i have a couple of clone-o boxes with intel chipsets. they're basically 
indentical cards, and they're isa, not eisa. BUT, the 3c509s i have work in 
some and not others. the symptom is that i can read the id information of 
the 509 just fine -- this is I/O address 0x100. I can read the enet 
hardware address and other info fine. What doesn't work is that 
the 509 never comes back after a reset has happened. The result is that 
the product id at 0x30a always reads back as 0xffff. I can swap 509s 
around and the problem stays with the box. 

is there a setup issue with the pciset (i'm still waiting on my docs) 
that could cause problems with the iob and other instructions?

any ideas welcome. This problem is observed with both netbsd and freebsd, 
although the if_ep drivers are quite different.
