I took a quick look at 3COM's web site and I did not see a 3C309B listed. I'm assuming it is an old card... What I did with my machine is let FreeBSD's install floppies figure out the on-board Realtek ethernet interface (since I could not figure out how to get this information any other way!) I then ran the 3COM Etherdisk configuration utilities against the 3Com cards I was installing. I started with the 'automatic configuration' option to see what it would do. Then I went back at the card with manual configuration to select IRQ and memory segments that did not conflict with anything else. I then saved the configuration to the card and exited the Etherdisk utilities. (On an older prototype I had 3 3C509 cards which I had to install and configure one at a time.) Anyway, Once I got the hardware configured the way I wanted it, using DOS, the Etherdisk utilities and some other tools, I created a custom kernal plugging in each of the IRQ and memory segments. e.g.: (from the GENERIC kernal): device ep0 at isa? port 0x300 net irq 10 The 'trick' is, each ethernet adapter needs its own unique IRQ and unique memory segment. Once you set the IRQ and memory segment in the card, you have to build a custom kernal that agrees with the hardware. I hope this information is of some use to you. Cheers... "Do or do not.
