Since the EISA device will also respond on the ISA addresses, the driver gets confused otherwise. > This problem DIDN'T occur with FreeBSD version 1.1.5.1 on this machine! Because it didn't have EISA controller code, so the card has been handled as some sort of an ``extended ISA'' device. There was definately no EISA autoprobing in FreeBSD <= 2.1R, but it is there now. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
