Here is what I want to do:

I want to boot off of a CD ROM into a ramdisk.
I then want to nfs mount another drive with various software which I
may either want to run from there, or copy down to the ramdisk.

I have found a little info at
http://www.netbsd.org/Documentation/bootcd.html
and
http://www.mclink.it/personal/MG2508/nbsdeng/chap-misc.html

But I haven't found any good documentation on setting up and using a
ramdrive. Can anyone point me to some good clues?

Thanks a bunch,

   larry
