Oh well.  I guess I was figuring it was like the hp300 bootloader which 
can do that.

Ah, that only works once I have my system running NetBSD.  Too bad 
installboot doesn't work, since that can be run from another NetBSD 
platform.

OK, so what you're saying is that even if I got NetBSD onto a had 
drive, it wouldn't run from it, so I'd need to use an nfs root 
filesystem.  And since when I netboot a kernel it doesn't find the nfs 
root, I'd need to have a root filesystem on disk, which doesn't work.

That kinda makes it difficult for me to try playing with this platform 
:(

So, how exactly do you have your setup running?  Or is it simply an 
ethernet issue with iee?

OK, like I said, I thought it was like the hp300 bootloader.  
Nevertheless, build.sh release ought to bundle up the GENERIC kernel 
into a netbootable format, so first-time users don't need to install 
all the source code and cross-compile a toolchain just to get 
nbhp700-mkboot.
