Turns out that there may be system board BIOS interface problems with
the DEC chip drivers -- or at least for the SMC 8432...see below.

I tried approaching the problem from the other direction: the card was
working fine from WIN95 but not from Linux, so I downloaded the latest
kit from the SMC web site and as an experiment tried to load the
plain DOS ODI drivers from DOS -- and they failed with an utterly
meaningless error message.  Playing with the system I found that the
only way to make the DOS drivers load was to turn off the Plug-and-Pray
feature from the CMOS configuration screen; with it off I booted back
to Linux -- AND THE CARD NOW WORKS.  The interface will run or fail
depending on the setting of the PnP option in CMOS.

Obviously (I hope) there could be many reasons why the card might not
work in a particular environment, but if you've got a nonworking
net card using the DEC chip, try turning off the PnP option in the
CMOS setup and see if that makes it work.

In my environment the system board is a Micronics M55Hi with Phoenix
BIOS; this may be related to the problem since some hardware vendors
have described the Phoenix BIOS as the cause for many of the problems
that their customers have with PnP devices.

1. SMC Etherpower w/ DEC 21041

I've just got a SMC Etherpower which I've been trying to install
without a great deal of luck.  Unfortunately the card has a DEC 21041
at its heart which I've heard from a few people is not as stable as
the DEC 21040.  

I have tried both the tulip.c and de4x5.c drivers.  In both cases I
get the following messages:

firstly during the PCI probe:

        Unknown PCI device.  PCI Vendor id=6.  PCI Device id=14.

and then later during driver initialization:

        SIOCSIFADDR: No such device
        SIOCSIFBRADDR: No such device
        SIOCSIFNETMASK: No such device

The card when probed under DOS gives the following details:
        type: 8342BT
        slot: 16
        IRQ: 10
        I/O Base: F880

My system is a Dell P133c giving with the following PCI devices:
        PCI devices found :
        Bus  0 Device   0 Function  0.
            Host bridge : Intel 82437FX Triton (rev 2).
        Bus  0 Device   7 Function  0.
            ISA bridge : Intel 82371FB (rev 2).
        Bus  0 Device  14 Function  0.
            VGA display controller : Number Nine Imagine 128 (rev 0). 8259's
        interrupt 11.

If anyone has any clues then I'd be extremely grateful.  If not, I can
always return the card and get a 3c590.
