I hate to bother everyone with this, but its driving me nuts.  I'm trying
to install netbsd on my sparcbook (I broke solaris about a week ago, and
don't have a version that will run on it, so its been doing nothing), and
I can't seem to get it to boot from cd.   "boot cdrom" gives the
following:
"bad magic number in disk label"  
"can't open disk label package"


"can't open boot device"

Do I need to pass any arguments to tell it where on the cd to boot from?
Or did I just download an ISO I can't boot from from?
Thanks,
Mike
