installing FreeBSD 4.5 on a MS-6378 main board

I wasted over an hour trying to install FreeBSD 4.5 on a new einux 1-u server. The main board is a MS-6378 board with a ADMtek AN983B on board nic card.

The "nic" is found during the install

dc0:  <ADMtek AN985 10/100BaseTX>  port 0xe800-0xe8ff mem 0xd8000000-0xd80003ff irq 11 at device 15.0 on pci0


 and I'm able to configure the  "dc0"  DEC/Intell 241143 (and clone)

I can ping the ip address of the card but can't ping the gateway. I checked my subnet and gateway and cable they are all correct. I get a link light on the hub.

I wonder if the problem is the ADM PXE bootROM. I tried a couple of settings.

The box takes forever to load and hangs on "sendmail" for about 3 minutes before booting to a root prompt.

But still no joy.

HELP !!!

Andrew

Hmm, there could be a number of reasons that networking isn't functioning.

There could have a link speed/mode mismatch between the NIC and whatever it connects to. 'ifconfig dc0' will tell you what speed and mode the NIC is using. That has to match what the other end is using, like 10HDX or 100HDX for 10Mbps or 100Mbps hub, respectively. If the other end is a switch the link could operate in any mode, but 100FDX would be the most likely. in the case of managed switched you could ask the switch what mode that port is in.

There could be an interrupt conflict, where two devices are both attempting to use IRQ 11, which can allow transmitted ping packets out, but fail to see the return packet. One symptom of this is a positive Opkts count in the output of 'netstat -i dc0' but a zero value for Ipkts. You can also see that happening by running a sniffer on another machine in the same collision domain. If the sniffer sees the outgoing packet and the return you know that the problem is isolated to the NIC/driver on the FreeBSD box.

It's always a good idea to be sure that the cable and port are good. Simply having a link light doesn't indicate that there's a usable link.

And then there's the possibility that the driver simply isn't compatible with that card.

The speed matched, sniffer showed nothing. I spoke to einux.com the guys that sold me the computer. They say they problem is with the NIC and FreeBSD. I will buy another mainboard.

Thanks ,

My mistake has been assuming they know nothing. The guys at einux were pretty knowledgeable.

Right, some are and some aren't. I learned quite a while back that it was more efficient to not spend too much time fiddling with a problem like this before calling the vendor. Sometimes they don't have a clue, but often they do or can point you to someone/someplace that does.

This i a problem with this Adapter having the wrong ID on board.  The ID is 0x9511 it should be 0x1983.
ADMtek even has a utility to change the id.  I have the same board, and have been looking into issues for it.  I'd give that a werl and see what happeneds.

Thanks for the info. I sent the box back. But it sounds like your solution would have worked.
