What are these .smi.bin files I keep seeing.  For instance, one is 
System_7.0.1.smi.bin.  The directories don't have text files explaining 
what I do with these files.  The files usually are too large to dd off to
a floppy, but they aren't ISOs either (unless they are ISOs by another name),
so I can't make boot CDs. 

I think the CD-ROM I have in my 840av is bad because I tried setting it to
what I believe is SCSI ID 6, and still it isn't working (the scsi ID pins
are labeled 0, 1, and 2.  I have pin 0 off, and pins 1 and 2 on).  I don't
currently have any other CD-Roms to try with it... Wait, I just realized
that the 7100 has a CD-Rom in it.  Maybe it will work...

I haven't been able to find this matrix.  Mind pointing me to it?

Yes.

Ack.  I have no idea what this means.  I reset the switch and NFS, SMB, SSH,
telnet, httpd, IPX, etc work fine on it between assorted suns, linux machines,
and windows machines.  I'm not much of a networking guru.  If I move the Mac
to a hub attached to the switch (the Hub having a pair of linux machines on
it, but not the DHCP server), would this prevent the port blocking thing
you describe?  I'll try it just in case...  Nope didn't work.  Now trying
moving the DHCP server to the hub also...  Nope, didn't convince the Mac
to pick up DHCP either.

Yes, the switch port is just fine.  I just double checked it.
