Hi everyone,
I have tried to make 3COM Megahertz 10/100 LAN+56K Modem (3CCFEM556BI)
(LAN side) work with FreeBSD 3.2 with PAO3, and succeed in it. Here
I attach a patch for ep driver and an entry for /etc/pccard.conf. You
need to add an pccard.conf entry, apply this patch in /sys/i386/isa,
rebuild kernel and reboot the system. Of course, you need PAO3 system
prior to make this patch.
This patch just changes ep driver to support ONLY 3CCFEM556BI, and
as a result, other devices supported by original ep driver may not
work. (Is anyone inform me how to add new device driver?)
I got a lot of information of this card from Linux 3c574 driver. It
changes I/O port addresses and activate MII interface. I'm using
this driver on my ThinkPad 235 for several weeks and have no problem.
Please inform me your result if you try this patch.
