Well, the fix only went into the tree Tuesday, showed up in sup
wednesday, and then we'd left out a new register definition:(.  I dont
know when the next i386 snapshot will be cut, but it will be fixed
there.

The $64k question is, can you put bot the ne2000 and the ep0 device
into your machine, configure the ne2000 as the real interface, put a
net-10 address on the 3c509B, and do a tcpdump of the cable the ne2000
is connected to?


>My "solution" was to disable PNP on the card, and now it's working fine 
>(albeit as a 3c509 on ep0, instead of a 3c509b on ep1).


Sure, that works too, if you have a bootable DOS diskette and a copy
of the vendor utils.
