The SMC boards consistently work for us. The Linksys >10Mb/s only (RJ45, 10Base2 or AUI) boards consistently work for us. Unfortunately, that isn't true for the 21140 (or later) chips. Which is why I'm rewriting the de driver. The information to run the cards is in a serial EEPROM and my rewrite involves decoding that ROM and using the information to configure the card. However, it doesn't quite work right yet. Right now I only have limited number of cards that the support the SROM information and that makes testing problematical.
