After installing NetBSD, I am trying to boot and configure it as instructed
in Matthew Theobald's guide. I am able to begin booting, but after the line
"root file system type: ffs" this appears:

panic: cnopen: cn_tab -> cn_def == NODEV

stopped in init at _cpu_Debugger+0x6: unlk a6

db>

I am using kernel 1.5 on a Quadra 700 with 20 MB RAM, and a 250 MB hard disk
partitioned thusly:

225 MB: Root+Usr
40 MB: Swap
Remainder: MacOS

I am using a Apple 12" Color Monitor (512x384), should the error be related
to video.
