What does eth0 warning 'no MII transceiver' mean?

Post by Hartgeor » Mon, 10 Jan 2000 04:00:00



Hi,

Fairly new to linux and I am having trouble setting up a network via ethernet.
I suspect it is due to a eth0 warning I recieve when I boot up    When the
kernel boots up I get the following:

        epic100.c:v1.04 8/23/9* Donald Becker
        eth0: SMC EPIC/100 at 0xda00, IRQ 12, ff:ff:ff:ff:ff:ff
        eth0: ***WARNING*** No MII transceiver found!

        I was hoping someone could explain to me what this warning means so I can
determine if it is the cause of my networking problems.

(I have a  EtherPower II SMC9432TX Ethernet card.)

Thank you,

George Hart
San Diego

Seems the driver does have a serious problem with detecting the card.
Even the ehternet address does not look very nice. The driver however
should be intended for this card. Maybe you find some information about
the problem (or a later version of the driver) on
http://cesdis.gsfc.nasa.gov/linux/drivers/epic100.html

Is your NIC a 10 Mbps one? Some time ago i received this reply by Donald
Becker:

-------

This is normal with a 10mbps-only board -- the MII transceiver only
exists on the 100mbps 3c905 board.

1. What does eth0 warning no MII transceiver mean?

It sounds like you may have a card with attachments for both
Rj-45 and AUI. You may need to obtain a diagnostic disk to
switch from AUI to RJ-45. Most modern cards have autodetection
routines to detect link state. Since you are using a driver
which shows 100-m capabilities, I would expect it to be auto-
detecting, but I have no real experience with SMC network
cards.
