3Com 900 ethernet card wont work

I just installed the latest RTP, and i am trying to get the network to work.
I am using a 3Com 900 - combo ethernet card. The windows partition got on
the network very easily, so i am sure the card etc are working.

The device shows up correctly on the list when i run “pci”. when i try to
ping it always says that “the host is down”.

I tried manually starting the io-net with all the options did vid etc
entered manuall as suggested earlier in this group.

Any help will be greatly appreciated.

Thanks

Hi Dennis,
I have two cards from that type on my QNXRTP ver.6.1.0 box and I managed to run
them. Here is how I did it:

  1. slay io-net
  2. io-net &
  3. mount -Tio-net “-opci=0x0” /lib/dll/devn-el900.so
  4. mount -Tio-net “-opci=0x1” /lib/dll/devn-el900.so
  5. mount -Tio-net /lib/dll/npm-tcpip.so
  6. now chek if there is /dev/socket
  7. on that point I started dhcp.client -i en1& as I am working " behind the
    walls "
    If this is not the case , then : ifconfig en0 netmask up

and be shure to setup the gateway : route add default up
Good luck !

Hi Dennis :
Try following:

  1. slay io-net
  2. io-net &
    at this point it should exist /dev/io-net
  3. mount -Tio-net /lib/dll/devn-el900.so
    at this point it should exist /dev/io-net/en0
  4. mount -Tio-net /lib/dll/npm-tcpip.so
    at this point check with "ifconfig en0 " → it will show you inet 0.0.0.0
    mask 0.0.0.0
  5. now make your configuration : ifconfig en0
    It must work !!!
    Regards !

I tried doing the exact same thing as suggested in reply to my previous post
(attachment). No errors are reported. but, the card never works. I checked
on the hub. The link and the activity leds dont come on. But i am sure it is
not a faulty connection because it works fine in the Windows partition.

There was a post in the new user newsgroup that there are some problems with
the 3Com 900-Combo card. Is there a fix for the driver ? The card i have
is a 3Com 900-Combo rev A, is the problem applicable to this rev?

Thanks,

Dennis…
