This was a workaround to get the ISA Lance probe/attach code to find the PCI Ethernet chip, and is necessary in FreeBSD-2.1.x. I added the code to attach PCI versions of the Lance late last year, and you should no longer use that workaround because it will make the attach fail! > a. pci0:0 is probed but no driver is assigned. (bad sign or not?) That's OK. It is part of the chip set, which has been configured by the BIOS and will be used (of course :) but in no way reconfigured later. > b. lnc1 shown to be detected even though there is only one > interface. this is immediately after pci0:0 is probed.

Well, and this is where it fails !!! You have attached the same device twice, and two drivers compete for it. > 3. /stand/sh is invoked. from command line issue: > > # ifconfig lnc0 161.76.4.7 > > lnc0: Initialisation failed > ^ ^ ^ > (note case and spelling.) Please do NOT configure lnc0 to probe port 0x7000. Use lnc1 as the name of the network interface. ISA devices are probed after PCI, and the PCI attach could not know whether or not the ISA attach might connect a real ISA Lance card as lnc0. I've prepared the PCI code to support "wired" devices, but since the code for the other bus types has to cooperate, I did not enable that feature, yet. > Other points: > > 1. another point that might be interesting (or not) is that ifconfig -a > reports that there are two lnc interfaces (lnc0 and lnc1) yet there is > only one adapter. configuring either interface yields the same result. Yes.

This was indeed the solution for 2.1.x (FreeBSD-stable as of one year ago). I can't prevent old articles from the mail-archive stating a no longer valid work-around :( > 4. floppies/boot.flp does not work on this system. it appears to hang > when sysinstall would normally display its UI. this is not a problem as > it is possible for me to load the machine manually once the network > interface is configured. it is only a problem in getting verbose boot > messages as the fixit floppy which probably has a working dmesg is not > accessible. Hmmm ? I don't understand what's wrong here. You should be able to complete the boot procedure, if you don't reconfigure lnc0 ... > ---original message ends--- > > Doug White (thanks, Doug) responded to my original post and pointed out > that I did not mentioned that I tried booting without making changes to > the port address. Well, what *exactly* happens if you just boot with "-v" ? Regards, STefan
