The following are diffs I needed to make to get a Znyx ZX342 10/100
board working under FreeBSD. The two orignal files /sys/pci/dc21040.h
and /sys/pci/if_de.c were taken from the 2.0.5 release. I hope
these or similar changes can be made to the driver as we would like
to be able to install FreeBSD with these cards. Which brings me to
one other question. How could I create a boot/installation floppy
(with for example with these driver changes) myself? Thanks.
