Yes and no. The driver does what the EEPROM tells it to. The windows-driver ignores the EEPROM-config, and forces his own preferences. Which makes the EEPROM a worthless feature. The driver you're using looks in the EEPROM for it's config. Using mii-tool doesn't change the config of the card. It modifies what the hardware advertises to it's link-partner. do a rmmod 3c59x ; modprobe 3c59x options=[x] to force a preference. http://www.scyld.com/network/vortex.html tells you about the options available. > I experience many problems with cards not in autonegotiate > (driver say no cable or other, it work ramdomly). The same card with eeprom > setted correctly work perfectly under windows. I used to have some 200+ machines with various 3c905*-cards and Cisco catalyst switches. Lot's of trouble, until we removed all forced connections, replaced the 'bad' cables and let auto-negotiation do it's job. If a correctly configured link doesn't choose to use 100Mbit, most of the times the cable is miswired. Many cables have their pairs laid out as 1&2, 3&4, 5&6, and 7&8. That's not right. It should be 1&2, 3&6, 4&5, 7&8. EIA 568B is the right mapping, and http://www.ge.infn.it/calcolo/faq/rete/cat5cable.htm gives you the right mapping.
