I need some information about the innards of a few 3Com Ethernet cards, specifically the EtherLink II (3C503 - IBM PC Bus), EtherLink Plus (3C505 - IBM PC Bus), EtherLink/MC (3C523 - IBM MicroChannel Bus), and the EtherLink/NB (3C543 - Apple Macintosh Bus). What I need to do is create a (hopefully) simple program that, when run on the PC in which the card resides, will return the card's type and Ethernet address, either to stdout or, optionally, append it to a file. I need to know (I think), which port on the card (e.g., base port + 3) to send what command(s) (e.g., 0x8c), so the card will return its type and six-byte Ethernet address from (possibly) a port (e.g., base port + 2). Can anyone help? Even if you know the answer for only one of the cards, please either post or email. If there's enough interest, I will summarize. Please note: I have directed Followup-To: comp.dcom.lans. -- +------------------+-----------------------------------------------------------+ | Peter Franks | pete@naitc.naitc.com | | NI9D | "I speak for myself, not A.C.
