writing EEPROM with tulip-diag

[B Mohrgan Pratten]

After now reading the web page "http://www.scyld.com/diag/index.html"
describing the tulip-diag program I have a question.

I have a Macronix 98715 PMAC card that works, but insists on
full-duplex.  Running tulip-diag -ee seems to indicate that the eeprom
has no transceiver information.  Can I use tulip-diag -E to have the
eeprom written with relevant data?

tulip-diag -ee /*gives*/
tulip-diag.c:v1.19 10/2/99 Donald Becker (becker@cesdis.gsfc.nasa.gov)
Index #1: Found a Macronix 98715 PMAC adapter at 0xe400.
 Port selection is 10mpbs-serial 100baseTx scrambler, full-duplex.
 Transmit started, Receive started, full-duplex.
  The Rx process state is 'Waiting for packets'.
  The Tx process state is 'Idle'.
  The transmit threshold is 72.
EEPROM size is 6.
 A simplifed EEPROM data table was found.
 The EEPROM does not contain transceiver control information.

Using the default interface 'eth0'.
SIOCGMIIPHY on eth0 failed: No such device

Dose this mean that the card can not do auto negotiation?  In reading
other post to the list, I have got a different impression.

Will rewriting the eeprom be at all useful | helpful?

By the way dmesg reports that:
Linux version 2.2.12-20 (root@orca) (gcc version egcs-2.91.66
19990314/Linux (egcs-1.1.2 release)) #11 Thu Nov 18 15:01:24 EST 1999
tulip.c:v0.91g 7/16/99 becker@cesdis.gsfc.nasa.gov

A bit confused
Mohrgan.
