Hello. Thanks to Dave Huang on my last question - zapping the PRAM got me
past that part. Here is the message I am getting now:
---
"ARGH!! No boot device???? Only supports disk device for booting.
panic: cannot mount root.
Stopped at    _Debugger+0x6:   unlk a6"
---
I went back to the install utility to make sure /root was mounted from the
mini shell. However, when I issued the command "mount /dev/sd1a /root", I
got the response "/root: Device busy." I was able to mount /usr. I have
NetBSD installed on it's own drive (at SCSI id 2, which is the 2nd drive on
my chain). It is set up w/ 100MB for root, 100 MB for usr, and 40 MB for
swap. 

Any ideas? Thanks,

Nat Fellows
