On my machine-

device ed0 at isa? port 0x340 net irq 10 iomem 0xd8000 vector edintr
device ed1 at isa? port 0x300 net irq  5 iomem 0xd8000 vector edintr

This is in a 486 66dx2 box.  I don't think that the 'iomem ...' means
anything because these cards (SVEC NE2000 "clones") don't have any boot
ROM.  I may be mistaken here because if you try to push a lot od data
through the box then sometimes the throughput is totally lousy and it
appears that the cards are dropping packets.  By themselves each card
appears to be able to do up to 600-700 Kb/s but sometime using ftp I
only get 7-10 Kb/s, and then other times it's in the 200+ range!

I've been meaning to replace these cards with some 3COM stuff to see if
it works any better...
