It's possible (hey, it's certain, I don't expect you to lie) that some cards behave like this, but it's quite surprising. Most 8390 clones load their MAC address from a serial EEPROM; many of the integrated PCCARD 8390's use the same EEPROM that the CIS comes in from. How many cards do you know of that exhibit this behaviour? -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\
