Can you expand on > it? Ooops, i didn't notice this also went out to the list. (For some reason, Mutt doesn't notice the list address on Bruce's mails, and marks them private.) I've already mailed this to Bruce privately, the ep driver always reads the ``identification port'' (3Com's private PnP solution, i believe) on address 0x100, and figures which 3C5x9 cards are installed on what address and IRQ. May this be invasive or not -- it's done anyway, so simply _using_ these data later doesn't make things worse, but would allow for using the first found 3C5x9 card with their native data, as opposed to hard-coded kernel ideas. -- 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. ;-)
