated. I did try to RTFM, I just can't 
| find the correct "fine manual";-)

I did a mini-howto for 'nameif'.  URL is below.  Maybe it can
help you.
