I'm trying to re-install NetBSD on a PC, actually several machines 
with similar configurations.  I'm not a wizard, but I've done this 
several times on these machines so I wasn't expecting any troubles. 

I can't get through the network setup stage.  The pings don't work.

I think the problem is that I (now) have too many network interfaces 
on these boxes.  I see an occasional message telling me to make NMBCLUSTERS 
bigger.  These machines have 4 Intel 82558 Ethernet chips.  When 
I did the network install successfully they only had 2. 

I expect it will work if I yank that card.  (The machines also have 
a Tulip I can use.)  But that's a pain.  Is there any obvious workaround? 

Is there a simple recpie to make a boot floppy from an existing kernel?  
I took a quick look in src/distrib/i386/floppies, but I'm in over 
my head.
