After failing to boot NetBSD 1.5.1 on my 660AV, I found the post 
below describing my exact problem. Has anyone got a solution for 
this, or should I just try to find another UN*X to install on my Mac?

As Tom did, I used Installer 1.1h to install all binary sets from the 
official 1.5.1 release (not the X ones) and tried to boot with Booter 
1.11.3. The mini-shell in the Installer indicates that /sbin/init is 
where it should be.

Any ideas?
