Hello,
I'm having some difficulties getting the Ethernet interface to work on a Compaq
Deskpro XL 590. Currently ifconfig on this machine results in a syslog message
reporting 'lnc0: Initialisation failed' (which perhaps means that the
initialization failed).
I am using 2.2.2-RELEASE. My procedure is as follows:
1. boot from custom boot floppy that does not go into /stand/sysinstall but
instead starts /etc/rc script containing just /stand/sh. it also has ifconfig,
mount, ping, route, and dmesg (crunched dmesg isn't working thus no verbose
boot info in this note. i could use some help here too maybe. separate issue).
2. boot -c. set port for lnc0 to 0x7000 and continue boot. the
hardware is probed. i see the following:
a. pci0:0 is probed but no driver is assigned. (bad sign or not?)
b. lnc1 shown to be detected even though there is only one interface. this
is immediately after pci0:0 is probed. (hmmm)
c. lnc0 is shown to be detected later on when the rest of the Ethernet
interfaces are looked for.
3. /stand/sh is invoked. from command line issue:
# ifconfig lnc0 161.76.4.7
lnc0: Initialisation failed
^ ^ ^
(note case and spelling.)
4. pinging 161.76.4.7 works but pinging another address that should go out
the interface reports that 'network is down'. play with routing for a little
bit to see if everything is ok there. same results. ifconfig -a reports
that the interface is up. the interface is plugged into a hub.
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.
2. the hardware is as follows:
Compaq XL 590
Pentium 100
32 MB RAM
512 MB SCSI IBM HD
on board PCNet Ethernet/SCSI Host Adapter (see below)
Chip Data:
the chip labeling for the Ethernet adapter is as follows:
PCNet (tm) - SCSI
AM79C974KC
9434CP8 A4
1993 AMD
here is what Compaq has to say about the PCNet-SCSI chip:
Pcnet-scsi Chip
The Compaq Deskpro XL series packs new levels of power through the
PCneto-SCSI chip. Jointly developed by Compaq and Advanced Micro Devices
(AMD), PCnet-SCSI is the first chip to fully integrate both the 32-bit
Fast SCSI-2 controller and 32-bit Ethernet NIC on the PCI local bus on the
system board, saving not only the expansion slots that would otherwise be
needed for SCSI and Ethernet add-on boards, but also the cost of the
controllers themselves which typically cost several hundred dollars each.
PCnet-SCSI provides customers with a higher-performance network-ready
solution that is compatible with all major operating systems.
3. in looking through the mailing list archive it appears that this has
been a problem in the past for some Compaq platforms. in some cases resolution
may have been obtained by setting the port for lnc0 to 0x7000. other
cases appear to be unresolved faulting Compaq's PCI bus which may not
conform to accepted standards on some models.
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.
any help would be appreciated.
best regards,
William
