3Com 3c515 Fast Ethernet card.

[Adam Rogoyski]

Booting the floppy25.fs image on a cyrix 5x86 vesa local bus machine,
it detected my ISA 3Com 3c515 100mb Fast Ethernet card, but said not
configured. I didn't see this card under supported or unsupported on the
i386 web page. Is it possible to get this card to work? I believe it's
an ISAPnP card. Below is the dmesg output from the floppy25.fs boot.
On an additional minor note, it called cpu0 a 6x86 when it's really a
5x86.

I believe the only unix-like OS supporting the 3c515 is linux. Donald
Becker did some driver work for it and a few other 3com cards. It is now
integrated into the linux kernel. Some source of his "Corkscrew" ethernet
driver is avail @ http://cesdis.gsfc.nasa.gov/linux/drivers/3c515.c

BTW- thses cards are a real bitch. I have one kicking around if someone
wants to work on a driver.

If you'd give a developer the card, I'd donate $100 US or so to the
developer or project as incentive to write the driver. I'd throw in a few
pizza's on me as well. I am unaware of any other 100mb isa card, and even
though the performance is terrible, I'd like to use this card anyways.

Intel makes 100BT isa, which works quite well.
