Installing ethernet device under LynxOS

Question

I changed my hard drive which was running LynxOS to another computer with diferent processor/mother board but same periphericals configuration. Everything is working except the network ethernet card. Leds are blinking properly and I reinstalled the drivers and build the kernel but it doesnt create the device when rebooting.

The only network devices I can see with the comand netstat -i are sl0 - 7 and lo0.

The network card is a PMC661J and the device should be rmx0.

Is there anyway I can see if the card is recognized by the system and why is not being related with the driver?

The LynxOS version is 3.0.0, but if you know how to do it in other Unix Systems please tell me and I will try it.

Thanks, Zits

Answer 1

Either you did not included the correct netwook driver in kernel
see (CONFIG.TBL)
either the device instalation did not detected your PMC PCI chipset

the interface will be crreated only by the device driver once device installation succeed

look at the devices command output it will tell you which devices have been configured in kernel and tell you the one that failed to be initialised.

I do not remember which chipset was in the Ramix PMC661J
the rmx0 interface name leads me to think the driver fort this PMC was provided by ramix (now GEfanuc)

Thanxs for answering Stef.

As far as the line I:pmc66x.cfg is included on file CONFIG.TBL and not commented and that the file pmc66x.cfg is under directory /sys/cfg I would say it is not problem of the driver but of the PMC PCI chipset.

The output of the device command are the following lines

 8  block 24         0         (no dev) 0     HDS 2-3

In another machine where I have the ethernet card working is that the rmx line is the following:

 27 char  28         0         (no dev) 0     rmx

Well, and different addresses in other devices, but I think that is normal.

So, looks like device installation didn't detected my card, what can I do?

Hardware has been tested and it is working with another microsoft OS.

Cheers

Answer 3

Solved, I had to configure on BIOS an IRQ for the PCI port in which the card was inserted. Thanks for your guidance Stef
