Here's the patches to be applied to the files in /usr/src/sys/i386/isa.
The easiest way to apply them is to cd there and then feed each one to
patch (patch -p <this mail message). Once the patches are applied you'll
need to rebuild a kernel and install it before the driver will work.
If you haven't done this before just cd /usr/src/sys/i386/conf.
type config GENERIC or whatever kernel your running.
(you can find this out from the command uname -v)
then cd to /usr/src/sys/compile/GENERIC (use the same name as above)
make
and then make install
once it's finished you can reboot.
Make sure that you have configured the SMC 8416 card under DOS to
io address 0x280, the interrupt to 5, io mem address to 0xd8000, set the
network interface to what your using or auto select, and disable Plug and Play.
I hope this helps, here's the differences from the 2.0R source base.
