I have an IBM PC RT running AIX 2.2.1 that I would like to connect to our Ethernet network. I've run an Ethernet transceiver drop cable (2 10 meter sections) to a port on a DELNI, and the RT TCP/IP configuration files have been properly set up (as far as I can tell). There are VAXen on the Ethernet that run SRI Multinet (TCP/IP), and one of them is set up as my domain name server. When the RT is started, it tries to configure the ethernet device (net0). After a period of time, I get a console message saying that net0 has timed out, and that the device has been removed from the configuration. Has anyone done what I'm attempting? Any information would be greatly appreciated. Thanks in advance. -- Don Rainwater, University of Cincinnati Computer Center rainwatr@ucbeh.san.uc.edu rainwatr@ucbeh.bitnet rainwatr@ucqais.uc.edu

Could it be that the jumper settings on your Baseband adapter don't match the values given to `devices'? For some reason, the memory address and interrupt level jumper settings on the adapter as shipped by IBM don't match the default values used by `devices'. Being a software type, I changed the `devices' values: rsa from 80000 to 98000 rea from 81fff to 99fff brsa from 82000 to 9a000 brea from 87fff to 9ffff il1 from 9 to 3 Hope this solves your problem.

Running diagnostics and looking at your system configuration will tell you what interrupt level and memory addresses your ethernet card is set to. Then you can match that in devices. So you don't have to take the box apart and pull the card. It will also tell you if you have any other adapters which have overlaps or conflicts in terms of interrupt levels, and I/O space or AT bus memory overlaps, at least for your IBM supplied adapters. Diagnostics will also (look under communications utilities) bounce a message off of the ethernet, so that you can verify the connections you have back to the DELNI. Yes, I know that if diagnostics can do it, devices should..... :-) -- Nick Simicich --- uunet!bywater!scifi!njs --- njs@ibm.com (Internet)

Offhand, it sounds as if the plugging on the Ethernet adapter is set differently from the specification in the devices command. Check out the values set by devices by issuing: showdev adapt net0 from within devices and printing the results. Compare the rsa and il1 fields to the interrupt level and starting address on the card. Note that rea, brsa, and brea must be consecutive to rsa. Hope this helps.
