Transmitter stopped with 21143/QS6611 NIC on 10BaseT

Thu Oct 1 19:56:45 1998

I have a 21143 / QS6611 NIC. I am using Slackware 3.5 (2.0.34 kernel)
and v0.89h of tulip.c. I did tried 0.89k too. I have to get it works
with my existing 10BaseT network. This NIC is working fine under Win98.

I just can't get this NIC to operate in 10BaseT mode. Correct me is I am
wrong:
>From the spec of 21143 and QS6611, I understand that there are two ways
to switch between 10/100Mbps:
1. Use a relay to switch between 21143/10BaseT and QS6611/100Base output

2. All go through QS6611 and switch between 10/100 by controlling  TXSEL
(and optionally BTSEL and MM pins).

I have tried to modified the tulip.c and force the 21143 to use 10BaseT
only, but I failed. What do I miss? Are there any way that I can tell my
hardware configuration by the content of the EEPROM?

Below are some information for your reference:

When Linux boot up it shows:

1. If I do not specified the "options" or "options=0" of tulip.o in
/etc/rc.d/rc.module, it will always in the 100mbps mode and jam my
complete network.

2. If I try to force it to 10BaseT by specify option=12 in rc.module,
the output tulip-diag is as below:

 This interface is missing the EEPROM.
  This is likely the non-primary interface on a multiport board.

3. If I commented out the tulip in rc.module:

Thank you for anyone that can give me some hints.
