Hi:
I have my Solaris 10 x86 system up and running for more than a year using a 3COM 3C905CX-TX-M Network Interface Card.  However this NIC has failed and I replaced it with a 3C905-TX and I can't get the system running over the LAN again.

I'm looking for idiot-proof step-by-step assistance on getting my system running over Ethernet again.

Thanks

You have changed you NIC card, make sure your NIC card is on the Solaris 10 (Intel) hardware support list:

You need to reconfigure the kernal, have a look at the following page to learn more:

My NIC is on the HCL.

But a b -r doesn't make it work.

I know the NIC is working because when I configure the BIOS at boot time to boot from a MSoft XP hard drive - it works fine.

login as root, and type in "ifconfig -a" to see if the system can see your new NIC
or check the /var/adm/messages file for the new interface card name.

You need to create an /etc/hostname.interface  file (replace  interface with your new
interface card name)

eg:
you old NIC name is iprb0, the newone is iprb2 , you do
cp /etc/hostname.iprb0 /etc/hostname.iprb2

and then reboot the box, please repace iprbX with the real NIC name in your system.

If you have trouble to find out what the NIC interface name, you can try to run:
1) /usr/sbin/sys-unconfig
2)  reboot
3) boot the system and redefine your hostnam, networks by answering the boot questions.

Have a nice weekend!
