Built-in DEC Tulip 10/100 card in DEC Personal Workstation 266i

[Kent Reuber]

I'm setting up Linux (RedHat 5.1) on a DEC Personal Workstation 266i, which
includes a 10/100 Ethernet daughter board attached to the motherboard. What
do I need to do to get Linux to recognize and utilize it?

I appreciate your help. I'm a newcomer to Linux on Intel; previously, I
been working with MkLinux on PowerPC.

Here's what I've done so far.

1) As a test, I installed Windows NT Workstation. It recognizes the card as
a "DEC PCI Fast Ethernet DECchip 21142". (Interesting, because it isn't a
PCI card. Fine. Microsoft has it's own way of seeing things :-)) Under NT,
I was able to use Internet Explorer, so the card, network cable and
connection definitely work.

2) Reformatted the disk. Installed RedHat Linux. In the setup process, I
tried to choose the option for DEC Fast Ethernet 21140, but the setup
program seemed to be unable to locate the card. The only choice that seemed
to work was the DEC 425,..., 500. Anyway, it seemed to like that choice,
and proceeded to let me configure the card.

3) On booting the system, I got the message:

eth0: media is unconnected, link down, or incompatible connection

4) After reading through some of the information on Donald Becker's Web
site, I downloaded (using another system) and compiled the "tulip-diag"
program. This gives me the following:
