Installing a NIC Card in SCO Openserver 5.0.4 2

[joemama613]

I have SCO Openserver 5.0.4 running on a PC, and I have installed a 3COM NIC card. I installed the 3COM drivers, and the card popped up in netconfig. I installed it along with TC/PIP.

It is connected to a Netgear Router running DHCP, where the addresses run 192.168.0.xxx.

How do I get this to work? What IP address do I assign in netconfig? What does the /etc/hosts file have to look like (I might have fooled with that a bit too much!).

Also, the card is using IRQ 12, and I see a message on bootup as follows: %e3G Unable To Add INTR Handler (12).

Can anyone help? I don't know why this has to be so difficult!!!!

Assign an IP that the router is NOT handing out via DHCP. If the router hands out 50 IP's starting at 192.168.0.100, give the SCO box 192.168.0.10 or something.

netconfig should edit /etc/hosts for you one you give the proper IP to it. Basically, you need entry for localhost and for your nic:

127.0.0.1    localhost
192.168.0.10 my.server.com

If the 'Unable To Add INTR Handler (12)' error doesn't go away, you will need to fix this as well. Some PS/2 mice use this IRQ and could be why the nic can't get it. run 'hwconfig -hc' to see if there are any existing conflicts.

HEMO, thanks for the initial reply. I have set the IP address to 192.168.0.100, as the router starts at 1, and will never get past 30.
My /etc/hosts file looks good as you've told me. The 'hwconfig -hc' command returned "No obvious conflicts in hardware settings" but still displayed the line "e3G Unable to add INTR handler (12). I am at another dead end. Can you help?

change the interupts available to pci devices in your bios setup. then pay attention to what intr the pc assigns your nic on bootup, you may need to reconfigure via netconfig.

note hwconfig shows you how you have things configured
hw will actually go out and probe the hardware.

Thanks for all the help.

Here is where I stand. I tried everything I knew how, and a few that I didn't, and with all the help could not get rid of the boot-up message "Unable to add INTR Hand....".

Finally, I switched PCI slots, and removed and reinstalled the card, and it was recognized upon boot up.

Now, the port on the router is lit, and I can ping the unix machine from others on the network, and I can ping others from the unix machine.

However, when I go into my router's set up, the IP address that I assigned to the SCO machine is NOT in the DHCP table.

Does anyone know why, and is it important that it be there?

Thanks

Joe

It's not there because the router didn't assign it.

Only the IP's assigned by the router will show up there automatically. Some routers (siemens is one) have an option for you to add static IP's to the routers table making it easier for you to assign services to those PC's. (select dest pc from list rather than typing in IP every time)

Thanks to all for your help. It is much appreciated.

I have a similar problem with installation of the network card (3C980C - TXM) on SCO OpenServer 5.0.4. When I add NIC into the system using NETCONFIG I see the message "Bad string", but it does not interrupt the installation and then I see the message "Installation completed successfully". Relinking of the kernel completed successfully too. But during system boot I see the message "3Com 3c90x/3c980, unit 0: Cannot read PCI configuration space(0).". As result, network card does not work. Can anybody explaine what`s wrong? Thanks an advance.

Alex73,

It has something to do with the fact that the BIOS is not seeing the NIC card at all. What I did is I found somewhere in the BIOS (each machine is different, of course) where it allowed me to release all the PCI card assignments and renew them. Once I did that, I had no problem. Hope this works for you.

joemama613?

Thank you very much for your response, but it`s not a solution of my problem. I have an utility software (for DOS) for my 3C980C NIC and I have tested my card using this software. All tests have completed succesfully. I`m sure something has happened with my SCO OpenServer 5.0.4, because there was installed 3C900B NIC into my system and everything was all right. Before replacement of the NIC I have removed 3C900B driver from the kernel and it`s software, then I installed new software for the 3C980B NIC and inserted new 3C980C card into my computer. What was after that - you already know.
